Final answer:
The lowest deviation authority authorized by AR 385-63 to permit non-participating personnel within the Surface Danger Zone (SDZ) during Army training is usually a range control officer. This individual has the responsibility to ensure safety and adherence to regulations while considering deviation requests.
Step-by-step explanation:
The question is asking who the lowest authority is, as per AR 385-63, that can approve deviations allowing non-participating personnel access within the Surface Danger Zone (SDZ) during Army training.
Within the context of Army regulations, deviations of this nature could significantly impact safety and training protocols.
AR 385-63 provides policies and procedures for the use of weapons and munitions by the Army and prescribes the operational requirements to ensure safety measures are followed.
The lowest deviation authority according to AR 385-63 is typically a range control officer or a comparable authority who has been delegated the power to approve such deviations.
This individual would assess the potential risks and determine whether the deviation would be allowed based on the specifics of the situation, training requirements, and safety considerations.
