TM 31-210 Improvised Munition Handbook

The TM 31-210 Improvised Munitions Handbook is a United States Army technical manual intended for the United States Special Forces describing manufacture of improvised weapons and explosives from readily available materials, from junk piles, common household chemicals and supplies purchased from regular stores. It was first published in 1969 by the Department of the Army.

Among the weapons described are the hand grenade in a can trap that was used against U.S. troops in Vietnam, and the water in a bucket timer that is used by Afghan guerrillas to launch rockets against U.S. military bases. Also worth noting is the altimeter switch used to ignite a bomb on an aircraft at approximately 5000 ft.

Chapters cover the manufacture of explosives and propellants, mines, grenades, small arms weapons, ammunition, mortars, rockets, incendiary weapons, fuses, and detonators.
