Two improvised satchel charges along with Sidolówka grenades, as used in the Warsaw Uprising

A satchel charge is a demolition device, primarily intended for combat, whose primary components are a charge of dynamite or a more potent explosive such as C-4 plastic explosive, a carrying device functionally similar to a satchel or messenger bag, and a triggering mechanism; the term covers both improvised and formally designed devices.

In World War II, combat engineers used satchel charges to demolish heavy stationary targets such as rails, obstacles, blockhouses, bunkers, caves, and bridges. The WWII-era United States Army M37 Demolition Kit contained 8 blocks of high explosive, with 2 priming assemblies, in a canvas bag with a shoulder strap. Part or all of this charge could be placed against a structure or slung into an opening. It was usually detonated with a pull igniter. When used as an anti-tank weapon, charges were sufficient to severely damage the tracks. 4 kg (8.8 lb) charges were enough to destroy medium tanks.

The later U.S. M183 Demolition Charge Assembly contained 20 lb (9.1 kg) of C-4 in each satchel, and could be used with a timed fuse. In the Second Battle of Fallujah in Iraq, U.S. M2 20 lb assault demolitions were used to collapse houses being used as fighting positions by insurgents, instead of infantrymen clearing the houses room by room.

Special forces may use customized satchel charges designed to destroy their specific mission's target.
