Army Doctrine Reference Publication (ADRP) 2-0 is the Army's reference publication for Army intelligence. It provides a common construct for intelligence doctrine from which Army forces adapt to conduct operations. It discusses: - Intelligence in unified land operations. - The purpose and role of intelligence. - Intelligence core competencies. - The intelligence warfighting function. - The intelligence enterprise. - The intelligence process. - Intelligence capabilities. The principal audience for ADRP 2-0 is every Soldier and those Army civilians who interact with the intelligence warfighting function. This publication is the foundation for the intelligence warfighting function and subsequent doctrine development. It also serves as a reference for personnel who are developing doctrine, leader development, materiel and force structure, and institutional and unit training for intelligence. Commanders, staffs, and subordinates ensure their decisions and actions comply with applicable U.S., international, and, in some cases, host-nation laws and regulations. Commanders at all levels ensure their Soldiers operate in accordance with the law of war and the rules of engagement. (See Field Manual FM] 27-10.) ADRP 2-0 uses joint terms where applicable.
