- ADP 2-0Publication
Intelligence
ADP 2-0 is the Army's foundational publication for the intelligence warfighting function.

It is the parent publication for the rest of the 2-series.
- ATP 2-01.3Publication
Intelligence Preparation of the Operational Environment
ATP 2-01.3 is the staff process for evaluating terrain, weather, civil considerations, and the threat in a specific operational environment. The 2019 edition renamed the process from intelligence preparation of the battlefield to intelligence preparation of the operational environment, and the posted file now incorporates change 3, dated May 2025. It is a whole-staff product, not just an S2 product.
- FM 5-0Publication
Planning and Orders Production
FM 5-0 is the Army's reference for planning: the military decision-making process, troop leading procedures, Army design methodology, and the formats for plans and orders. If you have ever needed the five-paragraph OPORD format at midnight, this is the book. The November 2024 edition supersedes the 16 May 2022 version and the posted file incorporates change 1, dated August 2025.
- TC 3-22.9Publication
Rifle and Carbine
TC 3-22.9 is the marksmanship publication for the M4- and M16-series weapons: how the weapon works, the functional elements of the shot process, and the training and qualification strategy. The posted file is the May 2016 basic publication incorporating changes 1 through 3, so work from the current file rather than a saved copy.
