In 1976, during Operation Savannah, a need was identified for more operational special forces units and in particular units with more specialised skills. In March 1976, Major Malcolm Kinghorn formed a sub-unit specialising in amphibious operations for use in Angola during Operation Savannah. It was formed at Salisbury Island, Durban and consisted of a headquarters unit of Kinghorn and a NCO and two units of six men each and was called Charlie (C) Group of 1 Reconnaissance Commando.
