Remember patriot, when our guys are off righting the wrongs inflicted against us, we'll be here to take care of any domestic troublemakers. That, and someone has to see to it that all those girlfriends and wives of servicemen aren't taken undue advantage of by unAmerican civies... :-)
Also, what's with this "one shot, one kill" business?? One shot from your grenade launcher should kill more than one evildoer, and there's nothing better than a bad guy to practice your 250 yard groupings on (maybe it just all averages out)...
Even better: one regimental time-on-target, one brigade shredded (for the cannon-cockers) and one air group Rockeye pass, one Highway of Death (for the Air Wing). OOH-RAH!
