Medium Atomic Demolition Munition (MADM) was a tactical nuclear weapon developed by the United States during the Cold War. It was an atomic demolition munition (ADM), a combat engineering device for demolition of structures and for battlefield shaping. The device contained a W45 warhead with an estimated yield of 0.5 to 15 kilotonnes of TNT (2.1 to 62.8 TJ). Each MADM weighed 391 pounds (177 kg) in its transportation container. They were deployed between 1962 and 1986.

In service, the MADM was known as the M167, M172 and M175 Atomic Demolition Charges (ADCs).[1]
