Tom Burton

Major Tom Burton was the chief security officer at Chadwick Green's Research centre who helped the Tenth Doctor fight a group of Cybermen who were built on Earth during the Battle of Canary Wharf. He had his soldiers create a special rocket launcher that was used to destroy some of the Cybermen when they attacked Chadwick Green, but when most of the rocket launchers were destroyed, he tried to use the last one to kill the Cyberman, but he was killed when one of the Cybermen blew up the rocket launcher by shooting it.
