Fourth Generation Warfare
March 23, 2005
It has been said that "fourth generation warfare" (4GW) includes all forms of conflict where the other side refuses to stand up and fight fair. Smart commanders throughout history, however, have tried to deceive, trick, and confuse their opponents. Is anything really new?
The answer begins by examining how 4GW literature uses the term, "generation." Specifically, it refers to the world since the mid-17th Century, when firearms began to dominate the battlefield and when nation-states began to exercise a legal monopoly on the use of armed force.
4GW Case Studies:
al-Qa'ida / Afghanistan
al-Aqsa Intifada
That world is breaking down. We appear to be returning to the situation that characterizes most of human experience, where both states and non-states wage war. In 4GW, at least one side is something other than a military force organized and operating under the control of a national government, and one that also transcends national boundaries. For a graphical depiction of how the "generations" evolve, please download The Evolution of Conflict (169 KB PowerPoint slideshow.) Note that as with human generations, several may be alive and functioning simultaneously. The word "generations," though, is just an analogy to help gain new insights, and it is wise not to push it too far.
One way to tell that 4GW is truly new is that we don't even have a name for its participants—typically dismissing them as "terrorists," "extremists," or "thugs."
Name calling, though, is not often an effective substitute for strategy.
If we look at the development of warfare in the modern era, we see three distinct generations … Third generation warfare was conceptually developed by the German offensive in the spring of 1918 … Is it not about time for the fourth generation to appear? Lind, Nightengale, Wilson, et. al., Marine Corps Gazette, October 1989
The attacks on the Pentagon and World Trade Center dispelled the notion that 4GW is simple "terrorism." But one can sympathize with our political and military leaders, because 4GW is a strange form of warfare, one where military force plays a much smaller (though still critical) role than in earlier generations, supporting initiatives that are more political, diplomatic, and economic.
As important as finding and destroying the actual combatants, for example, is drying up the bases of popular support that allow them to recruit for, plan, and execute their attacks. Perhaps most odd of all, being seen as too successful militarily may create a backlash, making the opponent's other elements of 4GW more effective.
The authors of the first paper on the subject captured some of this strangeness when they predicted:
The distinction between war and peace will be blurred to the vanishing point. It will be nonlinear, possibly to the point of having no definable battlefields or fronts. The distinction between 'civilian' and 'military' may disappear.
However it develops, fourth generation warfare is real war. The aim of its participants, as in all generations, is to impose change on its opponents. For a variety of reasons, sketched below and covered in detail in the papers on this site, most of the techniques that will be used in 4GW played peripheral roles in earlier generations of warfare and undoubtedly predate history itself. Today, two of the most frequently mentioned of these techniques are terrorism, as we have seen, and guerrilla warfare / low intensity conflict (LIC.)
Is 4GW Just Another Term for "Terrorism"?
The more the terror, the greater our victories. – White Russian General Kornilov, 1917
We can't expect to get anywhere unless we resort to terrorism. – Lenin, 1918
"Terrorism" (defined as seemingly gratuitous violence against civilians or non-combatants) has been a part of all generations of war. Until recently, in fact, most wars killed many more civilians than military and not all of this was accidental - recall the Rape of Nanking, the London Blitz, and the firebombing of Dresden. As 4GW blurs any distinction between "military" and "civilian," we can expect more activities that the general population will regard as terrorism. In other words, there may be more terrorism in 4GW, but it is not unique to nor defined by these attacks.
Is 4GW Just Another Term for "LIC"?
... members of native forces will suddenly become innocent peasant workers when it suits their fancy and convenience. - USMC Small Wars Manual, 1940
Similarly, because practitioners of 4GW will be transnational groups without territorially-based armies, much of their activity will probably resemble "guerilla warfare" or "low intensity conflict." These highly irregular practices have enabled groups that are weak, militarily, to defeat larger, stronger forces, and they have deep roots in the history of war. The word "guerilla" itself, for example, dates back nearly 200 years to Napoleon's occupation of Spain.
Until recently, however, such "special" operations more often harassed than decided—"sideshows" (as T. E. Lawrence once termed them) in wars fought mainly along 1st, 2nd, or 3rd generation lines. Examples could include operations by colonial militias and guerillas during the Revolutionary War, Nathan Bedford Forrest's cavalry raids, partisans during WWII, and the tactics practiced in the early stages of most "national liberation" wars in the 20th Century, including Vietnam. In all of these, conventional forces delivered the culminating blows.
A premise of 4GW is that the world itself has changed, so that terrorism and guerilla warfare—and other elusive techniques that are still being invented—are now ready to move to center stage. These techniques focus not so much on the enemy's military capabilities (although these may be attacked) but directly against the will of the enemy to continue the war. All of the operations by a 4GW force must support this goal. In its most fully developed form, there may be no real "battles" at all, as was virtually the case in the Sandinista take-over of El Salvador in 1979.
There was a 4GW component to the Vietnam War—the campaign by North Vietnam, of which the Viet Cong insurgency formed a key part, to turn US public opinion against the war. Once this was accomplished, and the US withdrew, the South could be finished off by conventional means, as is not unusual for either the final phase of a traditional guerrilla effort or of a fourth generation war. Similarly, the goal of the mujaheddin in Afghanistan was not to defeat the Red Army in some decisive battle, but to persuade the Soviet leadership to withdraw it, and al-Qa'ida appears to have achieved similar results in Spain.
To summarize, fourth generation warfare appears to be evolving along two complementary lines:
One of the opponents is something other than the armed forces of a state;
The focus (Schwerpunkt) of the non-state player's operations is the process, whatever it may be, within the state for deciding to continue the conflict.
Unlike Clausewitzian warfare, that is, a conflict between opposing wills much like a boxing match between states, 4GW more resembles a boxer versus a viral infection. Terrorism and LIC are two of the more common techniques, but there is no reason why conventional weapons and tactics could not also find a place—a submarine, for example, was recently discovered under construction by narco-trafficking groups in South America—and as been noted, fourth generation wars often culminate in a final conventional push ("Mao Phase III") to subdue the remaining military forces of the state.
It would be a mistake and, in fact, a goal of our opponents might be to encourage this mistake, if we were to focus on the techniques and not the nature of 4GW itself. As Col T. X. Hammes eloquently argues in "The Evolution of War: The Fourth Generation," social and political changes are driving this evolution—a theme he develops in his important new book, The Sling and The Stone.
You can construct your own list of what is different about today's world than that of, say, 1960. Here are some ideas to get you started:
explosion in drug trafficking, with associated money flows and corruption to the extent that trafficking organizations are the de facto governments in a growing number of areas
worsening income inequities combined with a general decline in standards of living in many Third World countries, particularly in Africa and Central/South America
continued exponential increase in the world population
a growing "demographic youth bulge" in Third World countries, where un- / underemployment is already severe [cited in recent CIA testimony]
escalating sectarian violence as evangelizing religions (Christianity, Islam, Hinduism, etc.) clash over influence in rapidly growing Third World countries
survival of non-representative governments in the Third World that use religious and ethnic animosities and anti-American sentiments to distract from their own corruption and economic mismanagement
insertion & maintenance of a largely Christian American Army into the heart of the Muslim Middle East
accelerating AIDS epidemic in parts of the Third World [~30% of adults in Botswana are HIV-positive]
rise of Third World mega cities with populations exceeding 20 million
growth of worldwide connectivity (CNN and the Internet, for example)
ease of global transportation (24 hours between any two points)
increasing scarcity of arable land and water
increasing world demand for petroleum as China and India increase their consumption
disintegration of the Soviet Union and continued instability in that region
end of the bipolar world order and of the interpretation of events through a Cold War filter
ready availability of small arms and other weapons from the end of the Cold War
growing use of pre-adolescent children as combatants
resurgence of violent ethnic and ideological groups (e.g., Rwandan Interahamwe, and of course al-Qa'ida), which are becoming increasingly transnational
safe havens for these groups in areas of Africa, Asia, and South America where any effective government (even if corrupt and incompetent) is lacking
beginning of cooperation between transnational ideological groups and traditional criminal organizations such as narcotrafficking cartels
continued growth in wealth and influence of multinational corporations that sometimes have incentives to perpetuate corrupt, non-democratic regimes
emergence of the US as the only conventional / economic superpower and the inevitable resentment this causes
If these or similar factors are indeed driving the evolution of conflict, then solutions must lie primarily in their arenas, that is, within the realms of economics, diplomacy, and law-enforcement. Military force will play a smaller role, performing specific tasks to solve problems that are intractable through other means. A coherent "grand strategy" is needed to ensure that military (destructive) actions harmonize with our overall objectives and do not undermine the public support needed to prosecute a fourth generation war to its successful conclusion. In grand strategy, the carrot is as important as the stick, and alliances are critical—factors which should favor the United States and its allies in the 4GW against al-Qa'ida and those who support similar ideologies.
Technology is not unimportant, and may provide options, but the fact is that lack of suitable technology cannot explain our less-than-stellar track record in fourth generation warfare.
Editor's Note: Any discussion of 4GW, since it involves conflicts of culture and religion, is likely to generate a high degree of emotion. In the articles that follow, some may find the authors' views to be simplistic or even offensive. For the record: Defense and the National Interest does not endorse any political, cultural, or religious viewpoint. These papers, however, raise many important questions about the nature of future conflict, and we are publishing them to stimulate thought and debate.

Joint Inquiry Staff Statement on September 11.
Asymmetries and Consequences, Col Richard Szafranski, USAF, Ret. National leaders have insisted, correctly in our view, that we must take the offensive against terrorism. With few terrorist havens remaining to bomb, however, and with the majority of active al-Qa'ida operatives likely already in the US, western Europe, or in countries we are not going to attack, what does this mean? In this paper presented at the Global Strategy Conference in Priverno, Italy, May 2002, Richard Szafranski offers some concrete answers. Ultimately we can prevail: "My belief," he writes, " is that the September 11, 2001, attacks were unwise. Monumentally unwise." (55KB PDF file.)

Fourth Generation Warfare: What Does it Mean to Every Marine? Col Michael D. Wyly, USMC, Ret. The source of our advantage over fourth generation opponents lies not in the superiority of our technology or even of our ideology. In this prescient paper, Mike Wyly maintains that it lies in the very bedrock of our society - the Constitution. Those would would wage 4GW must read, ponder, and understand this remarkable document, to which all members of the military have sworn to protect from all enemies, foreign and domestic. [As a colleague of then-Commandant Al Gray, Col Wyly was one of the prime movers behind the Marines' adoption of third generation - maneuver - warfare in the late 1980s.]

For those new to 4GW, this is probably the best place to start: "The Evolution of War: The Fourth Generation," by LtCol Thomas X. Hammes, USMC. LtCol Hammes observes that "generations" of warfare are not defined primarily by the technology employed since, to some degree, each generation can use any available technology. Rather, generations are better categorized by political, social, and economic factors. After buttressing his case with examinations of China, Vietnam, Nicaragua, and the West Bank (Intifada I), LtCol Hammes concludes this important paper with the prediction that, "By using fourth generation techniques, local antagonists can change the national policy of Western democracies. Then once the Western forces have gone, they can continue to pursue their local objectives using earlier generation techniques." Originally published in the Marine Corps Gazette, September 1994.
