The Evolution of the Martial Arts Part II: Why Modern Martial Arts Exist

Why warrior arts, combat sports, self-defense, and military combatives evolved to solve different problems.

The Greek phalanx represents the defining purpose of the warrior arts: preparing individuals to fight effectively as members of a disciplined coalition. This article examines how that purpose shaped the evolution of the martial arts and continues to distinguish military combatives from other martial traditions.

Part II of a two-part series

The first article established the evolutionary framework underlying this paper, arguing that martial systems are best understood by the adaptive problems they evolved to solve rather than by their techniques or historical lineage.

This article applies that framework to develop a functional classification of the martial arts and explores its implications for military combatives and modern martial practice.

A Functional Classification of the Martial Arts

Draeger’s classification was fundamentally historical. It explained how the Japanese martial traditions evolved as the circumstances that had originally produced them gradually changed. That historical perspective remains extremely valuable because it reveals a process that occurred with unusual clarity in Japan. It does not, however, provide a complete framework for understanding the enormous diversity of martial systems that exist today. Modern martial arts no longer differ primarily because of their historical lineage. They differ because they have evolved to solve different problems (Draeger, 1973–1975; Friday, 1997; Bennett, 2015).

The evolutionary framework developed throughout Part I suggests that martial systems are most clearly understood by the adaptive problems they are intended to solve rather than by the historical traditions from which they descend. Techniques, equipment, and methods may often appear similar, yet the purpose for which they are practiced fundamentally shapes both the culture of the system and the criteria by which success is judged. A classification based upon function therefore provides a more useful framework for understanding modern martial practice than one based solely upon historical development.

Viewed in this way, contemporary martial systems naturally fall into three broad categories. The first consists of warrior arts, whose purpose is to prepare individuals to fight effectively as members of a coalition. The second consists of individual fighting arts, whose purpose is to prepare individuals to prevail in interpersonal violence, whether in genuine combat or in regulated competitive contests. The third consists of developmental arts, in which martial practice serves primarily as a means of physical development, character formation, recreation, cultural preservation, or personal identity.

These categories should not be understood as rigid or mutually exclusive. Most martial systems contain elements of more than one. A military combatives program inevitably develops individual fighting ability. A competitive fighting system may cultivate discipline and character. A developmental art often preserves techniques originally developed for warfare. The categories instead describe the principal adaptive problem around which the system is organized. That central purpose shapes its methods, instructional priorities, standards of excellence, and ultimately its culture.

The distinction is particularly important because techniques themselves frequently migrate from one category to another while their purpose changes completely. A grappling technique developed for the the battlefield may later become part of a civilian self-defense system, a competitive sport, or a vehicle for personal development. The technique remains recognizable, but the adaptive problem it is intended to solve has changed. Understanding that change requires looking beyond the technique itself to the function it serves.

The chapters that follow examine each of these functional categories in turn. Although they share a common ancestry in the warrior arts, they have diverged because they now solve different problems. Appreciating those differences is essential for understanding both the strengths and the limitations of each, and for understanding why Modern Army Combatives represents not simply another martial art, but an attempt to return martial training to its original coalitionary purpose.

Warrior Arts

The warrior arts are the original martial arts. They emerged to solve a specific problem: preparing individuals to fight effectively as members of a coalition engaged in violent conflict with another coalition. Every aspect of their instruction was judged according to that purpose. Techniques were retained because they contributed to success in war and discarded when they no longer did. The measure of excellence was never individual victory alone, but the effectiveness of the fighting group.

This distinction has profound implications for how warrior arts are organized. Individual fighting skill is necessary, but it is never sufficient. A warrior must be proficient with the weapons of his time, capable of moving and communicating with other members of the formation, physically prepared for the demands of campaign and battle, and psychologically capable of functioning under conditions of fear, exhaustion, and uncertainty. He must understand tactics, discipline, and leadership. He must also possess the personal qualities required by the warrior culture from which the art emerged. Technical skill therefore occupies only one part of a much larger system designed to produce effective warriors rather than merely effective fighters.

Throughout history, this pattern appears with remarkable consistency. The Greek hoplite did not simply learn to use spear and shield; he learned to fight as one part of a phalanx. Roman legionaries mastered engineering, marching, logistics, weapons, discipline, and coordinated maneuver because all were necessary to the effectiveness of the legion. Medieval knights trained not only with sword and lance but also in horsemanship, leadership, and the obligations of their social position. Steppe horsemen developed extraordinary riding and archery skills because those abilities formed the foundation of mounted warfare. Although the techniques differed enormously, the organizing principle remained the same. Every element of training ultimately served the effectiveness of the coalition (du Picq, 1880/1947; Keegan, 1976).

This explains why warrior arts are inherently broad. They cannot be reduced to hand-to-hand combat, swordsmanship, marksmanship, or any other individual skill. Those are components of the larger system, not the system itself. A soldier who is an exceptional marksman but cannot move with his unit, communicate effectively, or maintain discipline under fire is not fully prepared for war. Likewise, an outstanding grappler who possesses no understanding of weapons, tactics, or coordinated action has mastered only a fragment of the warrior art.

The distinction becomes particularly important in modern discussions of military combatives. Civilian martial arts often begin with an individual discipline and then build outward according to the interests of individual practitioners. Warrior arts proceed in the opposite direction. They begin with the mission of the coalition and determine what individual skills must be developed to accomplish it. The direction of development is therefore fundamentally different.

This broader perspective also explains why warrior arts inevitably include subjects that many modern practitioners would not recognize as martial at all. Land navigation, battlefield medicine, communications, engineering, logistics, physical conditioning, fieldcraft, and leadership all contribute directly to success in war. They belong within the warrior art for the same reason that weapons training belongs within it: each prepares the individual to function more effectively as a member of the fighting coalition. Hand-to-hand combat remains an important component of the warrior art, not merely because close combat sometimes occurs, but because realistic fighting develops the physical skills, confidence, and psychological resilience required of warriors long before those skills are ever tested on the battlefield (du Picq, 1880/1947; Keegan, 1976).

Understanding the warrior arts in this way also clarifies why they often appear less technically refined in particular skills than specialized civilian systems. A military organization cannot devote all of its training time to grappling, swordsmanship, or marksmanship because it must prepare soldiers for a much wider range of tasks. Breadth is not evidence of inferiority. It is a consequence of purpose. A warrior art sacrifices specialization in individual disciplines in order to develop competence across the many skills required by coalitionary warfare.

This distinction provides the foundation for understanding the divergence of the modern martial arts. Once martial training ceased to be organized primarily around the requirements of coalitionary warfare, individual components of the warrior art increasingly became independent disciplines. Grappling, striking, weapons, competition, physical development, and personal cultivation gradually separated from the larger system that had originally united them. Each retained elements of its common ancestry while adapting to solve a different adaptive problem.

Individual Fighting Arts

As civilization became increasingly specialized, many of the component skills that had once existed within the warrior arts gradually became independent disciplines. They retained much of their technical heritage while adopting a different organizing principle. Rather than preparing individuals to function as members of a fighting coalition, they increasingly focused upon preparing individuals to prevail in interpersonal violence. The adaptive problem had changed, and the arts changed with it.

The objectives of these systems vary considerably. Some prepare practitioners for criminal violence and personal self-defense. Others emphasize judicial duels, challenge matches, prize fighting, law enforcement, or modern combat sports. Despite these differences, they share a common characteristic. Success is measured primarily by the individual’s ability to defeat another individual rather than by his contribution to the effectiveness of a larger fighting organization.

This distinction profoundly influences both training and culture. Because the individual fighter is the central concern, instruction naturally becomes more specialized. Training time that would once have been devoted to weapons, tactics, logistics, leadership, or coordinated movement can instead be invested in refining particular aspects of individual combat. The result is often an extraordinarily high level of technical proficiency. The specialist frequently surpasses the warrior in the narrow domain to which his training is devoted, not because the warrior art is inferior, but because it is organized around a broader purpose.

Brazilian Jiu-Jitsu illustrates this specialization particularly well. The art has become one of the most technically sophisticated grappling systems ever developed, owing in large part to its emphasis on continuous live training and competition. Yet its organizing principle is not coalitionary warfare. Most training is directed toward defeating another individual under conditions intentionally designed to isolate grappling from the broader problems of actual combat. Weapons, multiple opponents, tactical movement, communication, and the responsibilities of functioning within a military unit are largely outside its principal concern. They may be addressed in separate self-defense curricula, but they do not constitute the central activity around which the art is organized.

The same observation applies, in different ways, to boxing, wrestling, judo, mixed martial arts, and many systems of civilian combatives. Each has evolved to solve a particular individual problem, and each has become exceptionally effective within the domain for which it is organized. The mistake lies not in the specialization itself, but in assuming that success within one adaptive problem automatically transfers to another. A world-class boxer is not thereby prepared for infantry combat. An outstanding grappler is not necessarily prepared for armed confrontation. Likewise, an accomplished soldier may not perform at the highest levels of competitive grappling because his training has been organized around an entirely different objective.

Competition occupies a particularly important place within this category because it provides an efficient means of developing individual fighting ability. Formal contests create clear standards of performance, encourage sustained practice, reward technical innovation, and establish credible measures of proficiency. Competition also accelerates technical evolution, because ineffective methods are repeatedly exposed and replaced through continual testing against resisting opponents. They also recruit one of humanity's oldest behavioral systems: ritualized competition for position within the social hierarchy. As discussed earlier, ritualized competition for position within the social hierarchy long predates humanity itself. Modern combat sports represent highly refined cultural expressions of that ancient pattern. The contest determines relative standing while dramatically reducing the costs associated with unrestricted violence (Tinbergen, 1963; Huber & Kravitz, 1995; Boehm, 1999).

It is important, however, not to confuse the value of competition with the purpose of the art. In the individual fighting arts, competition often becomes the central organizing principle. The championship, the ranking system, and the public demonstration of individual superiority provide both motivation and measures of success. There is nothing inherently improper about this. It reflects the adaptive problem the system has evolved to solve. The art exists to produce highly capable individual fighters, and competition is among the most effective methods ever devised for accomplishing that objective.

This perspective also explains why the culture of many modern martial arts differs so markedly from that of military organizations. Civilian academies naturally depend upon voluntary participation. Instruction is directed toward those individuals sufficiently motivated to pursue excellence. The academy therefore becomes a community of enthusiasts, each pursuing his own development. The military cannot operate on this model. Its responsibility is not to produce a handful of exceptional fighters, but to ensure that every member of the formation achieves a level of competence consistent with the requirements of the coalition.

The distinction is one of purpose rather than quality. Individual fighting arts represent some of the highest expressions of technical combat skill ever developed. Their methods have much to teach soldiers, police officers, and civilians alike. The error arises only when their organizing principle is mistaken for that of the warrior arts. They answer a different question. Rather than asking how an individual contributes to the effectiveness of a fighting coalition, they ask how an individual defeats another individual. Both questions are legitimate. They are simply not the same.

Developmental Arts

The final stage in the specialization of the martial arts occurs when fighting itself ceases to be the principal objective of training. Techniques originally developed for warfare or interpersonal combat are retained, but they now serve primarily as vehicles for achieving other ends. Physical fitness, character development, recreation, cultural preservation, spiritual discipline, education, or personal identity become the organizing principles around which the system is structured. Combat remains present, but it is no longer the reason for practice.

This transformation is neither unusual nor uniquely modern. Throughout history, cultural practices have often outlived the conditions that originally produced them. Hunting traditions become sports after agriculture reduces dependence upon wild game. Horsemanship survives as recreation long after horses cease to dominate transportation and warfare. The martial arts underwent a similar process of cultural specialization. As fewer societies required large numbers of professional warriors, martial practice increasingly became valuable for reasons other than preparation for war (Henrich, 2016).

Many of the disciplines commonly associated with the Japanese concept of dō illustrate this transition. Technical practice remains important, but the emphasis increasingly shifts toward the effect that disciplined practice has upon the individual. The repeated performance of demanding skills cultivates discipline, patience, perseverance, humility, self-control, and attention to detail. The practitioner continues to study martial technique, but the ultimate product is no longer simply a more capable fighter. It is a more disciplined person (Draeger, 1973–1975; Bennett, 2015).

Competition often remains valuable within these systems, but its purpose changes. As discussed earlier, competition is an ancient expression of the behavioral system governing social hierarchy. Properly structured, it provides immediate feedback, reveals weaknesses, and motivates sustained effort. In developmental arts, however, victory is not the final objective. Competition becomes a means of improving the practitioner rather than an end in itself. The opponent serves not merely as an adversary, but as an indispensable partner in the practitioner's development (Tinbergen, 1963; Boehm, 1999).

This distinction helps explain why many modern practitioners speak of martial arts as lifelong pursuits. The battlefield imposes a practical standard: effectiveness in war. Individual fighting arts impose another: victory over another individual. Developmental arts substitute a different standard altogether. Success is measured by continued growth. Technical skill remains important, but it is valued largely because of the qualities developed through its pursuit rather than the practical application of violence.

The emergence of developmental arts should not be understood as a corruption of the warrior traditions from which they descended. Rather, they represent an adaptation to changing social conditions. As civilization created an ever-expanding number of peaceful avenues through which individuals could attain position within the social hierarchy, fewer people required martial training for war or personal combat. Yet many of the educational and psychological benefits of disciplined martial practice remained valuable. The arts therefore evolved to meet those new needs while preserving important elements of their technical and cultural inheritance. In doing so, they continued the broader evolutionary process described throughout this paper: recruiting their technical advances while preserving the organizing purpose of the warrior art: preparing individuals to become effective members of a fighting coalition. (Henrich, 2016; Bennett, 2015).

Recognizing developmental arts as a distinct functional category also clarifies many otherwise confusing debates within the martial arts community. Questions concerning whether an art is “effective” often become contentious because participants are evaluating different adaptive problems without realizing it. A system designed primarily for character development should not be judged by the same criteria as one designed for military service or competitive fighting. Likewise, a military combatives program should not be evaluated according to standards appropriate for a developmental art. Each should be judged according to the problem it is intended to solve.

Taken together, the warrior arts, the individual fighting arts, and the developmental arts represent not competing philosophies but different branches of a common evolutionary tree. They preserve much of the same technical heritage while organizing themselves around different purposes. Appreciating those purposes allows each to be understood on its own terms while avoiding the confusion that results from judging one category according to the standards of another.

This distinction also prepares us to examine a recurring problem in modern military combatives. Because civilian martial arts now exist primarily within the individual fighting and developmental categories, they exert a powerful influence upon military instructors. The resulting tension between civilian martial culture and the requirements of a warrior art lies at the heart of many contemporary debates concerning the purpose of military combatives.

Modern Army Combatives: A Return to Purpose

Understanding the distinction between warrior arts, individual fighting arts, and developmental arts clarifies a recurring source of confusion within modern military combatives. The military frequently draws instructors from civilian martial arts, particularly Brazilian Jiu-Jitsu, wrestling, boxing, and mixed martial arts. These systems produce exceptionally capable individual fighters, and the Army has benefited enormously from the technical knowledge they provide. Difficulties arise not because these arts are ineffective, but because they are organized around a different adaptive problem than the one military organizations must solve.

The first purpose of a military combatives program is to develop generic fighting ability. Before soldiers specialize in the techniques, tactics, and procedures associated with their particular military specialty, they benefit from a common foundation of confidence in physical confrontation, controlled aggression, balance, composure under pressure, and the ability to continue functioning during intense interpersonal conflict. This foundation is not intended to replace mission-specific training. Rather, it prepares soldiers to benefit from it. Mission-specific training prepares soldiers for the particular circumstances they are most likely to encounter while accomplishing their unit's mission. Like all specialized skills, however, it must be built upon a more fundamental foundation. Just as a baseball player must first learn to throw and catch before mastering the double play, soldiers benefit from first developing generic fighting ability before specializing in the techniques, tactics, and procedures required to accomplish their unit's mission. That foundation develops the confidence, composure, and behavioral qualities upon which mission-specific skills can continue to be employed effectively, even when the battlefield departs from the conditions for which they were originally intended. An artilleryman must still master artillery, a tanker his tank, and a pilot his aircraft. At the same time, every soldier must be prepared for the possibility that the battlefield will collapse into close combat. Military history repeatedly demonstrates that soldiers of every specialty sometimes find themselves fighting in close quarters and hand-to-hand combat when plans fail, units become isolated, vehicles are disabled, ammunition is exhausted, or the enemy closes unexpectedly. The battlefield is inherently unpredictable. A military combatives program prepares soldiers for those possibilities while also developing the behavioral and psychological qualities common to warriors regardless of specialty.

The second purpose is psychological rather than technical. Close, physically demanding competition accustoms soldiers to many of the emotional and physiological realities of combat. Fear, uncertainty, fatigue, pain, frustration, physical exhaustion, and the necessity of continuing to function despite them are experienced repeatedly in training. Although no training environment can fully replicate the battlefield, repeated exposure to intense interpersonal conflict develops familiarity with many of the psychological demands common to both fighting and war. The objective is not to eliminate fear, but to ensure that soldiers discover through experience that they are capable of functioning effectively in its presence.

My own experience during the wars in Iraq and Afghanistan reinforced this conclusion. During the years of heaviest fighting, I routinely conducted post-action interviews with soldiers who had been involved in hand-to-hand combat. One observation appeared with surprising consistency. After describing the encounter, soldiers would often conclude with essentially the same statement: “It was like fighting a white belt.” The comparison was remarkably apt. Their opponents were typically aggressive, determined, and physically committed, but they possessed little understanding of how to fight against someone employing even basic grappling technique. They fought with tremendous determination, but without the technical understanding that comes through systematic training.

This observation illustrates an important principle. The purpose of military combatives is not to prepare soldiers to defeat world champions. It is to prepare ordinary soldiers to prevail in the kinds of close combat they are actually likely to encounter. The battlefield rarely presents carefully matched contests between equally trained martial artists. It more often presents chaotic encounters involving frightened, exhausted, and highly motivated individuals possessing widely differing levels of technical skill. Even a modest level of systematic training can therefore provide a decisive advantage when violence becomes immediate and personal.

The purpose of a military combatives program is not to produce a small number of outstanding fighters. It is to produce a unit in which every soldier possesses a functional level of fighting competence while reinforcing the behavioral qualities that make the unit itself more effective in combat. This distinction changes nearly every aspect of program design. The measure of success is not how many champions the program produces, but whether the average soldier becomes more capable, more confident, and more valuable to the coalition (Tinbergen, 1963; Boehm, 1999).

This difference in purpose naturally produces different cultures. Civilian academies generally depend upon voluntary participation. Individuals choose to attend because they enjoy training, seek competition, or wish to improve themselves. The instructor’s task is to develop those who have already chosen to be there. Military organizations cannot operate in this manner. Every soldier is part of the fighting formation, regardless of personal interest. A successful military program must therefore train the entire unit rather than merely attracting the most motivated individuals.

This distinction explains a common failure observed in military combatives programs. Instructors whose experience has been shaped primarily within the culture of Brazilian Jiu-Jitsu or mixed martial arts often build excellent clubs instead of effective unit programs. Participation gradually becomes concentrated among the small minority of soldiers who are intrinsically motivated to train. Technical standards within the club may become extremely high, while the overall fighting ability of the unit changes very little. The instructor has unintentionally solved a different adaptive problem. He has built an outstanding individual fighting program rather than a warrior art.

The difference is not simply organizational. It reflects the behavioral systems discussed earlier in this paper. Civilian academies rely primarily upon self-selection and personal ambition. Individuals train because they have already decided to compete within that particular hierarchy. Military organizations cannot rely upon self-selection because the coalition depends upon the competence of every member. The challenge is therefore to harness the ancient human drive for social hierarchy in a manner that motivates the entire formation rather than only its enthusiasts.

Competition remains one of the most powerful tools available for accomplishing this objective, but its purpose changes. In individual fighting arts, formal competition often becomes an end in itself. Championships, rankings, and public recognition encourage individuals to devote extraordinary effort toward technical mastery. These competitions are invaluable because they produce exceptionally skilled practitioners and drive the technical evolution of the art.

Within a warrior art, however, formal competition serves a different function. It identifies highly capable practitioners, develops instructors, and establishes demanding technical standards, but it cannot become the principal activity of the program because only a small percentage of soldiers will pursue it seriously. The broader objective remains the fighting effectiveness of the entire unit.

For that reason, informal competition assumes even greater importance. Every training session concludes with soldiers testing themselves against one another. These contests are not championships. They are part of the daily social life of the unit. Every soldier knows that his peers, leaders, and subordinates will observe his willingness to engage, his composure under pressure, his persistence, and his technical competence. No one is expected to become a champion. Everyone is expected to become a credible fighter.

This distinction reflects the evolutionary framework developed throughout this paper. Formal competition harnesses competition for social hierarchy among the small minority willing to pursue exceptional levels of performance. Informal competition harnesses the same behavioral system across the entire coalition. Because participation is universal, fighting competence becomes part of the unit’s social expectations rather than the hobby of a few enthusiasts. Competition remains the mechanism, but the adaptive problem has returned to its original purpose: strengthening the coalition.

Military combatives therefore measures success differently from civilian martial arts. Its purpose is not to maximize the technical ability of a few exceptional individuals. Its purpose is to develop the fighting capacity and warrior ethos of the entire formation.

When we began building the Army Combatives Program, I initially believed formal competition would be the primary engine driving improvement. Experience taught me otherwise. Formal tournaments are invaluable for developing exceptional fighters and instructors. If done well, in the overall context of soldiering, they also publicly identify and reward soldiers who exemplify the highest standards of the profession, providing visible examples of the qualities the Army wishes to cultivate. At the same time, the real transformation of the unit occurred in daily practice. When every physical training session, after the run or foot march, ended with soldiers testing themselves against one another, fighting ability became part of the social fabric of the unit. Every soldier knew that his peers and subordinates would witness not merely whether he won, but whether he continued to fight when tired, frustrated, or outmatched. It was this informal competition, repeated day after day, that changed the culture of the organization.

The principle is no different from the role of physical fitness in senior leadership. Few would argue that the primary value of a brigade commander lies in his ability to carry a heavy rucksack or run the fastest two-mile. His value lies in the knowledge, judgment, and experience accumulated over decades of service. History contains countless examples of commanders who directed campaigns while physically incapable of marching with their soldiers. Yet military organizations still expect senior leaders to maintain high standards of physical fitness. They do so not because physical performance is the principal contribution of a senior commander, but because leadership requires visible commitment to the standards expected of the force. Soldiers are more willing to accept hardship from leaders who willingly share it.

Combatives serves a similar function. The Army does not require every senior leader to become the finest fighter in the formation. It does require leaders to demonstrate, by personal example, that fighting competence matters. Participation communicates something far more important than technical proficiency. It demonstrates a willingness to enter the same demanding environment expected of the soldiers who will ultimately close with and destroy the enemy in close combat. That example reinforces the warrior ethos throughout the organization in a manner that no policy, speech, or written directive can achieve.

When senior leaders consistently participate in combatives training, they communicate that fighting remains central to the Army’s professional identity. When they consistently avoid it, soldiers notice that as well. The issue is not whether every commander can defeat every subordinate in a grappling match. Such an expectation would be both unrealistic and irrelevant. The issue is whether leaders visibly embrace the standards and culture they expect others to uphold. In a warrior profession, participation in demanding training is itself an act of leadership because it demonstrates commitment to the values upon which the fighting effectiveness of the coalition ultimately depends.

Modern Army Combatives should therefore be understood not as another civilian martial art, nor as a simplified version of Brazilian Jiu-Jitsu or mixed martial arts, but as a contemporary warrior art. It draws freely from the technical advances of the individual fighting arts because those arts have refined methods of developing individual combat skill to an extraordinary degree. Yet it organizes those methods according to a different principle. Individual skill serves the coalition, not the reverse.

In this sense, Modern Army Combatives represents less an innovation than a restoration. Civilization gradually separated the warrior arts into increasingly specialized disciplines as military service became only one of many avenues through which men sought position within the social hierarchy. Modern Army Combatives reunites those disciplines under their original organizing principle. It employs competition without allowing competition to become the purpose of training. It develops individual fighting ability without forgetting that the soldier’s ultimate task is not to win an individual contest, but to fight effectively as a trusted member of a coalition.

Confusing Purpose with Technique

One of the most persistent errors in discussions of the martial arts is the assumption that techniques determine the nature of a system. They do not. A technique has no purpose independent of the problem it is intended to solve. The same arm lock, takedown, sword cut, or marksmanship drill may appear in a warrior art, an individual fighting art, or a developmental art while serving entirely different functions. To classify martial systems by their techniques is therefore to mistake the means for the end. Purpose determines organization. Techniques are selected, modified, preserved, or discarded according to how well they contribute to that purpose.

This distinction explains why debates over “which martial art is best” rarely produce meaningful conclusions. Participants often assume they are discussing the same question when, in reality, they are evaluating different adaptive problems. A soldier preparing for combat, a police officer making arrests, a civilian concerned with personal protection, a mixed martial arts competitor, and an individual seeking physical discipline are not attempting to solve the same problem. It should therefore surprise no one that the optimal training methods differ.

The same confusion frequently appears within military organizations. A highly accomplished competitor is often assumed to possess the knowledge required to build an effective military combatives program. Competition certainly demonstrates exceptional individual fighting ability and frequently develops excellent instructors of individual combat. It does not, by itself, provide an understanding of how to train an entire military formation. Those are different educational problems and therefore require different organizational methods.

The reverse misunderstanding also occurs. Military combatives are sometimes criticized because they do not produce the same degree of technical specialization found among elite civilian competitors. Such criticism mistakes breadth for deficiency. A warrior art cannot devote all of its time to perfecting a single skill because it must prepare soldiers for the much broader demands of coalitionary warfare. Every hour devoted to one subject necessarily comes at the expense of another equally necessary military skill. The apparent compromise is not evidence of lower standards. It is evidence of a different purpose.

Recognizing the distinction between purpose and technique also changes how martial traditions should borrow from one another. A warrior art should enthusiastically adopt superior methods of developing individual fighting skill wherever they are found. Throughout history, successful military organizations have consistently incorporated useful techniques from rivals, allies, and civilian specialists (Keegan, 1976). What must remain constant is not the technique itself, but focus on the adaptive problem the system is organized to solve. Every borrowed method should ultimately be judged by one question: does it make the coalition more effective?

This perspective also resolves an apparent paradox. As civilization became more specialized, the individual fighting arts often surpassed the warrior arts in technical refinement within particular disciplines. This should not be surprising. Specialists almost always outperform generalists within their chosen fields. The military has every reason to learn from those specialists. It must never, however, mistake specialization for completeness. The broader requirements of the warrior art remain because the adaptive problem remains. Soldiers are still required to fight as members of coalitions rather than as isolated individuals (Henrich, 2016).

The functional classification proposed in this paper is therefore intended neither to rank nor to diminish the various martial traditions. Warrior arts, individual fighting arts, and developmental arts each represent successful solutions to different adaptive problems. Each has produced remarkable achievements within its own domain. Confusion arises only when the standards appropriate to one category are imposed upon another. Once the organizing purpose of a system is understood, many long-standing disagreements within the martial arts community become matters of classification rather than contradiction.

The same principle extends far beyond the martial arts. Throughout this paper, the central argument has been that culture repeatedly recruits ancient behavioral systems to solve new adaptive problems. Behaviors, institutions, and traditions can therefore be understood only by first asking what problems they evolved to solve. The martial arts provide an unusually clear illustration of this process because their evolution has been well documented while their purposes have repeatedly changed and many of their outward forms remained remarkably similar.

Conclusion

The martial arts are often treated as collections of techniques inherited from different cultures and historical periods. This perspective is understandable, but it obscures the more important question. Techniques are products of a deeper process. They emerge because they solve particular problems. As those problems change, the techniques, methods, organizations, and cultures surrounding them change as well.

Viewed in this way, the history of the martial arts reflects a much broader pattern in both biological and cultural evolution. Predator-prey interactions produced the earliest behavioral systems associated with violence. Competition within the social hierarchy produced ritualized forms of conflict that reduced the costs of repeated competition among members of the same species. Coalitionary competition built upon both of these ancient systems, preserving internal competition while reusing predator-prey behaviors in conflicts between groups. Human culture then recruited these inherited behavioral systems, organizing them into warrior traditions capable of producing disciplined fighting coalitions.

The warrior arts emerged as practical solutions to this coalitionary problem. Their purpose was never simply to produce better individual fighters. It was to prepare individuals to function effectively within groups engaged in violent competition with other groups. As civilization became increasingly specialized and warfare ceased to dominate the lives of most people, those arts naturally diversified. Some evolved into highly refined systems of individual combat. Others became vehicles for physical development, recreation, education, or personal cultivation. The technical ancestry often remained visible, but the adaptive problems they addressed became increasingly distinct.

Recognizing this process helps explain many of the persistent disagreements within the modern martial arts community. Systems are frequently judged according to standards they were never intended to satisfy. A military combatives program is criticized for failing to resemble a competitive fighting academy. A developmental art is dismissed because it does not produce elite fighters. A combat sport is expected to solve tactical problems that belong to warfare rather than individual competition. In each case, the error lies not in the art itself but in misunderstanding the purpose for which it exists.

The functional classification proposed in this paper is intended to reduce that confusion. Warrior arts, individual fighting arts, and developmental arts should not be understood as competing philosophies or successive stages of improvement. They represent different solutions to different adaptive problems. Their methods, cultures, and standards of excellence follow naturally from those purposes. Appreciating those differences allows each category to be understood on its own terms while encouraging the thoughtful exchange of techniques and ideas among them.

Modern Army Combatives illustrates the continuing relevance of this perspective. It benefits enormously from the technical advances produced by the individual fighting arts, particularly through the use of live training and competition. At the same time, it must remain organized around the needs of the fighting coalition rather than the ambitions of individual competitors. Its success therefore depends not upon rejecting the individual fighting arts, but upon recruiting their technical advances in service of the larger cultural purpose for which warrior arts evolved: preparing individuals to become effective members of a fighting coalition.

The broader lesson extends well beyond the martial arts. Human culture rarely creates entirely new motivational systems. Instead, it repeatedly recruits ancient biological ones, directing them toward purposes that evolution alone could never specify. Competition for social position becomes honor. Coalition loyalty becomes military discipline. Ancient predator-prey behaviors become military tactics. Purpose determines organization. When the adaptive problem changes, institutions change with it, preserving what remains useful while reorganizing inherited behaviors around new cultural purposes. The martial arts are therefore not merely systems of fighting. They are cultural institutions built upon behavioral architectures whose origins extend hundreds of millions, and in some cases more than a billion, years into the past. Understanding them requires understanding both biology and culture, and the continuing partnership between them.

For that reason, the first question we should ask of any martial system is not what techniques it teaches or from which tradition it descends. The more fundamental question is the one that has guided this paper from the beginning:

What problem was it created to solve?

Only after answering that question can its techniques, its methods of instruction, its culture, its standards of excellence, and ultimately its place within the broader history of the martial arts be fully understood.
