Which warfighting function provides support and services to ensure operational reach and endurance?

• A. Movement and maneuver
• B. Sustainment
• C. Protection
• D. Fires

Answer: (B)

The main idea here is that operations depend on a logistics and support system that keeps forces supplied, repaired, transported, and cared for so they can reach distant objectives and endure over time. Sustainment covers all of these services, from fueling and feeding troops to maintaining equipment, moving supplies, and providing medical and personnel support. By ensuring a continuous flow of resources and services, it extends how far and how long a force can operate—its operational reach and endurance. Movement and maneuver focuses on how forces are deployed and positioned to achieve goals; protection is about safeguarding forces; fires are about delivering combat power. None of those by themselves guarantee that a force can stay in the fight for an extended period or operate far from its base, which is precisely what sustainment enables.
