Penguin General has a black vest and helmet skin. The base colour is easy as hell, but more than that, while it can be done, isn't nearly as easy. Theres two texture files, one for the base camo, and one for the rest.

Just a thought, if you replace the desert MARPAT in that with my 3 colour (see earlier in thread), you would have somthing fairly close to delta, as seen in the movie Black Hawk Down.
