Portuguese paratroopers or “paras” began as a stepchild of the army and found a home in the Portuguese Air Force in 1955. Initially, the post-World War Two Portuguese Army seemed to have had mixed emotions about the need for elite, special-purpose forces that operated in small units with the attendant flexibility and elevated lethality. Shock troops have been traditionally controversial, and even the vaunted military theorist Baron Karl von Clausewitz saw little point in them. The history of the paras in the Portuguese Army is illustrative of this ambivalent view. Nevertheless, in a “war of the weak” in which insurgents avoid government strengths and exploit its vulnerabilities using agility, deception, and imagination, such small, crack government units are particularly well suited to counterinsurgency operations.
