In order to improve performance, Rhodesia's Alouette II fleet was subject to extensive modifications, including changes to their refuelling apparatus, gun sights, cabin fittings, armouring, and armaments. Over time, the Rhodesian Security Forces developed an innovative deployment tactic of rapidly encircling and enveloping enemies, known as the Fireforce, for which the Alouette II served as a core component. The quick-reaction Fireforce battalions were centred at Centenary and Mount Darwin; however, a deliberate emphasis was placed on locating both rotorcraft and troops as close to a current or anticipated theatre of operations as would be feasibly possible.
