Honestly if you expect the Army to give a more accurate picture of what the Army really is, it isn't ever going to happen. Who would want to play a game where you wake up muster for duty, spend a few hours standing watch with nothing going on, do drills, march, and stand around whining about being bored. Then you get the joy of driving a humvee with a couple of officers in it across the base. Then you get to wash said humvee. Clean dust filters, clean weapons, clean the barracks, clean more stuff, and pretty well do nothing for months.
It is a smart idea to get people interested in the Army. It should not however be the sole deciding factor in whether a person joins. Anyone that decides to do something based solely on a video game is a fool. However it may get someone interested in talking to a recruiter.
On a somewhat related note, everyone I have ever met that served came out a better person. Not saying that nobody comes out worse, it is just that I haven't seen anyone who came out a worse person than when they went in.
