for sinister purposes. He later tracks down Kang, an assassin working for the People's Liberation Army who had tried to assassinate a former Navy admiral who now works for a communications company. Outside the novels, John Clark's career continues further in the Rainbow Six video game series. In Rainbow Six: Critical Hour, Clark retires and passes the leadership of Team Rainbow on to Chavez. Although Chavez appears in Rainbow Six: Vegas as Rainbow commander, no mention is made of Clark. Awards John Clark has been awarded the Navy Cross, Silver Star with an oak leaf cluster, Bronze Star with Valor devices with three oak leaf clusters, three Purple Hearts and four Intelligence Stars. He is also a recipient of the Medal of Honor, awarded and presented to him by Jack Ryan (then President of the U.S.) for the rescue of a downed fighter pilot during his time in Vietnam (see Without Remorse). He is a simulated major general in the Rainbow Six book, though he only reached the rank of Chief Boatswain's Mate (Chief Petty Officer) during his Naval career. Distinguishing marks Clark has a small tattoo of a red seal, sitting up on its hind flippers "grinning impudently" on his forearm. Though no other visual details are given, a comment made by Lieutenant Colonel Daniel "Bear" Malloy in Rainbow Six indicated that at least some soldiers in Ryanverse who dealt with special operations had heard of the red seal tattoo and understood that it was associated with the Third Special Operations Group (SOG), with whom Clark served during the Vietnam War. Clark stated that everyone in his unit got the tattoo. In the real world, having such a tattoo would violate operations security (OPSEC); however, similar tattoos are not particularly uncommon, so long as the tattoo is not specifically unit identifiable. Also, the Third SOG is not a real military unit, but a similarly named group, the Studies and Observation Group MACV-SOG, was initially named the Special Operations Group and was active in Vietnam in the types of operations and environments referenced in the series, and had Navy SEALs among its personnel. The symbol of the red seal is actually the unit insignia for SEAL Team 1.
