Since then, the most important doctrine have been published in Army Doctrine Publications (ADP) and Army Doctrine Reference Publications (ADRP), replacing the former key Field Manuals. Army Techniques Publications (ATP), Army Training Circulars (TC), and Army Technical Manuals (TM) round out the new suite of doctrinal publications. Not all FMs are being rescinded; 50 select Field Manuals will continue to be published, periodically reviewed and revised.
