The primary function of Spetsnaz troops in wartime was infiltration/insertion behind enemy lines (either in uniform or civilian clothing), usually well before hostilities are scheduled to begin and, once in place, to commit acts of sabotage such as the destruction of vital communications logistics centers, and the possible assassination of key government leaders and military officers.[citation needed] Spetsnaz GRU operatives would have to complete training that included the following: weapons handling, rappelling, explosives training, marksmanship, counter-terrorism, airborne training, hand-to-hand combat, climbing (alpine rope techniques), diving, underwater combat, long-range marksmanship, emergency medical training, and demolition.
