Guerrilla warfare

Guerrilla warfare is a form of irregular warfare in which a small group of combatants, such as paramilitary personnel, armed civilians, or irregulars, use military tactics including ambushes, sabotage, raids, petty warfare, hit-and-run tactics, and mobility to fight a larger and less-mobile traditional military. Guerrilla groups are a type of violent non-state actor.

The Spanish word "guerrilla" is the diminutive form of "guerra" ("war"). The term became popular during the early-19th century Peninsular War, when the Spanish and Portuguese people rose against the Napoleonic troops and fought against a highly superior army using the guerrilla strategy. In correct Spanish usage, a person who is a member of a "guerrilla" unit is a "guerrillero" () if male, or a "guerrillera" (]) if female.

The term "guerrilla" was used in English as early as 1809 to refer to the "fighters" (e.g., "The town was taken by the guerrillas"), and also (as in Spanish) to denote "a group or band" of such fighters. However, in most languages "guerrilla" still denotes the specific style of warfare. The use of the diminutive evokes the differences in number, scale, and scope between the guerrilla army and the formal, professional army of the state.

Guerrilla warfare is a type of asymmetric warfare: competition between opponents of unequal strength. It is also a type of irregular warfare: that is, it aims not simply to defeat an enemy, but to win popular support and political influence, to the enemy's cost. Accordingly, guerrilla strategy aims to magnify the impact of a small, mobile force on a larger, more-cumbersome one. If successful, guerrillas weaken their enemy by attrition, eventually forcing them to withdraw.
Tactically, guerrillas usually avoid confrontation with large units and formations of enemy troop...
