Guerilla warfare
Guerrilla warfare is a form of irregular warfare in which a small group of combatants such as armed civilians (or "irregulars") use military tactics including ambushes, sabotage, raids, petty warfare, the element of surprise, and extraordinary mobility to dominate a larger and less-mobile traditional army, or strike an invulnerable target, and withdraw almost immediately.
The strategy and tactics of guerrilla warfare tend to focus around the use of a small, mobile force competing against a larger, more unwieldy one. The guerrilla focuses on organizing in small units, depending on the support of the local population, as well as taking advantage of terrain more accommodating of small units.
Tactically, the guerrilla army would avoid any confrontation with large units of enemy troops, but seek and eliminate small groups of soldiers to minimize losses and exhaust the opposing force. Not limiting their targets to personnel, enemy resources are also preferred targets. All of that is to weaken the enemy's strength, to cause the enemy eventually to be unable to prosecute the war any longer, and to force the enemy to withdraw.
It is often misunderstood that guerrilla warfare must involve disguising as civilians to cause enemy troops to fail in telling friend from foe. However, this is not a primary feature of a guerrilla war. This type of war can be practiced anywhere there are places for combatants to cover themselves and where such advantage cannot be made use of by a larger and more conventional force.
Communist leaders like Mao Zedong and North Vietnamese Ho Chi Minh both implemented guerrilla warfare giving it a theoretical frame which served as a model for similar strategies elsewhere, such as the Cuban "foco" theory and the anti-Soviet Mujahadeen in Afghanistan.
Mao Zedong summarized basic guerrilla tactics at the beginning of the Chinese "Second Revolutionary Civil War" as: "The enemy advances, we retreat; the enemy camps, we harass; the enemy tires, we attack; the enemy retreats, we pursue."[3]:p. 124 At least one author credits the ancient Chinese work The Art of War (dating from at least 200 BC) with providing instruction in such tactics to Mao.:pp. 6–7

While the tactics of modern guerrilla warfare originate in the 20th century, irregular warfare, using elements later characteristic of modern guerrilla warfare, has existed throughout the battles of many ancient civilizations but in a smaller scale. This recent growth was inspired in part by theoretical works on guerrilla warfare, starting with the Manual de Guerra de Guerrillas by MatÃas Ramón Mella written in the 19th century and, more recently, Mao Zedong's On Guerrilla Warfare, Che Guevara's Guerrilla Warfare and Lenin's text of the same name, all written after the successful revolutions carried by them in China, Cuba and Russia respectively. Those texts characterized the tactic of guerrilla warfare as, according to Che Guevara's text, being "used by the side which is supported by a majority but which possesses a much smaller number of arms for use in defense against oppression".
