Yes, the good old C4 explosive. If you were not in the military, you probably heard of C4(Composition Four) from action movies or video games. C4 is the go-to explosive for the military, combining stability in storage and handling with lightweight and high explosive yield.

Let me take a guess. You know C-4 from one of the best-selling games in history, Counter-Strike. You were probably in the CSGO lounge or looking forward to the CSGO majors in Rio de Janeiro when you just happened to stumble upon the thought, “Does C4 in the game work the same in real life?”

If you’re not a fan of Counter-Strike, you probably know this from the violent console and PC games such as the Grand Theft Auto franchise and the Call of Duty franchise. To an extent, maybe even Valorant and its usage of a spike.

We’re here to answer your questions! Let’s get to it!

A Brief History of the C4. Yes, the good old C4 explosive. Used by the military and by gamers alike! But how are they different when used in real life?

Whether you call it a C4 explosive, a C-4, the Composition C-4, or the M112 Demolition Block, it’s all the same. A C-4 explosive belongs to the RDX family of explosives that use hexahydro-1,3,5-triazine. Yes, I also think that’s too sciency, but regardless, it was first made in 1898 by the Germans(Not a surprise there).

Later on, it was patented by Edmund von Herz in the UK and the US in 1921 and 1922, respectively, and was later further developed to be used in World War II as a substitute for TNT. Its British counterpart is locally known as the PE-4 or the Plastic Explosive No. 4 simply because C4 is a plastic explosive.  It is not a “plastic” explosive because it contains plastics of course, plastic refers to it being soft and moldable into shapes.

C4 belongs to a family, just like us humans! It has brothers and sisters (otherwise called variants) called Composition C, C-2, and C-3. The Composition C variant was first used until 1943, when the C-2 replaced it, then replaced it again by the C-3 in 1944.
