Can anybody tell me anything about this unit photo (no AAF stamp on the back) My grandfather is in the picture. I know that he was in the AAF based on a uniformed photo that I have. He was discharged in a Engineer Combat Battalion. I have several photos of his AAF time that were taken in Europe between Aug. 44- Feb. 45.(stamped by AAF). photo has water cooled .50 cal Browning's and soldiers are hold M1 carbines. Any ideas. Not a lot to go on I know.
