Old-school Cavalry sergeant Hap Doan (Wallace Beery) was disgusted with the armored vehicles that were replacing the regiment's horses, and the last straw came when a runaway tank injured his own beloved mount. Going AWOL in protest, the disgruntled corpsman finds himself dishonorably discharged...and perhaps the perfect patsy for some ambitious saboteurs. Service story co-stars Marjorie Main, Lewis Stone, Donna Reed, George Bancroft. 102 min. Standard; Soundtrack: English Dolby Digital mono.
