TSG I'm ok with. Random "militias" created in some dude's basement... not so much. I've always been wary about organizations that are unsanctioned, simply because these are the groups that the government is most likely to label as dangerous. Say one of these private armies does something that the government deems hazardous to national welfare or somewhat terroristic. If things were to get out of hand, I really don't want to be at war with the U.S. with my name on a blacklist and FBI trying to hunt me down.
