Rifleman in AAF in WWII
Would a "Rifleman 745" have been assigned to a bomb squadron in the Army Air Force during WWII? My father had that MOS and I had always believed that he served in the Infantry with Army Ground Forces. However his separation papers shows him as a Rifleman-745 in the 441st Bomb Squad of the 320th Bomb Group. Can anyone exlain what a Rifleman would be doing in the AAF?
