Inventory of Field Manuals as of Jan 23, 2002 [PDF] Inventory of Field Manuals as of Jun 21, 2001 [PDF] Doctrine 2015 Information Briefing [PDF] As part of the Army's Doctrine 2015 initiative, Field Manuals (FMs) would continue to serve as the most comprehensive reference manuals in the new series of doctrine documents, which also included Army Doctrine Publications (ADPs) and Army Doctrine Reference Republications (ADRPs). The total number of FMs, however, would be reduced to 50, covering core concepts and the FMs would be limited to a main body text of no more than 200 pages. All remaining knowledge would be transitioned to a new lower-level series of publications, called Army Techniques Publications (ATPs).
