This vehicle is based on a US Army 5 Ton truck.  Let's face it, the new LMTVs don't look as good as the older 5 tons.  Anyways, this truck has basicly no Armor.  It has a gunners hatch on the cab just in case someone decides to mount a weapon.  Usually there wont be a weapon mounted on a supply truck though.  That's what gun trucks are for.
