The second company had as its destination Mozambique, commanded by Captain Jaime Neves. The organisation and organisational principles of the Portuguese commandos, are established in great mobility and creativity and in counter-guerrilla combat techniques, very well defined and able to support permanent innovation. The composition and organisation of the commando companies were always adapted to the circumstances and situations, although throughout the war it was possible to verify two main models, that originated what we can call light companies and heavy companies. The former were composed of four commando groups, each one with four sub-groups, constituting 80 men and with few back-up components. These companies had little capability to maintain themselves, independently, during long periods of time, because they were meant as temporary reinforcements to units in "quadrillage", like intervention forces, and received from those units the necessary support. In these companies, the mobility and flexibility were privileged, and were initially used in Guinea and Mozambique. The heavy companies had five, five-team commando groups, in a total of 125 men, together with a formation of service personnel, of about 80 men, with medics, signallers, transport soldiers and cooks. Another type of organisation was adapted to the companies of African commandos, formed in Guinea and composed of metropolitan soldiers when needed, a bit like the American special forces did in Vietnam with the "advisers". The war's evolution, the necessity that started to exist of fighting in large units in Guinea and Mozambique and to, sometimes simultaneously, conduct special and irregular actions, led to the creation of commando battalions in those two theatres. This function of mother-unit was, in Angola and since its foundation, performed by the "Centro de Instrução de Comandos" (Commando Instruction Centre), that also needed to adapt, separating the instruction activity and gathering the operational units in a base in "Campo Militar de Grafanil" (Grafanil Military Camp), near Luanda, although it was never completely independent of the operational use under a specific command. As larger commando units the "Centro de Instrução de Comandos" (Commando Instruction Center), in Angola, the "Batalhão de Comandos da Guiné" (Guinea Commando Battalion) and the "Batalhão de Comandos de Moçambique" (Mozambique Commando Battalion) were formed. Although Angola's Commando Instruction Centre was the home and it was in that centre that the main core of doctrine of use and mystique of the commandos were formed, all battalions gave instruction to their staff and formed units to intervene in the operations theatre.
