Satchel Charges. There are two standard satchel charges: the M183 and the M37. Both
come in their own carrying satchel with detonators and blasting cords. Each weighs 20
pounds. The M183 has 16 individual 1 1/4-pound blocks that can be used separately. When
used untamped, a satchel breaches a 3-foot-thick concrete wall. Satchel charges are very
powerful. Debris is thrown great distances. Friendly forces must move away and take cover
before detonation.
d. Cratering Charges. The standard cratering charge is a 43-pound cylinder of ammonium
nitrate. This explosive does not have the shattering effect of bulk TNT or C4. It is more useful
in deliberate demolitions than in hasty ones.
