I'm looking into joining the TA, and have a place at University starting in September. I know that being in the TA whilst at University isn't a problem, but I'm a bit keen and want to get stuck into the TA as soon as possible. By sheer coincidence my local TA regiment and the one that will be local to my University are both infantry. What I want to know is would it be possible to join my local TA unit now and transfer come September? One more question; I'm hoping to apply as a regular officer once I complete my degree, and so am going to apply to be a TA officer to get a feel for it. However, I don't actually plan on being an infantry officer in the regular army, how hard is it to transfer to being a regular officer and change regiment?
