I have a picture of my grandfather's uncle after he enlisted, and I'm trying to figure out what I assume to be his unit patch signifies. The patch I'm referencing is the diamond with the black bar above his rank. The picture was labeled WWI, but it appears to be a WWII uniform. Here's the picture: https://i.imgur.com/N7o4dq8.jpg
The patch is for the 1st Corps Area, which controlled non-combat military affairs of the U.S. Army in the states of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. On July 22, 1942, Corps Areas were transferred to the jurisdiction of the Army Service Forces and renamed Service Commands.
