Medium Atomic Demolition Munition

Medium Atomic Demolition Munition (MADM) was a tactical nuclear weapon developed by the United States during the Cold War. They were designed to be used as nuclear land mines and for other tactical purposes, with a relatively low explosive yield from a W45 warhead, between 1 and 15 kilotons. Each MADM weighed less than 400 lb (181 kg) total. They were deployed between 1965 and 1986.
