Hi I am working on a RA soldier's records. He was part of a HAA unit which was disbanded in March 1944 in India. Soldiers who were A1 medically went to the infantry to be trained in jungle warfare before going on to an infantry regiment. He went to 13 Foresters and then 7 South Lancs which were both training Battalions in 52nd Training Brigade in central India. There are a couple of uses of what looks to me like 'CJBA' in the entries (but I could have got that wrong!). Can anyone help with what it stands for or means? Many thanks
