Adams (The Android Invasion)
From Tardis Wiki, the free Doctor Who reference
Corporal Adams was a UNIT officer stationed at Devesham under Colonel Faraday. The Kraals made an android duplicate of him. (DW: The Android Invasion)
Behind the scenes
In the original script for The Android Invasion, Corporal Adams was a regular army soldier called Private Richard Adams. Max Faulkner had previously appeared as a member of UNIT in The Ambassadors of Death, where he was credited as "UNIT Soldier". It is possible that these two characters are one and the same.
