Security guard (Bad Wolf)

The security guard was a military guard for Satellite Five. When the 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. (DW: Bad Wolf) He along with the other guards, would've stayed to defend the satellite from the Daleks, and was killed.
