Field Manual (FM) 31-20 is the Special Forces (SF) principles manual. It is directly linked to and must be used in conjunction with the doctrinal principles found in FMs 100-5 and 100-20 and the projected FM 100-25. It describes SF roles, missions, capabilities, organization, command and control, employment, and support across the operational continuum and at all levels of war. It provides the authoritative foundation for SF subordinate doctrine, force design, materiel acquisition, professional education, and individual and collective training. It supports the doctrinal requirements of the Concept Based Requirements System.
This manual provides the doctrinal principles to plan and prepare SF operational elements for commitment and to direct and sustain those elements after commitment. The user must adapt the principles presented here to any given situation using his own professional knowledge, skills, and judgment. Because this manual articulates the collective vision of the senior SF leadership, users must understand that it describes emerging doctrinal requirements as well as current operational capabilities.
This manual is unclassified to ensure its Armywide dissemination and the integration of SF into the Army's systems. As the preparing agency for this manual and all SF doctrinal and training publications, the US Army John F. Kennedy Special Warfare Center and School (USAJFKSWCS) will publish a series of subordinate field manuals to disseminate the specific SF tactics, techniques, and procedures (TTP) necessary to plan and conduct SF operations.
