Directorate of Miscellaneous Weapons Development

The Directorate 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, which was corrupted to Instigator of Anti-Aircraft Wheezes and Dodges.
