G I Joe:
(also G I; plural: ‘GI Joes‘; pronunciation: the letter ‘g’ in this word rhymes with the letter ‘j’ in the word “judge”)

(a government issue)
a nickname for a typical US soldier, especially in World War II,

a GI Joe of WW II with his GI bride
Every GI Joe in the World War II had a small metal tag called dog tag on which the name, serial number, company or division he belonged to and the address in the States so that in case of death, the next of kin would be informed.
Most of the GI Joes returned to their homeland after the war with not only the battle experience and medals but also a wife, called ‘GI Bride’!
This phrase and the stories associated with GI Joes is so popular that there are several films, TV serials, cartoons, toys and even survival kits are named after them.
