Mk 153 Shoulder-Launched Multipurpose Assault Weapon

The Mk 153 Shoulder-Launched Multipurpose Assault Weapon (SMAW) is a shoulder-launched rocket weapon with the primary function of being a portable assault weapon (e.g. bunker buster) and a secondary anti-armor rocket launcher. Developed from the B-300, it was introduced to the United States Armed Forces in 1984.It has a maximum range of 500 metres (550 yd) against a tank-sized target.

It can be used to destroy bunkers and other fortifications during assault operations; it can also destroy other designated targets using the dual mode rocket and main battle tanks using the High-Explosive Anti-Armor (HEAA) rocket. Operations in Afghanistan and Iraq saw a thermobaric rocket added (described as a "Novel Explosive" [NE]), which is capable of collapsing a building.
