Large segments of the episode make direct reference to the TV show M*A*S*H*. The M*A*S*H* theme is played over the establishing shot of the field hospital, and the surgeon robot, iHawk speaks in the voice of Alan Alda as Hawkeye Pierce.
Todd Susman, the original voice of P.A. announcer in M*A*S*H, replays that voice in this episode.
Fry trains with a hovering drone in a reference to Luke Skywalker's lightsaber training on the Millennium Falcon in the movie Star Wars Episode IV: A New Hope, only here, the drone is actually a pinata.
The "Alien Weapons" used by the soldiers in this episode are charged up by winding up the crank (like a jack-in-the-box) on the weapon.
