The sustainment warfighting function is related tasks and systems that provide support and services to ensure freedom of action, extend operational reach, and prolong endurance (ADP 3-0). The endurance of Army forces is primarily a function of their sustainment. Sustainment determines the depth and duration of Army operations. Successful sustainment enables freedom of action by increasing the number and quality of options available to the commander. It is essential to retaining and exploiting the initiative. The sustainment warfighting function consists of three major elements: logistics, personnel services, and health service support.

Sustainment Warfighting Function

Elements of the Sustainment Warfighting Function

A. Logistics

Logistics is planning and executing of the movement and support of forces. It includes those aspects of military operations that deal with: design and development; acquisition, storage, movement, distribution, maintenance, and disposition of materiel; acquisition or construction, maintenance, operation, and disposition of facilities; and acquisition or furnishing of services. Explosive ordnance disposal is a function of logistics. However, EOD tasks are discussed under the protection warfighting function (Refer to FM 3-37 and ATTP 4-32). Logistics consists of the following:

• Maintenance (ATTP 4-33)
• Transportation (FM 55-1)
• Supply (FM 10-1)
• Field services (FM 10-1)
• Distribution (ATTP 4-0.1)
• Operational contract support (ATTP 4-10)
• General engineering support (FM 3-34)

See pp. 1-37 to 1-56 of SMFLS4: Sustainment & Multifunctional Logistics SMARTbook, 4th Ed. for further discussion.

B. Personnel Services

Personnel services are sustainment functions that man and fund the force, maintain Soldier and Family readiness, promote the moral and ethical values of the nation, and enable the fighting qualities of the Army. Personnel services provide economic power at the operational and tactical levels. Personnel services complement logistics by planning for and coordinating efforts that provide and sustain personnel. Personnel services consist of the following:

• Human resources support (FM 1-0)
• Financial management operations (FM 1-06)
• Legal support (FM 1-04)
• Religious support (FM 1-05)
• Band support (ATTP 1-19)

See pp. 1-57 to 1-66 of SMFLS4: Sustainment & Multifunctional Logistics SMARTbook, 4th Ed. for further discussion.

C. Health Service Support

Health service support encompasses all support and services performed, provided, and arranged by the Army Medical Department to promote, improve, conserve, or restore the mental and physical well being of personnel in the Army and, as directed, in other Services, agencies, and organizations (ATTP 4-02). Army Health System support includes both health service support and force health protection. The health service support mission is a part of the sustainment warfighting function. The force health protection mission falls under the protection warfighting function and will not be covered in this publication. Health service support consists of the following medical functions:

• Casualty care, which encompasses a number of Army Medical Department functions, to include —
– Organic and area medical support
– Hospitalization
– Dental care (treatment aspects)
– Behavioral health/neuropsychiatric treatment
– Clinical laboratory services
– Treatment of chemical, biological, radiological, and nuclear patients
• Medical evacuation
• Medical logistics
