Defination of Guerilla Warfare

Guerrilla warfare is a method of unconventional combat by which small groups of combatants attempt to use mobile and surprise tactics (ambushes, raids, etc) to defeat a foe, often a larger, less mobile, army. Typically the smaller guerrilla army will either use its defensive status to draw its opponent into terrain which is better suited to the former or take advantage of its greater mobility by conducting surprise attacks at vulnerable targets, often deep in enemy territory.. the main objective of this kind of warfare is to lower the enemy morale, undermining authority, holding off an invasion and to make the cost of maintaining an army in hostile territory very high through a low intensity confrontation. it isnt used to define offensive actions
huns were invaders who used surprise attacks and feigned retreats on a tactical rather than strategic level. they besieged settlements and occupied territories.. whereas the main feature of guerrilla warfare is withdrawal after completing an objective.
the pioneers of guerrilla warfare would be surprisingly the roman republic during the second punic war. The romans applied the Fabian strategy under the Roman dictator Fabius Maximus after facing disastrous defeats in pitched battles. full-scale pitched campaigns were exchanged for small-scale skirmishes, sieges, sabotage attempts, assassinations and raiding parties. The Romans set aside the typical military doctrine of crushing the enemy in a single battle and initiated a successful, albeit unpopular, war of attrition against the Carthaginians that lasted for 14 years.
