2-43. Unconventional warfare is defined as activities conducted to enable a resistance movement or insurgency to coerce, disrupt, or overthrow a government or occupying power by operating through or with an underground, auxiliary, and guerrilla force in a denied area (JP 3-05.1). An underground is a cellular covert element within unconventional warfare that is compartmentalized and conducts covert or clandestine activities in areas normally denied to the auxiliary and the guerrilla force (ADP 3-05). An auxiliary is, for the purpose of unconventional warfare, the support element of the irregular organization whose organization and operations are clandestine in nature and whose members do not openly indicate their sympathy or involvement with the irregular movement (ADP 3-05). A guerrilla force is a group of irregular, predominantly indigenous personnel organized along military lines to conduct military and paramilitary operations in enemy -held, hostile, or denied territory (JP 3-05). Unconventional warfare operations, missions, and tasks are politically sensitive activities that involve a high degree of military risk and require distinct authorities and precise planning often characterized by innovative campaign design.
