Lieutenant Colonel Alvin H. Davenport, callsign "Chopper", was an Osean pilot, lieutenant colonel, and the third member of the Osean Air Defense Force's Wardog Squadron. Davenport's pet dog, Kirk, was the inspiration for his squadron's name and emblem. Davenport was a well known chatterbox among the personnel stationed at Sand Island Air Force Base, and his penchant for cheeky remarks often earned him the ire of his superiors, such as AWACS Thunderhead. He calls the Protag (Blaze) "Kid".
