What is the proper kill radius of an 81mm HE round?

The proper kill radius of an 81mm High Explosive (HE) round is generally recognized as 34-38 meters. This range is established based on the explosive characteristics and fragmentation patterns of the round, which are designed to effectively neutralize targets within that distance. Beyond this radius, the effectiveness of the blast and fragmentation is significantly reduced, making it increasingly unlikely to achieve lethal effects on personnel. Understanding the kill radius is crucial for infantry units to effectively plan and execute fire support while minimizing the risk to friendly forces and non-combatants in the area of operations. Therefore, selecting the correct kill radius is fundamental for operational planning and achieving mission success.
