Hi Susan, Just a note of clarification: in the RA "gunner" was a rank. (Can't remember if it was equivalent to Private in other branches.) Although it could also mean a member of the RA in the abstract, or "gunners" for all RA members together. Unlike in RAC tank crews, it was not used to refer to the man who actually took the action which fired a gun. Men assigned to a gun or a self-propelled gun like a Sexton were given numbered roles. The "Number One" would be in command of the gun. If there were seven other men in the gun crew they would be numbers 2-8. That's all to the best of my knowledge and I hope I haven't made any mistakes.
