Blueshirts

The Army Comrades Association (ACA), later named the National Guard and better known by the nickname The Blueshirts (Irish: Na Léinte Gorma), was an Irish extra-parliamentary security organisation active in the 1930s. It consisted largely of former members of the Irish Republican Army who were pro-Treaty during the Irish Civil War. The purpose of the organisation was to provide physical protection for political groups such as the Cumann na nGaedheal from intimidation by the anti-Treaty IRA.
