What does "frag" refer to in munitions terminology?

In munitions terminology, "frag" specifically refers to fragmentation resulting from the detonation of a munition. This term is commonly used in the context of explosives and munitions where the explosive device, upon detonation, produces debris or shrapnel that can cause damage to targets and personnel in the vicinity. The ability of a munition to generate fragmentation is a critical aspect of its lethality and effectiveness, especially in scenarios where area effects are desired. The fragments can vary in size and velocity, impacting a wide area, which is a significant consideration in combat scenarios. Understanding the concept of fragmentation helps in analyzing the operational impact of different munition types and their deployment in various environments.
