Fireforce is a variant of the tactic of vertical envelopment of a target by helicopter-borne infantry developed by the Rhodesian Security Forces. Fireforce counter-insurgency missions were designed to trap and eliminate ZANLA and ZIPRA insurgents before they could flee by reacting to ambushes, farm attacks, or OP sightings, and could also be called in by trackers or patrols who made contact with the enemy and called for reinforcements. It was first deployed in January 1974 and saw its first action a month later on the 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 and one Dakota (colloquially called "Paradaks"), with a command/gunship helicopter and a light attack aircraft in support. One of the advantages of the Fireforce was its flexibility, as all that was need was a reasonable airstrip.
Nice, you don't see this footage often.
