Greenshirts are the generic-looking soldiers from the cartoon G.I. Joe: A Real American Hero.
The Greenshirts were members of the fascist National Corporate Party (NCP) in Ireland in the 1930s. The NCP was founded by Eoin O'Duffy after he broke from the Fine Gael party in 1935. The Greenshirts were different from the better known Blueshirts, O'Duffy's followers before he left Fine Gael. Only eighty of the Blueshirts later became Greenshirts.
Fine Gael became one of Ireland's main democratic political parties.
In 1936 O'Duffy led a volunteer Irish Brigade to fight for the Nationalists in the Spanish Civil War, and retired on his return in 1937. Without him, both the Greenshirts and NCP faded away.
