I think there may have been a thread on this before, not sure.
I think the TA section of the Army website alludes to it as well. If I remember rightly, it cleverly underplays the "real world" commitment required of young subbies after Sandhusrst i.e. PCD, annual camp, range quals, Cambrian etc, etc.
Various types of 'get your commission in one quick and easy go' schemes have been tried before and all failed.
Why? Because (in my experience) most of the people who go through them find that the weekly grind of being a platoon commander - of getting to training nights after work, chasing non-attenders, planning lessons etc etc - is not as much fun as the offficer training where they (pretty much) only had responsibility for themselves.
Result? The Army pays to train people who leave or become dead wood a few months after being commisioned.
Awaiting a flood of examples to show I'm wrong ...
DS, check out this previous thread - after some inital ramblings re the dearth of junior officers in the TA, a discussion about the Army's Cunning Plan to remedy the problem using the Rear Entry scheme kicks off:
I am enlightened. toying with the idea of rupertdom. Wanted to see how much more I'd have to do. Of course I realise I'd have to have the frontal lobotomy to remove any navigational prowess, common sense or discipline
I was a little surprised to find out that Rear Entry was an option available to people already in the TA. I thought it was designed to hoover up unsuspecting punters and turn them into ruperts. But lo, verily, it is there for one and all.
If you're already in, you'll need approval from the head shed in your unit to go forward for a commission, though. If that is not forthcoming, threaten that you'll resign and then ping back in via Rear Entry at some other unit (you'd probably be snapped up) - they will probably see sense and let you go for it.
