I'm looking to keep my hand/get a few quid by joining the TA. I have my eye on a local infantry unit but have a few questions: I'm ex AGC, 5 years experience, class 1 and would like to do an all arms infantry course. Saying that, I can see how my AGC experience might be more useful to the unit. Particulary as the unit may be deploying to Afghan. I assume a deployable experienced clerk might be more useful than a newly trained infantry soldier if the unit are short on clerks. How strict are the roles in the TA? Could I, in essence be 'dual trained' if I get in, or would I have to pick one or the other?
