GI bride:
(plural: ‘GI brides‘; pronunciation: the letter ‘g’ in this word rhymes with the letter ‘j’ in the word “judge”)

(government issue kit)
‘G I’, in this context, means “government issue” or “galvanised iron — the iron things the soldiers used”, the nick name given to the American soldiers in a foreign country during war, especially during World War II (next entry). ‘Bride‘ is a woman who is just married or is going to be married.
a woman who married a US soldier, who was called a GI Joe, when he was in her home country, especially in World War II;
a war bride,

a GI bride with her GI Joe
e.g.
Jane who passed away recently was one of the first wave of GI brides from Europe.
There were stories about young women who married GI Joes on the sole purpose of emigrating to the USA, during and after the World War II.
Strangely enough most of the GI brides, especially those from Europe, in the US stayed more loyal to their Americans husbands than the American girls to their American husbands.
