Doc

Doc (also known as G.I. Joe Doc) is the code name of two fictional characters from the G.I. Joe: A Real American Hero toyline, comic book and animated series by Sunbow/Marvel.

The first is Carl W. Greer, who is the G.I. Joe Team's original medic and debuted in 1983. The second fictional character to use the code name was Carla P. Greer, the niece of the original Doc who has the same rank and skills.

His real name was Carl W. Greer and he was ranked as an O-3 Captain. He was born in Concord, Massachusetts. His primary military specialty was medical doctor and his secondary military specialty was chaplain's assistant.

Doc was the first member of the G.I. Joe medical team, and possibly the only one with a terminal degree; his M.D. Doc is a graduate of Harvard Medical School, and completed his residency at Johns Hopkins to become a full medical doctor. He also completed training at the Airborne School, Mountaineering School and the Desert Training Unit. He is an avowed pacifist for practical reasons, in accordance with the Geneva Convention guidelines for battlefield medics. A spiritual man, he devoted himself to alleviating suffering in the world, and admired the G.I. Joe Team's efforts to do the same, by challenging those who would bring about violence and chaos.
