The Leonidas Squadron, formally known as "5th Staffel of Kampfgeschwader 200", was a unit which was originally formed to fly the Fieseler Fi 103R Reichenberg, a manned version of the V-1 flying bomb, in attacks in which the pilot was likely to be killed, or at best to parachute down at the attack site. The Reichenberg was never used in combat because Werner Baumbach, the commander of KG 200, and his superiors considered it an unnecessary waste of life and resources. The Mistel composite aircraft was preferred.

Kampfgeschwader 200 was a German Luftwaffe special operations unit during World War II. The unit carried out especially difficult bombing and transport operations and long-distance reconnaissance flights, tested new aircraft designs and operated captured aircraft.
