Corporal B. Scott was a MACO assigned to the ISS Enterprise in 2155. Scott was one of several Enterprise crew members that left the starship in escape pods when the craft was trapped by Tholian vessels in an energy field and destroyed. The life pods and their occupants, including Scott, were later retrieved by the USS Defiant, under orders from Commander Jonathan Archer, an officer who had led an assault team there from Enterprise.
Later, Scott helped Captain Archer to search the Defiant for Slar, a member of the reptilian Gorn species. Scott was killed by the creature when he tried to defend the captain from an attack in a corridor of the Constitution-class ship's primary hull. (ENT: "In a Mirror, Darkly")
