What is the minimum safe firing distance for an M320 with High Explosive rounds in combat?

The minimum safe firing distance for an M320 with High Explosive rounds is 30 meters. This distance is established to ensure safety from the blast and fragmentation effects that occur when a high explosive round detonates. It is crucial for troops to maintain this distance to minimize the risk of injury from unintended consequences of the explosion, such as shockwaves and shrapnel.

Understanding the specifics of safe firing distances is vital for operational effectiveness in combat scenarios, where troops must manage the balance between effective engagement of targets and the safety of friendly forces. While the other options present further distances, they would exceed the operational guidelines established for effective weapon use under standard combat conditions.
