Hay Foot is a 1942 American military comedy, a sequel to Tanks a Million which brings back most of the characters from that film. The two leading characters, sergeant Doubleday (played by William Tracy) and his rival Sergeant Ames (Joe Sawyer), would go on to feature in six more films.

This was one of Hal Roach's Streamliners, films less than an hour designed to fill out a double feature bill. Fred Guiol directed seven of the eight Doubleday/Ames films, the exception being 1951's As You Were.
