It is worse than the ARVIN.
I caught an interview on "morning edition" (NPR) with a reporter who had toured the battle zones.
He said that the troops that deserted claim that the officers deserted first, some of them after a few years of graft , such as not reporting desertions , but pocketing the paycheck of the deserted instead.
Poor leadership and poor motivation has produced a hollow force , it needed a lot more time and a lot better reason to exist.
Now that everyone on the scene can see how desperately bad the ISIS rule is , there may be a lot better motivation, but time is lacking.
