Fireforce is a variant of the military tactic of vertical envelopment of a target by helicopter-borne and parachute infantry developed by the Rhodesian Security Forces during the Rhodesian Bush War. Regiments involved included the Rhodesian Light Infantry or RLI (all-European, i.e. white), the Rhodesia Regiment (African, but with white officers), the Rhodesian Special Air Service or SAS (white) and the Selous Scouts (both European and African), assisted by the Rhodesian Air Force. the Fireforce counter-insurgency missions were designed to trap and eliminate Zimbabwe African National Liberation Army and Zimbabwe People's Revolutionary Army insurgents before they could flee.
Fireforce reacted to enemy ambushes, farm attacks, or observation post (OP) sightings, and could also be called in by trackers or patrols who had made contact with the enemy and then called for reinforcements. Fireforce was first deployed in January 1974, and saw its first action a month later on 24 February 1974.
Fireforce was an operational assault or response usually composed of a first wave of 32 soldiers carried to the scene by three helicopters (G-Cars) and one Dakota (Paradaks), with a command/gunship helicopter (K-Car) and a light attack aircraft in support (Lynx). One of the advantages of the Fireforce was its flexibility, as all that was needed was a reasonable airstrip.
