Atomic demolition munitions (ADMs), colloquially known as nuclear land mines, are small nuclear explosive devices. ADMs were developed for both military and civilian purposes. As weapons, they were designed to be exploded in the forward battle area, in order to block or channel enemy forces. Non-militarily, they were designed for demolition, mining or earthmoving. Apart from testing, however, they have never been used for either purpose.
