A C-4 charge packed onto a marine anchor chain. Plastic explosives are especially suited for explosive demolition of obstacles and fortifications by combat engineers as they can be easily formed into ideal shapes for cutting structural members and have a high enough velocity of detonation and density for metal cutting work.
The "Grenade, Hand, Anti-Tank No. 74", commonly known as the S.T. grenade [a] or simply sticky bomb, was a British hand grenade designed and produced during the Second World War. The grenade was one of a number of ad hoc anti-tank weapons developed for use by the British Army and Home Guard after the loss of many anti-tank guns in France after ...
RDX is often used in mixtures with other explosives and plasticizers or phlegmatizers (desensitizers); it is the explosive agent in C-4 plastic explosive and a key ingredient in Semtex. It is stable in storage and is considered one of the most energetic and brisant of the military high explosives, [2] with a relative effectiveness factor of 1.60.
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.
Stielhandgranate is the German term for "stick hand grenade" and generally refers to a prominent series of World War I and World War II–era German stick grenade designs, distinguished by their long wooden handles, pull cord arming and cylindrical warheads.
The Composition C family is a family of related US-specified plastic explosives consisting primarily of RDX.All can be moulded by hand for use in demolition work and packed by hand into shaped-charge devices.
The first blasting cap or detonator was demonstrated in 1745 when British physician and apothecary William Watson showed that the electric spark of a friction machine could ignite black powder, by way of igniting a flammable substance mixed in with the black powder.
