Almost immediately upon entering service, French forces commenced active combat operations using their fledgling Alouette II fleet; the type being placed into heavy use in the Algerian War, during which it made valuable contributions to France's activities in the theatre. When used as a troop-transport, up to four fully equipped soldiers could be airlifted at a time. Additionally, a number of Alouette IIs were modified to become what has been argued by some to have been the world's first helicopter gunships; in this capacity, it would have been typically armed with Nord Aviation-built SS.10 or SS.11 anti-tank missiles.
