Final credited acting role of Alejandro Rey.
In order of descending rank Hannibal is a Colonel, Murdock a Captain, Face a Lieutenant and BA a Sergeant. Although Murdock technically outranks him when Hannibal is absent it's normally Face who takes charge due to Murdock's apparent insanity. Hannibal, Face and BA were all Green Berets, members of the US Army Special Forces. In A Nice Place to Visit (1983) we see Murdock wearing his formal uniform at a funeral and see that he was an army helicopter pilot but not a Green Beret. His uniform does display the Parachutist Badge (Airborne wings) showing that he has undergone paratrooper training. Frankie claims to have served as a paratrooper although the rest of the team regard this with suspicion given his inability to use the military 24hr clock system.
At the beginning, the map shown as a San Marcos' is really the Rapa Nui's ("Isla de Pascua" [Spanish], "Easter Island), belonging to Chile's territory.
