You need to do some research about military posers. I think the only thing wrong is that current punishment is not nearly enough, surely not overkill.
I agree wearing an unearned medal is very wrong, but shouldn't the disgrace of being caught at it be enough?
The reason one would do that is to get unearned appreciation, but if caught, all he gets is embarrassment and disgrace.

I'm retired Army, ODS Vet with a chest full of medals when appropriate. I've seen plenty of "posers" over the years, with or without the medals. ;)
I would say that not enough of these posers are punished. But the punishment need not be inordinately severe, just severe enough that they not do it again.
Most of these guys are pathetic, to be sure, but they need not be locked up with violent criminals.
