FM 4-0 Sustainment Operations

FM 4-0, Sustainment Operations, augments the Army's principal doctrine on providing sustainment support as found in ADP 4-0. It describes how Army sustainment forces, as part of a joint team, provide support to Army and other forces with particular emphasis on support to large-scale combat operations. This manual is a companion manual to FM 3-0 on Army operations and, together with ADP 4-0, provides the foundation for how Army sustainment forces support prompt and sustained large-scale combat operations.
