Marcus Williams

William was an Earth Starfleet officer in the 22nd century.

History
By 2151 he held the rank of commander and served at Starfleet Command. He was the attaché to Vice admiral Maxwell Forrest.

He accompanied Admirals Forest and Leonard to Starfleet Medical, where the group, along with Captain Jonathan Archer confronted Ambassador Soval and his staff about Klaang how crash-landed on Earth. Williams was greatly frustrated with the Vulcans effort to take away control from Starfleet in the matter. 

In 2153 he placed a bet with Drake, an archaeologist, about the existence of a crashed spaceship an the Arctic Circle. Shortly after the team found the ship, Starfleet Command lost contact with them. After three days without, Williams and Forest along with a security team, traveled to Arctic. They found no trace of the researchers. 

In 2154, after Enterprise's return from the Xindi mission, Williams was one of the persons how debriefed Captain Archer.
