My grandfather was in 1561 Lt AA Regt Platoon RASC from 1943 to 1945. Any info on this unit would be great. I have his service records and there are some things that mean nothing to me. For instance: 725 Coy Posted to 791 Coy RASC PR CAR & SOS this unit wef Does anyone know what some of these abbreviations are. I have some old photos and would be very interested in finding out what his unit did? I know from his service records that they left for BLA on 17/7/1944 and I have photos of Belsen and some of him in areas of Germany (near Munster and Hanover).
