Vincent Patriarca, Italian-American aviator and mercenary (born 1914)

Vincent Joseph Patriarca, later known as Maresciallo Vincenzo Joseph Patriarca, was an Italian American notable for being one of the few United States citizens to fight for Franco's Nationalists during the Spanish Civil War, rather than in the Republican International Brigades such as the Abraham Lincoln Brigade.

A mercenary is a private individual who joins an armed conflict for personal profit, is otherwise an outsider to the conflict, and is not a member of any other official military. Mercenaries fight for money or other forms of payment rather than for political interests.
