No longer a limited military tactic, guerrilla warfare has political and economic consequences that can be more dangerous than the armed force employed. Guerrilla warfare is an open sore that annoys today, is a nuisance tomorrow, weakens in a month, and may cause death if not treated properly. Guerrilla warfare may be waged in the Malayan jungle, in the rear areas of Korea—or on a college campus or the councils of a labor union. The technique is the same; the end is the same.
What we now call guerrilla warfare is as old as mankind. In a thousand campaigns an invaded and overrun country has been able to keep alive the spark of national feeling by the actions of a few brave men, usually operating in mountain or forest land. These irregular bands were able to compensate for lack of numbers and military skill by superior mobility and knowledge of the countryside. By attacking small groups of the enemy under surprise conditions they achieved local success, though they seldom achieved any lasting results. Such men found a place in the legends of many lands, but they made small impression in military history.
