Wartime

During World War II, Donald appeared in several animated propaganda films, including the 1943 Der Fuehrer's Face. In this cartoon, Donald plays a worker in an artillery factory in "Nutzi Land" (Nazi Germany). He struggles with long working hours, very small food rations, and having to salute every time he sees a picture of the Führer (Adolf Hitler). These pictures appear in many places, such as on the assembly line in which he is screwing in the detonators of various sizes of shells. In the end, he becomes little more than a small part in a faceless machine with no choice but to obey until he falls, suffering a nervous breakdown. Then Donald wakes up to find that his experience was, in fact, a dream. At the end of the short, Donald looks to the Statue of Liberty and the American flag with renewed appreciation. Der Fuehrer's Face won the 1942 Academy Award for Animated Short Film. Der Fuehrer's Face was also the first of two animated short films to be set during the War to win an Oscar, the other being Tom and Jerry 's short film, The Yankee Doodle Mouse.

Other shorts from this period include a six film mini-series that follows Donald's life in the U.S. Army from his drafting to his experiences in basic training under Sergeant Pete to his first actual mission as a commando having to sabotage a Japanese air base. Titles in the series include:

Thanks in part to these films, Donald graced the nose artwork of virtually every type of World War II Allied combat aircraft, from the L-4 Grasshopper to the B-29 Superfortress.

Donald also appears as a mascot—such as in the United States Army Air Forces ' 309th Fighter Squadron and the U.S. Coast Guard Auxiliary, which showed Donald as a fierce-looking pirate ready to defend the American coast from invaders. Donald also appeared as a mascot emblem for the 415th Fighter Squadron; 438th Fighter Squadron; 479th Bombardment Squadron; and 531st Bombardment Squadron. He also appeared as the mascot for the Fire Department at Marine Corps Air Station El Toro, as well as the Army Air Forces (now currently the United States Air Force) 319 Aircraft Maintenance Unit at Luke Air Force Base — where he is seen wearing an old-style pilot's uniform with a board with a nail in it in one hand, and a lightning bolt in the other hand. Donald's most famous appearance, however, was on the North American Aviation B-25B Mitchell medium bomber (S/N 40-2261) piloted by Lt. Ted W. Lawson of the 95th Bombardment Squadron, USAAF. The aircraft, named the "Ruptured Duck" and carrying a picture of Donald's face above a pair of crossed crutches, was one of sixteen B-25Bs which took off from the aircraft carrier USS Hornet to bomb Tokyo on April 18, 1942, during the Doolittle Raid. The mission was led by Lieutenant Colonel (later General) Jimmy Doolittle. Like most of the aircraft that participated in the mission, the Ruptured Duck was unable to reach its assigned landing field in China following the raid and ended up ditching off the coast near Shangchow, China. The Ruptured Duck's pilot survived, with the loss of a leg, and later wrote about the Doolittle Raid in the book, later to be the 1944 movie, Thirty Seconds Over Tokyo.

During World War II, Disney cartoons were not allowed to be imported into Occupied Europe owing to their propagandistic content. Since this lost Disney revenue, he decided to create a new audience for his films in South America. He decided to make a trip through various Latin American countries with his assistants, and use their experiences and impressions to create two feature-length animation films. The first was Saludos Amigos (1942), which consisted of four short segments, two of them with Donald Duck. In the first, he meets his parrot pal José Carioca. The second film was The Three Caballeros (1944), in which he meets his rooster friend Panchito.

Several decades after the war, because Donald was never officially separated from service in either his animated shorts or his comic strips, as part of Donald's 50th Birthday celebrations during the 25th Annual Torrance, California Armed Forces Day Parade, the U.S. Army retired Donald Duck from active duty as a "Buck Sergeant" (i.e. "Buck Sergeant Duck").
