Irregular warfare (IW) is defined in United States joint doctrine as "a violent struggle among state and non-state actors for legitimacy and influence over the relevant populations" and in U.S. law as "Department of Defense activities not involving armed conflict that support predetermined United States policy and military objectives conducted by, with, and through regular forces, irregular forces, groups, and individuals." In practice, control of institutions and infrastructure is also important. Concepts associated with irregular warfare are older than the term itself.
Irregular warfare favors indirect warfare and asymmetric warfare approaches, though it may employ the full range of military and other capabilities in order to erode the adversary's power, influence, and will. It is inherently a protracted struggle that will test the resolve of a state and its strategic partners."Irregular Warfare (IW) Joint Operating Concept (JOC)", Version 1.0, United States Department of Defense, 27 February 2009 "US Irregular Warfare (IW) Analysis Workshop", Military Operations Research Society (MORS), 11 September 2007 ."Irregular Warfare (IW)", DoD Directive 3000.07, United States Department of Defense, 1 December 2008 "Quadrennial Roles & Missions (QRM) Review Report", United States Department of Defense, January 2009 "Irregular Warfare", Doctrine Document 2-3, United States Air Force, 1 August 2007
The term "irregular warfare" in Joint doctrine was settled upon in distinction from "traditional warfare" and "unconventional warfare", and to differentiate it as such; it is unrelated to the distinction between "regular" and "irregular forces".
Terminology
Early usage
One of the earliest known uses of the term "irregular warfare" is Charles Edward Callwell's classic 1896 publication for the United Kingdom War Office, Small Wars: Their Principles and Practices, where he noted in defining 'small wars':
A similar usage appears in the 1986 English edition of Modern Irregular Warfare in Defense Policy and as a Military Phenomenon by former Nazi officer Friedrich August Freiherr von der Heydte. The original 1972 German edition of the book is titled Der Moderne Kleinkrieg als Wehrpolitisches und Militarisches Phänomens. The German word "Kleinkrieg" is literally translated as "small war". The word "irregular," used in the title of the English translation, seems to be a reference to non-regular armed forces as per the Third Geneva Convention.
Another early use of the term is in a 1996 Central Intelligence Agency (CIA) document by Jeffrey B. White. Major military doctrine developments related to IW were done between 2004 and 2007 as a result of the September 11 attacks on the United States. A key proponent of IW within US Department of Defense (DoD) is Michael G. Vickers, a former paramilitary officer in the CIA. The CIA's Special Activities Center (SAC) is the premiere American paramilitary clandestine unit for creating and for combating irregular warfare units.Stone, Kathryn & Williams, Anthony R., All Necessary Means: Employing CIA operatives in a Warfighting Role Alongside Special Operations Forces, United States Army War College (USAWC), 7 April 2003. For example, SAC paramilitary officers created and led successful irregular units from the Hmong tribe during the war in Laos in the 1960s,Shooting at the Moon: The Story of America's Clandestine War in Laos, Steerforth Press, , 1996. from the Northern Alliance against the Taliban during the war in Afghanistan in 2001,Woodward, Bob, Bush at War, Simon and Schuster, , 19 November 2002. and from the Kurdish Peshmerga against Ansar al-Islam and the forces of Saddam Hussein during the war in Iraq in 2003.Tucker, Mike & Faddis, Charles, Operation Hotel California: The Clandestine War inside Iraq, The Lyons Press, , 2008.Woodward, Bob, Plan of Attack, Simon and Schuster, , 2004.Covert Action: Title 10, Title 50, and the Chain of Commanaad
Other definitions
IW is a form of warfare that has as its objective the credibility and/or legitimacy of the relevant political authority with the goal of undermining or supporting that authority. IW favors indirect approaches, though it may employ the full range of military and other capabilities to seek asymmetric approaches in order to erode an adversary's power, influence, and will."Irregular Warfare Special Study," United States Joint Forces Command Joint Warfighting Center, 4 August 2006 IW is defined as a violent struggle among state and non-state actors for legitimacy and influence over the relevant population(s). IW involves conflicts in which enemy combatants are not regular military forces of nation-states."Quadrennial Defense Review Report", United States Department of Defense, 6 February 2006 IW is "war among the people" as opposed to "industrial war" (i.e., regular war).
Activities
Activities and types of conflict included in IW are:
Asymmetric warfare Civil-military operations (CMO) Colonial war Foreign internal defense (FID) Guerrilla warfare (GW) Insurgency/Counter-insurgency (COIN) Law enforcement activities focused on countering irregular adversaries Military Intelligence and counter-intelligence activities Stabilization, Security, Transition, and Reconstruction Operations (SSTRO) Terrorism/Counter-terrorism Transnational criminal activities that support or sustain IW: narco-trafficking Illicit arms trafficking illegal financial transactions Unconventional warfare (UW)
According to the DoD, there are five core activities of IW: Counter-insurgency (COIN) Counter-terrorism (CT) Unconventional warfare (UW) Foreign internal defense (FID) Stabilization Operations (SO)
Modeling and simulation As a result of DoD Directive 3000.07, United States armed forces are studying irregular warfare concepts using modeling and simulation."U. S. Army Enhancement of Irregular Warfare Modeling & Simulation", United States Army Modeling and Simulation Office, 24 February 2009 ."MORS Workshop Irregular Warfare (IW) II Analysis Workshop", Military Operations Research Society, 3–6 February 2009 Cragg, Lt. Jennifer, "Behavior Studies May Improve Irregular Warfare Techniques", American Forces Press Service, 20 April 2009
Examples
Nearly all modern wars include at least some element of irregular warfare. Since the time of Napoleon, approximately 80% of conflict has been irregular in nature. However, the following conflicts may be considered to have exemplified by irregular warfare:
Afghan Civil War Algerian War American Indian Wars American Revolutionary WarAccording to the definition of "regular forces," which came long after the American Revolutionary War, the American forces did not meet the following criteria at all times during the American Revolutionary War: having a fixed distinctive emblem recognizable at a distance carrying arms openly conducting operations in accordance with the laws and customs of war
Nonetheless, in terms of modern international humanitarian law, which was also developed much later than the American Revolutionary War, the American forces formed part of the armed forces of a party to an armed conflict but not belonging to that party's regular forces (since the United States of America did not exist and hence could not have had regular forces; the American forces were an insurgency at least until 1776) and operating in or outside of their own territory even if the territory is under occupation.
American forces did become regular forces but cannot be considered regular forces during the entire period of the war. For example, the American flag was established in 1777, two years after the war started (1775). Also, there were great disparities between the American and British forces. It was not until France started to assist American forces (1778) that the disparity started to be narrowed. Conflict during the disparity surely counts as asymmetric warfare. Also, the Boston Tea Party (1773) can be viewed as guerrilla tactics. At the very least, a good portion of the American Revolutionary War should be counted as IW, although the entire war being counted as IW is controversial. However, since more than a half the war was fought as the American Revolutionary War, it is thought that it is safe to classify it as IW even though that the American forces acted in all respects as regular forces towards the end of the conflict.

Wargames and exercises
There have been several military wargames and military exercises associated with IW, including:
Unified Action, Unified Quest, January 2010 Tri-Service Maritime Workshop, Joint Irregular Warrior Series war games, Expeditionary Warrior war game series, and a December 2011 Naval War College Maritime Stability Operations Game focused specifically on stability operations in the maritime domain conducted by the Naval Service.
