Captain Jimmy Manroe was a UNIT officer who served under Brigadier Lethbridge-Stewart. He was assigned to cordoning off Oxley Woods after the second fall of Nestene meteorites, and was the first to come across the TARDIS and the Third Doctor. When the story leaked to the press, he refused to answer the reporters' questions. He later helped the Doctor defeat the Nestene invasion. (DW: Spearhead from Space, MA: Who Killed Kennedy)

Manroe later went back to the regular army. (MA: The Scales of Injustice)
