Which set correctly identifies the four sustainment functions in Army doctrine?

• A. Supply, maintenance, transportation, and field services (including health service support).
• B. Planning, programming, budgeting, and execution.
• C. Operations, intelligence, security, and communications.
• D. Procurement, logistics, scheduling, and training.

Answer: (A)

Sustainment ensures forces have the material, maintenance, movement, and services they need to stay operational. The four sustainment functions are supply, maintenance, transportation, and field services (including health service support). Supply covers getting the right materiel to the right place at the right time—procurement, storage, distribution, and issue to units. Maintenance keeps equipment and systems ready through preventive, proactive, and remedial repairs so gear doesn’t fail in the field. Transportation handles moving personnel and equipment across the area of operations, ensuring timely arrival where needed. Field services pull together the non-weapon-support activities that keep soldiers fed, paid, cared for, and fit to fight, with health service support addressing medical care and evacuation among other welfare services. These four are the Army’s formal sustainment functions. The other options describe planning and budgeting processes, or different staff/war-fighting areas, and don’t map to the four sustainment functions as defined by doctrine.
