Specialist Wilson is a character in Doom 3 ,voiced by John Carmack . He is a Marine in Mars city . He and his Team where on out, most likely on patrol, when the Invasion occurred . The whole squad was killed, excep Wilson. He can be heard reporting in to Sgt.Kelly, and asking for orders. The Sargean tells him to fortify his position and wait for help. But the player does not hear him over the radio again. It's possible that Wilson was killed while trying to fortify or hold his position, given how many other Marines where overwhelmed or ambushed.
Specialist Wilson is not encountered directly, but is most likely a technology or weapons specialist, possibly a demolitionist, heavy weapons operator, or similar.
