What type of explosive filler does an M26 fragmentation grenade have?

The M26 fragmentation grenade utilizes Composition B as its explosive filler. Composition B is a mixture of RDX (Research Department Explosive) and TNT (Trinitrotoluene), specifically designed to maximize the explosive output while minimizing sensitivity. This combination not only allows for a high detonation velocity but also ensures that the grenade produces effective fragmentation upon detonation, which is essential for maximizing the lethality and dispersal of shrapnel in a combat scenario.

In the context of military ordnance, understanding the specific composition of explosives like the filler in the M26 grenade is crucial for assessing its effectiveness in various operations and understanding its performance characteristics in different environments.
