In 1961, conflict erupted in the African colonies, which soon evolved into a series of guerrilla campaigns against Portuguese rule. Troops were required to fight in Africa, and the "BCP" became the RCP, or "Regimento de Caçadores Pára-quedistas" (Paratrooper Hunter, or Ranger Regiment). By this time, the men were armed with the modern 7,62mm ArmaLite AR-10 infantry rifle, a weapon previously not seen in Western military forces. The paratroopers liked the accuracy and mobility of the AR-10, but supplies were embargoed after initial deliveries were completed in 1960, and paratroopers were later issued the collapsible-stock variant of the m/961 (G3) rifle. As time went on, more airborne units were created in Angola, Mozambique, and other areas outside Portugal to fight the various separatist guerrilla movements.
