having served for 6 years as a trainer in US Army Intelligence, i have to agree with Tawakalna about the US enlisted. to be fair, there are plenty of lieutenants ("butter bars") fresh from OCS, that are so dangerously stupid that they should be put under a sergeant's charge until they grow a clue, but that is another discussion.
as a group, the "lifers" (those who stay in the service until they retire) are noticeably less intelligent and motivated (there are some exceptions, but they are few). they stay because many of them are allowed to be marginally useful. these marginal types would have trouble adapting to the private sector (which already has more than enough drones). the military is a machine, and as long as you are a suitably shaped cog, you will be allowed to remain.
i don't care what the statistics say. about 140 of the 160+ people in my basic training company would have been more useful as fertilizer. if i offended someone who shares that low level of functionality, then good, they deserve it (perhaps the AC is one?).
if the human race doesn't start breeding for ability soon (instead of just for looks, or because it's fun and easy), we may render ourselves extinct.
