UNMC is a bad idea in my opinion. It was good back when it was created but ultimately ended up being shit. It brings nothing RP wise other than giving certain people bragging rights over equipment only they can access. It's effectively ruined other servers with their own implementations (ie. Nato) and I really don't see the point. Should concentrate on the police, rebels and hobos to improve on everyone's role-playing experience.
There's a place for groups like UNMC in mil-sims. Not altislife.
