Security guard (Bad Wolf)

The security guard was a military guard for Satellite Five. When the Ninth Doctor, Jack Harkness and Lynda Moss were arrested, he tried to interrogate them, sentencing them to a life term at the Lunar Penal Colony. The Doctor and Jack knocked him and the other guards out and reclaimed their weapons, ready for Floor 500. He along with the other guards, would've stayed to defend the satellite from the Daleks, and was killed. (DW: Bad Wolf)
