The Modular Force — FMI 3-0.1

This publication describes why and how the Army is changing its warfighting doctrine, organizations, training, and operations. It summarizes the reasons for changes and describes the principles underlying Army transformation. It also explains how those principles shape ongoing change and describes projected changes for the Army in the next two decades. This publication is an updated and abridged edition of the Army Comprehensive Guide to Modularity re-leased in October 2004. Since then, the modular force has evolved, and understanding of its employment has improved.
