After years of agitating for this sort of thing, U.S. Army troops have finally convinced the brass to create a realistic wargame where each game character (or "avatar") would not just represent the soldier playing the game, but would portray that players' actual physical characteristics (speed, strength, accuracy with weapons and so on) and appearance (shape and face).
This is genius. Take advantage of the fact that young men will play first-person shooter games for all hours by providing access to realistic games that reflect your personal characteristics. And allow the troops to update their avatar's characteristics based on their PT scores and education credits.
You train the way you fight because you'll fight the way you train. We can add that our troops should play the way they are able to fight because they'll fight as good as they played.
