Barnes (Queen of the Daleks)

Barnes was a Sergeant in U.N.I.T. In 1978 he was in charge of a U.N.I.T. base in East Grinstead. He met the Fourteenth Doctor and Erin and didn't initially believe the Doctor was who she said she was. When the Dalek mutant reactivated a Dalek casing, Barnes along with a group of soldiers attempted to stop the Dalek from escaping but failed, Barnes was then exterminated. (DW: Queen of the Daleks)
