Private Snafu - "The Infantry Blues"

Private Snafu is the title character of a series of black-and-white American instructional adult animated shorts, ironic and humorous in tone, that were produced between 1943 and 1945 during World War II. The films were designed to instruct service personnel about security, proper sanitation habits, booby traps and other military subjects, and to improve troop morale. Primarily, they demonstrate the negative consequences of doing things wrong.

The character was created by director Frank Capra, chairman of the U.S. Army Air Force First Motion Picture Unit, and most shorts were written by Theodor "Dr. Seuss" Geisel, Philip D. Eastman, and Munro Leaf.
