The Department of Miscellaneous Weapons Development (DMWD), known colloquially as the Wheezers and Dodgers, was a department of the Admiralty responsible for the development of various unconventional weapons during World War II. The nickname was derived from their original title, the Inspectorate of Anti-Aircraft Weapons and Devices, IAAWD, (an office of Admiral Somerville) which was corrupted to "Instigator of Anti-Aircraft Wheezes and Dodges". Charles Goodeve was responsible for its expansion from an Inspectorate and widening of its role.
