It might seem like a dumb question, but I'm new to military research. I'm trying to collate information on my father's war service. I have not much to go on. The best hope is a hand-written note, stamped by a censor, sent to my mother in 1943 which begins with "1534020 L/SGT J FREEMAN 17 INDIAN HY AA BTY INDIAN COMMAND 5". I can confirm that "1534020" is his army number (it appears on my birth certificate, along with "Royal Indian Artillery"). I guess his rank was Sergeant, which is consistent with a photograph I have of him in uniform with three chevrons on the sleeve, but what does the "L" signify? What does the remainder tell us? A "Soldier's Release Book" dated 1946 shows "Present Rank" as "W/BDR". Is this "Bombardier"? Is this a lower rank than Sergeant? Unfortunately the entry for "Unit, Regt, or Corps" is too faint to be legible. I understand that I can get more detail from MOD, but I'd like some info to work on in the meantime. Thanks in anticipation of some enlightenment.
