I would definitely do it again, for even less money, more crap kit, more sh it postings and no promotion. Sorry, where am I, is it time for my medication...........what are those things you are attaching to my temples??.......what do you mean electricity..........Ohhhh!!
Yes, without a doubt. If you've hated it so much then you either haven't got off your arrse and made the most of it, haven't got the personality to make a lifetime's worth of friends or you should have left earlier.
Yes, there's loads of problems, particularly regarding disruption, but when that gets too much, leave.
There are no excuses for not gaining from the Army - you get more training than most civis get in a lifetime, you can turn round and apply for any number of career changes without putting your job at risk (aircrew, SF, dogs etc), there's free education to be had within reach of almost all postings blah blah blah.
Adv trg and sport are fading in to things of the past for many units, but the opportunities are still there if you badger people enough or are willing to get organising.
If any of this applies to you then I suggest you phone up your education centre, courses clerk, gym, boss and start doing something about it.
Probably come in as a Lawyer though. A couple of years away from the cut and thrust of Civ Div would be nice.
Either that or I'd join as a Woman. Live up to the lowest expectations possible, loaf about with a sick chit, carry half the weight of any bloke (or get them to carry it for me), get paid whilst up the duff, nail my SNCOs AND get my tits done for free!
