At home my maternal grandmother worked in an aluminum mill, my great-grandfather was an air raid warden. A great-uncle was previously enlisted in the navy but honorably discharged due to illness, otherwise he would have served. My paternal grandfather's knee would occasionally pop out, otherwise he would have served as well, but he was a farmer so he undoubtedly did his part anyhow.
A great uncle on my father's side was an Army medic when the Philippines were invaded, fate unknown other than being KIA, its probable he ended up in the Bataan death march from some family research though.
My maternal grandfather was drafted mid-1941, and trained in Louisiana before the war. He was initially trained as a machine gunner, but from what I can learn from newspaper articles my grandmother saved, it seems him and a few other soldiers formed an impromptu dance band, which became the 32nd division dance band. He was in the 32nd division, which, after war was declared, was deployed to Australia to defend against the anticipated Japanese invasion, and eventually became the longest serving unit in the US military during the war, also the most decorated (my grandfather was awarded the Bronze Star himself). He was personally in the New Guinea and Philippines campaigns, but traveled extensively due to putting on shows for the troops. The band provided the ceremonial music for the reestablishment of the Philippine Republic as well.
He did not just play music though, as he would be on guard and KP duty, and, I suspect, would probably bring supplies to the front and bring wounded back, the historic role of musicians in battle when not playing. He never spoke of the war, apart from mentioning "washmachine Charlie," a nickname for a rickety engine Japanese patrol plane which would fly over at night and drop small bombs to harass the GI's, so he obviously witnessed grisly stuff; we know what we do from newspaper clippings. He was shipped back in July (?) of 1945 (he weighed only 90lbs) and married my grandmother that September.
