Satchel charge

In World War II, combat engineers used satchel charges to demolish heavy stationary targets such as rails, obstacles, blockhouses, bunkers, caves, and bridges.

The World War II–era United States Army M37 Demolition Kit contained eight blocks of high explosive, with two priming assemblies, in a canvas bag with a shoulder strap.

Later in the Vietnam War, Vietcong and North Vietnamese soldiers assigned elite sappers to stealthily penetrate defenses of sites controlled by enemy forces.

Often, this meant using satchel charges as well as Bangalore torpedoes to blast through barbed wire entanglements, minefields, structures, and other fortifications.

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.
