What document outlines the preparation and updating of SDZs for all munitions and lasers?

The document that outlines the preparation and updating of Surface Danger Zones (SDZs) for all munitions and lasers is DA PAM 385-63. This publication provides guidelines and procedures specifically addressing safety related to the use of live fire and non-live fire training, including the necessary considerations for creating and maintaining SDZs.

DA PAM 385-63 serves as a comprehensive source, ensuring that all training exercises involving munitions and lasers are conducted safely, and it details the factors that need to be considered in the creation of SDZs, which include the types of ordnance being used, the environment of the training area, and the potential hazards to personnel and surrounding areas.

While other options mentioned, such as AR 385-63 and various directives, provide related information on safety and risk management within military operations, they do not specifically focus on the preparation and updating of SDZs, which is explicitly covered in DA PAM 385-63. This targeted scope is why it is the correct choice for this question.
