Field Manual FM 4-40 Quartermaster Operations Change 1 April 2014 describes Quartermaster operations at all levels to include supply and field service functions. By reading this FM, commanders, staffs, and Soldiers will have an understanding of Quartermaster mission, organizations, and functions and will be better prepared to exercise them in an operational environment.More importantly, this field manual serves as the bridge between this force and the next, discussing units and systems that are being fielded now and into the near future, including Global Combat Support System - Army(GCSS-Army). While Army transformation to modularity is complete, our evolution will continue as we adjust the Army to new design for the Army of 2020. To support our force, we must focus ourselves on this new environment and apply the same innovation and professionalism that make us successful.
