Composition 4 (C4), is a plastic explosive composed of RDX, plastic binder, plasticizer, and a marker chemical to identify its source. It is 1.34 times as explosive as TNT and has been used since the 1960s when it was developed. C4 is often used in breaching obstacles or demolition of large structures.
