I see guys in bars around here try that, they come in a dressed in their military shit, and try to use it to their advantage, they also seem to find themselves involved in a lot of fights too, whether it be some other drunk douche starting shit with them, or them starting shit with the other random drunks, though I've always felt is was rather pathetic if a guy had to brag about something (job, car, house, money, etc.) in order to get the girl, if you can't get just being yourselves then it's either not meant to be, move on
There's idiots out there that think they're bad-ass if they can beat a military man. I've never seen it happen...
