In war you might have fighter and ground based air defenses to deal with. In training you definitely will.

Not saying RJ drivers can't do it, some can, but they really need to attend the whole training pipeline. If there was a big war on and we had more planes than pilots, sure it would be just like WW-II, put on a new uniform and off you go. But that's not where we're at.
