Portugal became the first country to use the Alouette III in combat during the Overseas War, where it was operated extensively by the Portuguese Air Force in the Portuguese overseas territories until the end of the war and the subsequent withdrawal of all Portuguese troops from Africa in 1974 and 1975. Helicopters, particularly the Alouette III, became an important asset during the conflict in counter-insurgency operations, as they allowed for rapid deployment of ground forces, as well as close air support, and delivery of supplies to remote areas and the ability to withdraw wounded troops during combat.
