when he marries his daughter Patricia, and they later have a son, John Conor, who was born in Rainbow Six, although misnamed as John Patrick in Threat Vector. Professional life When Clark was 18, he joined the US Navy (as John Terence Kelly) and later became a Navy SEAL who participated in several special operations, one of which was the rescue of a naval aviator shot down over North Vietnam. The aviator was the son of Admiral Dutch Maxwell and his rescue earned Kelly a promotion to Chief Petty Officer. After his first tour of duty, Kelly left the Navy but was later re-hired by the Central Intelligence Agency's (CIA) Special Activities Division (Special Operations Group) for another mission in Vietnam; a rescue operation on a secret POW camp. At the same time, Kelly was carrying out his own war at home against a drug ring that killed his girlfriend, Pamela Madden.
