Which two publications provide detailed information on lightning protection systems?

The publication that is most relevant for detailed information on lightning protection systems is DA PAM 385-64. This pamphlet provides guidance on safety principles related to ammunition and explosives safety, including the implementation and details of lightning protection measures specifically tailored for military applications. Such guidance is essential for ensuring that facilities and personnel are protected from the hazards associated with lightning strikes, particularly in environments where explosives are present.

While NFPA 780 is also a key document that addresses lightning protection systems, particularly in general safety contexts beyond the military, the question specifically requires the identification of publications pertinent to Army operations. DA PAM 385-64 is tailored for Army needs, making it the most suitable answer in this context.

FM 795 and AR 700-5 relate to different aspects of military operations and logistics, so they do not focus on lightning protection systems in detail. Understanding the purpose and focus of these various documents helps clarify why DA PAM 385-64 is the correct choice.
