The history of the Portuguese commandos began on 25 June, 1962, when, in Zemba (Northern Angola), the first six groups of those that would be the predecessors of the commandos, were formed. For the preparation of these groups, the "CI 21 – Centro de Instrução de Contraguerrilha" (Counter-Guerrilla Instruction Centre) was created, commanded by Lieutenant-Colonel Nave, and had as instructor, the photographer and former French Foreign Legion Sergeant, the Italian Dante Vachi, with experience in the Indochina and Algerian wars.
