Mars City (revisited)
Specialist Wilson is a marine in Doom 3 voiced by John Carmack, heard over the radio during the Mars City Revisited level. He and his team were most likely on patrol when the invasion occurred. The whole squad was killed except Wilson. He can be heard reporting in to Sgt. Kelly, asking for orders. The Sergeant tells him to fortify his position and wait for help. 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 were 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.
