GEN Wallace in the Mar-Apr 08 Military Review:

FM 3-0 Operations: The Army's Blueprint
....The 2008 edition of FM 3-0, though shorter in length than its predecessors, presents the fundamental principles and concepts that guide the direction of Army operations rather than a checklist for success. Significant recent operational experience from the War on Terror, specifically the operations in Afghanistan, Iraq, and the Philippines, as well as urgent relief efforts following Hurricane Katrina and Rita, necessitated changes in doctrine. The development of this version of FM 3-0 traces back to 2005 with a series of issue papers covering unified action, the design of the war fighting functions, the continuum of operations, and the Army’s operational concept. The collective thoughts poured into and resulting from the issue papers served as a structural foundation for codifying the key concepts of the manual. The FM 3-0 issue papers were staffed to a broad audience of over 200 organizations, media groups, and individual recipients. The major organizations included the Army Staff; Army commands; Army service component commands; Army corps and division headquarters; training divisions; and TRADOC commands and centers, proponents, and staff, as well Air Force, Marine, and Navy doctrine centers. The discussion generated from the issue papers led to a draft of the content summary that served as guide for the overall layout of the themes, concepts, and chapter structure of the field manual.

The Combined Arms Doctrine Directorate hosted three action-officer-level councils of colonels in an effort to synthesize and integrate over 4,000 comments from various entities in the field at large across three drafts of the manual to coalesce as much expert knowledge, thought, and current operational experience as possible. The meetings provided a separate forum for fostering debate, gaining consensus, and resolving critical and major comments from respective reviewing agencies prior to a TRADOC commander-hosted doctrine and concepts conference.

The latest iteration of FM 3-0 is evolutionary in nature, incorporating ideas from new joint doctrine while retaining those valued pieces of Army doctrine that have stood the test of time. However, the doctrine is revolutionary with respect to its impetus and momentum to drive change. FM 3-0 provides purpose and direction to Army transformation and the application of force in complex operational environments. The current edition of FM 3-0 reflects Army thinking in a complex era of persistent conflict. The doctrine recognizes that military force alone will not resolve this type of conflict. Dominant landpower, while vital to operations, represents only one element of a broader campaign that requires the application of each element of national power. In line with this realization and reasoning, Army doctrine now elevates stability or civil-support operations to equal importance with offensive and defensive operations.....
