The M141 bunker defeat munition (BDM) is a disposable single-shot, shoulder-fired rocket launcher designed to defeat hardened structures. It is a modification of the United States Marine Corps Mk 153 shoulder-launched multipurpose assault weapon (SMAW) and is also called the SMAW-D (where D is for disposable). It was designed to fill the void in the United States Army inventory of a "bunker buster" weapon.
