RA Training Branch?

Is there such a thing in existence,
where people as young as 16, are trained up on an LSW,
in a matter of 3 days AND uniformed?

This is allegedly connected to the TA. The Royal Artillery Training Branch.

I feel like an idiot even posting this now...

But I know somebody who thinks he is something special and wish to put him right.
never heard of it, sounds like you mate is having you on
