When using steel targets during a firing exercise, what should be adjusted to account for potential misses?

The appropriate adjustment when using steel targets during a firing exercise is to modify the Safety Distance Zone (SDZ). The SDZ is a critical aspect of range safety, as it establishes boundaries to safeguard personnel and equipment from hazards associated with live fire exercises, particularly from ricochets that can occur when bullets strike steel targets.

When steel targets are engaged, the potential for misses or errant shots increases the need to ensure that the SDZ is adequately sized to account for these risks. Adjusting the SDZ allows for a safety margin that protects personnel and minimizes the risk of injury or damage from projectiles that may bounce back or veer off in unintended directions.

In contrast, impact media, personnel briefing, and ammunition type do not primarily address the safety concerns associated with misses when using steel targets. Impact media deals with the material used to stop or reduce the risk of ricochets in certain scenarios; personnel briefing ensures that all participants are aware of safety protocols but doesn’t change the physical safety zone. Adjusting ammunition type could potentially alter the impact dynamics but doesn't directly affect the layout for safety during a live-fire exercise. Therefore, the correct focus is on the Safety Distance Zone to ensure comprehensive protection in the range environment.
