Fall out fall in (1943)

Private Donald Duck is on a long, long training march, growing steadily more exhausted. Finally, they reach their camp location, and despite Donald's desire for dinner, he follows orders to pitch his tent first. He finally gives up on the tent as night falls. But as he tries to get to sleep, the loud shoring of the other soldiers forces him to bury his head. Finally, he gets to sleep, just as reveille sounds and the march continues.
