I will cut some slack here.  I had Ooh-rah coming out my ears in high school.  Just temper it all with a little realism.  It isn't all gun kills on MiG-25s.  Being in the military is a little like being a cop.  A lot of paperwork in between hooking up bad guys.  Only a few get to chase the perp accross the crowded city square.  To paraphrase "So I Married an Axe Murderer," not so much Serpico, more Fish from Barney Miller.  The military has some great things, but if you think it will be a living video game, you'll be in for a shock.
