Here's a link to a story from the Associated Press that I just read about Army National Guard recruiting. This confirms something I learned on a trip down to Camp Curtis Guild (Reading, MA) a few months ago and have written about here -- contrary to the myths about desparation among military recruiters, the Guard these days is ratcheting standards up and turning would-be recruits away in droves.
The prevailing theory mentioned in the article is that the Pentagon is trying to simultaneously grow the active-duty force and shrink the Guard in order to rely on the active troops more in wartime. Active troops, of course, are far less *visible* to non-military Americans because they're more likely to be residentially clustered on or near military bases, and they don't hold full-time positions that go unfilled during call-ups. Therefore, it's less abrasive politically to mobilize active-duty troops for repeated tours of duty than it is to use Guardsmen, who hold a special sort of status within the military in that they're Governor-owned and also ready for tasking in case of domestic emergency.
Still, that doesn't change the reality for anyone in the Guard who's either overseas now, has just gotten back, or is just about to go. I'd say that about sums it up for every Guardsman or Reservist that I know (assuming we can say "just gotten back" extends a couple years).
If you're interested in this sort of stuff, it's worth a read. And if you didn't already know that the vast majority of American high school graduates are ineligible for military service, either due to poor physical fitness, background disqualifications, medical conditions, or subpar ASVAB scores, well, now you do.
