Field Manual (FM) 4-94 establishes Army doctrine for operational-level deployment and sustainment by providing overarching doctrinal direction for Army operations conducted in support of full spectrum operations detailed in other Army manuals. FM 4-93.4 also provides a foundation for the development of appropriate tactics, techniques, and procedures. FM 4-94 is comprised of six chapters. Chapter 1 discusses the TSC's role in full spectrum operations through discussions of the operational environment, theater structure, strategic level support organizations, and support to joint and multinational operations. Chapter 2 discusses the mission and organization of the TSC, the ESC, and subordinate organizations (including attached units). Chapter 3 discusses the automation and communication systems used to command and control operations. Chapter 4 discusses support operations to include distribution and materiel management, movement control, sustainment, and common-user logistics support. Chapter 5 discusses the strategic and joint interfaces that are required to optimize theater distribution. Chapter 6 discusses the TSC's role in protection. FM 4-94 provides operational guidance for commanders and staffs assigned to a numbered Army, an Army Service Component Command, a TSC headquarters and their subordinate units. This publication applies to the Active Army, the Army National Guard (ARNG)/the Army National Guard of the United States (ARNGUS), and the United States Army Reserve (USAR) unless otherwise stated.
