They missed two really important points:

The OCS guys stay past eight years in greater numbers because they like what they're doing. The USMA and ROTC grads leave in greater numbers because they do not like what they're doing -- and I submit that a lot of Staff jobs aid them in making that determination. The OCS person will endure the staff because the Army is more important to him than the petty foolishness -- or his wife. OTOH, the bright young thing will not stay because his wife is more important than the Army and the 18-20 year old who is calculating enough to opt for a scholarship probably had other things in mind down the pike in any event...

The solution, therefor, is to reduce the number of ROTC scholarships AND Staff positions. As the US Army is significantly over-officered with respect to the Officer to EM ratio, that should not be a problem. As they note, the Officer Corps is currently authorized at about 20% of enlisted strength -- about twice what it should be.

I realize that over strength is to cope with situations such as the current shortfalls -- but the situation is not that bad. Over strength is also designed as a mobilization hedge. That is certainly needed but there are other ways to do that...

Those are minor quibbles; they say:
the Army should develop the institutional adaptability to place the right officers in the right jobs at the right time.
Couldn't agree more though HRC will object, I'm sure -- which means the authors are on the right track.

They ought to also look at doing away with the Warrant Officer program. I know a lot of WOs like it (what's not to like ) but I think the Army would be better served by making those guys commissioned officers. If they have enough talent to be WOs, they probably have enough to be commissioned -- particularly if we realize that 'up or out' is a lousy way to do business. There's a lot of talent in the Army and the Army does a poor job of tapping it -- I will note that a lot of that talent does not want to be commissioned for various reasons; responsibility, conformity, socialization and a lot of hard days probably being the top four things they wish to avoid. A couple of those are fixable and we wouldn't want those who'd be excessively concerned about the first and last in any event.

Oh -- and tell the Air Force to go pound sand and make the average Helicopter Pilot a NCO instead of a Warrant.
