Information on the raider concepts:
The Punk http://fav.me/d5ga8tw : Raider Punks are who you would say have listened to maybe a little too much Motley Crue and 80's hair metal for their own good. Clothing wise, Punks typically don tight leather pants with some form of mohawk, shirts are optional. Weapon preferences vary from Punk to Punk, but many Punks prefer shotguns and powerful handguns.
The Road Warrior http://fav.me/d54taa1 : Pretty much the baddies in the Mad Max movies.
The Bruiser http://fav.me/d5ga9da : If you like smashing things, wearing heavy armor, or dismembering organisms, you're probably a bruiser, especially if you love using melee weapons all the time.
The Anarchist http://fav.me/d5ga9l9 : Anarchists are natural-born leaders and have an affinity for molotov coctails and makeshift weapons.
The Bomber http://fav.me/d5etbk5: If you're a Bomber, then you love explosions. If raiders had Youtube, you'd be the guy who stays up all night watching videos of atom-bomb tests.
I personally view myself as a mixture of a Road Warrior and a Punk.
