What does the Cone Surface Danger Zone (SDZ) contain?

The Cone Surface Danger Zone (SDZ) refers to a defined area where various dangers associated with munitions can occur during operations. The correct answer highlights that this zone contains not only ricochets and fragments but also rounds and debris.

Ricochets occur when projectiles or fragments bounce off hard surfaces and can strike unintended targets. Fragments are often produced when rounds detonate, scattering pieces in a defined area. Rounds refer to the actual live ammunition that has not yet detonated but is in the trajectory of the firing. Debris can include all sorts of materials that may be expelled into the area during firing, such as pieces from the environment or ammunition components. Understanding the full scope of what is included in the Cone SDZ is critical for ensuring safety measures are put in place to protect personnel and equipment outside of this area from all potential hazards related to munitions.

Other options are limited in scope, failing to capture the variety of potential dangers present in the SDZ, which is important for comprehensive range safety planning.
