It all depends on what they are going to be doing in the military and how much follow-up training they receive when integrated into the army.
As post 15 pointed out we were taking trainees with 8 weeks of basic and then integrating them into our combat-ready division by giving them OJT (on the job training).
14 years as a US AF PJ and this still baffles me as to their overall effectiveness once they hit the actual battlefield.
Even so, I suppose one has to do what one has to do. But I don’t see this ending well for many of them, at all.
