Which of the following describes the standard Surface Danger Zone (SDZ) for small arms?

The standard Surface Danger Zone (SDZ) for small arms is best described as a cone and bat wing shape. This design provides a practical approach to understanding the potential trajectory of bullets and their impact areas, which may vary based on the type of firearm and the angle of fire. The conical shape extends outward from the shooter’s position and takes into account the height of projectiles above the ground, providing critical information for establishing safe boundaries around shooting ranges.

The concept of the "bat wing" illustrates the expansion of the danger zone as distances increase from the point of origin. This is particularly important for range safety officers and crew as it helps in planning and ensuring that no unauthorized personnel enter areas where live fire is taking place. By understanding this layout, range management can effectively communicate danger areas, ensuring safety for all involved.
