These troops, otherwise known as the Commandos, serve with the motto “Luck Protects the Bold” and are often heard singing their war cry. This special forces unit was originally formed to act as a counter-guerrilla force in the Portuguese Colonial War. As most training and selection courses for special forces units go, the Portuguese Commandos have to prove their physical and mental might in order to make the cut. The training uses what’s called psychological training to test the willpower of recruits whereby none of the soldiers are told what the physical training will entail, but have to preserve until the very end, however long that may be.
