ADP 3-37 — Protection
Army Doctrine Publication 3-37 defines the protection warfighting function — how Army forces preserve combat power by protecting personnel, equipment, facilities, and information from threats across all domains.
Current edition: 06 April 2026
Questions are based on this version. If your copy shows a newer date, let us know — we'll update the question bank.
18 protection warfighting function tasks (including the 2026 additions of cyber/EW and space operations support), five protection principles, critical asset list (CAL), defended asset list (DAL), scheme of protection, CBRN defense, survivability operations, fratricide avoidance, and protection planning.
ADP 3-37 is the April 2026 edition — the most current version. Boards will ask about the 18 protection tasks and the five principles. The 2026 edition added cyber/EW and space operations support as protection tasks — candidates still citing the 2019 list of 16 tasks will get it wrong. This question bank reflects the current edition.
