Photo G2139: Members of 3rd Platoon, 4th Squad, B Company, 720th MP Battalion escort on the Tay Nih-Cu Chi Convoy in Tay Ninh Province, III Corps Tactical Zone, Vietnam took their Parrot named "LT Polly" on the escort in February 1967. The joke was if a canary in a coal mine gave early warning of danger, then a parrot on a perch in a jeep could warn of an enemy ambush. Courtesy of SP/4 Alan M. Portnoy, B Company & 615th MP Company, 720th MP Battalion, 89th MP Group, 18th MP Brigade, October 1966 to October 1967.
