U wouldof got urself trapped in a wrong war for nothing - wrong cause, wrong place, wrong time, and wrong enemy that will be different from the "real enemy" in every single way. The so-called "war exerience" u gain from such exercise will worth nothing when facing a completely different enemy (and it will be the case u betya!) but giving u a false sense of confidence.
Look, exercise just for exercise's sake won't work.
