The term 'G.I.' (which may be a noun or an adjective) is used to describe a member of the U.S. Armed Forces, or items of equipment used by the Armed Forces. It is short for 'Government Issue', although some wrongly believe it to be an abbreviation of 'General Infantry'. Originally, 'G.I.' stood for 'Galvanised Iron', the material from which many items used by the Armed Forces were made.
The official title of the 'G.I. Bill' was the 'Servicemen's Readjustment Act', passed in 1944. Its object was to provide college or vocational training and financial support to returning veterans of World War II. The term 'G.I. Bill' was subsequently used to describe aid programs for both war veterans and other discharged servicemen.
