Seriously though, have you not joined yet Fordy? You were posting for advice on units nearly a year ago.
In my little experience of TA clerks it seems quite a good job. They get to do the good stuff with the rest of us, and when there is crap to do they can go and do their proper job. Always been good lads and lasses too and more than helpful.
I don't know if thats just the units I've worked with, or a wider experience?
