Stokey,
My dad joined up at 16 but didn't pass out until he was 18 due to glandular (sic) fever. He was pinged early on as being a signaler becuase he had 2 O-Levels. As he put it, "more than the rest of the troop put together!" So like Artists has said, you would probably find yourself on a training course or the like. You know you said 18 year old couldn't go into combat, when was that passed as a law? Was it in the 80's because I'm sure I read somwhere that a 17 year old lad had his foot blown off in the Falklands.
Heres one for you Artist:
When he passed out he thought he was off to 41 Commando (now defunct) and the sunny sights of Malta. What a fantastic first posting he thought! Then on the parade ground when they were receiving their postings, he was asked
"Where do you think you're off to Emmerson?
"Malta Sgt"
"Wrong. Double over to the Signal and Clerks Training Wing"
Needless to say, I don't think he was massively impressed!
