Great Guns! is Oswald the Lucky Rabbit cartoon produced by the Walt Disney Studio and Winkler Productions. It was re-issued by Walter Lantz Productions in 1932. It was originally released on October 17, 1927.^[1] Great Guns! is a parody of war films, a popular film genre during the silent era.

War is declared and Oswald enlists in the army. He shows off his uniform and weapon to impress his girlfriend. Later he is shown in a trench in a battlefield kissing her photo. A mouse piloting an airplane drops a bomb, destroying the photo. Angered, Oswald boards a plane and engages in a dogfight with the mouse's plane. Both planes crash and they begin hand-to-hand fighting. A large enemy dog approaches, causing Oswald to attempt to flee. He encounters an elephant and uses the elephant's trunk to fire cannonballs at the dog. The dog fires cannonballs back at Oswald from a cannon. Oswald catches most of the balls and throws them back, but one hits Oswald, reducing him to coal. His girlfriend, now a Red Cross nurse, appears and gathers the pieces in a basket and takes them to a hospital. She pours them into a cocktail shaker and after shaking them, pours them out and restores Oswald. They joyously embrace and kiss each other.

The short was released on December 11, 2007, on Walt Disney Treasures: The Adventures of Oswald the Lucky Rabbit.^[2]
