Where can I watch Operation Dumbo Drop in United States?

Five Green Berets stationed in Vietnam in 1968 grudgingly undertake the mission of a lifetime -- to secretly transport an 8,000-pound elephant through 200 miles of rough jungle terrain. High jinks prevail when Capt. Sam Cahill promises the Montagnard villagers of Dak Nhe that he'll replace their prized elephant in time for an important ritual. But for Capt. T.C. Doyle, the mission becomes a jumbo-sized headache!
