Not the point at all. If you consider MoH and Half-Life to be in the same genre, I can see where the problem is, because other than FPS they are not. Sci-fi games can make up their own vocabulary and reuse military jargon as they see fit. Why should I buy a game who's terminology indicates that the multiplayer component is only a training exercise generally played out with MILES gear or paintballs? I may as well get Police Trainer.
A game designed, advertised, and sold as either an historical or modern reality based combat FPS really shouldn't try to redefine a term already in use by the military depicted. Or did the "F" in FNG for Call of Duty 4's first mission change to "Frakking" between when I first enlisted (and was the fucking new guy) and now?
