A Liberian man was a UNIT officer from Liberia entrusted with an Osterhagen key. He was one of the three UNIT soldiers who planned to carry out orders to use the project, his point of activation being Osterhagen Station 4.

Unlike Martha and Anna Zhou, he refused to reveal his name due to what they were going to do. He waited for Martha to finish her transmission to the Daleks. However, since Martha was teleported away, they could not activate the Osterhagen Project. (TV: Journey's End)
