Dan,
They may well have an "accelerated" program for those with prior experience, but i assure you that you will take all of the training required by the syllabus. Not only does this get you the required training, but it protects you from moving too fast, too far in trg, and maybe getting behind the power curve...and allows the Military to release you if found lacking.
By the book all the way, or the redresses will swamp you.
Bottom line- if you pass selection, you have an excellent chanvce of going Tac Hel.
Cheers- Garry
