Need one more Fold3 look-up. I promise this is the last one! [View all]

I thought I had all the info on a service member, but I am falling short.

My former neighbor -

James Waldo Kidder
b. 06 Jul 1922, Ft. Collins, Larimer, Colorado, USA
d. 21 Aug 1987, Escondido, San Diego, California, USA

I know he was in the military from 1942 through 1945, and according to his granddaughter, he served stateside.
The one item I could find on him, on Ancestry.com, says he was "AC / U.S. Army.'
His granddaughter says he was in the Air Force. I don't know a thing about the military.
So I am trying to find out which branch he really served in, and if at all possible,
his rank when he was discharged.

If anyone can help, I would SO appreciate it. He is going to be honored in a veterans memorial being built where he
lived at the time he passed away. I want to make sure I am putting in the correct info for him.

Thank you ahead of time!
