Depends on you corps/regiment & trade.
A lot of driving training such as LGV C & C+E and Hazmat are being curtailed due to budget cuts etc.
If you RLC or REME you may, just may stand a better chance as you may need them in your trade.
But getting loaded on to a course can take time as others have stated.
Oh and what you get told now may well be different by the time your ready to do the training!!!
