Mail Call is a militainment television program appearing on History Channel and hosted by R. Lee Ermey, a retired United States Marine Corps Staff Sergeant, (given the honorary rank of Gunnery Sergeant in May 2002). The show debuted on August 4, 2002 and is presently part of the 'Fighting Fridays' lineup that airs on Friday evenings. Most episodes are 30 minutes, but as of 2007 some more recent episodes have been 60 minutes.

Comic relief is provided as Ermey inflicts DI-style verbal abuse on his viewers or tests the effects of various weapons on watermelons (the host's "sworn enemy") and paint cans, as well as occasional appearances of "Mini-Lee", an action figure styled in Ermey's likeness, often seen berating a luckless GI Joe figurine. His demeanor as host is similar to the character "Gunnery Sergeant Hartman" portrayed by Ermey in the Stanley Kubrick film Full Metal Jacket, though this attitude is shown only towards his viewers (e.g., insisting that his viewers return after a commercial break) and not the military special guests.
