What does the sustainment warfighting function involve?

The sustainment warfighting function is fundamentally centered around ensuring that military operations can continue effectively and efficiently over time. It encompasses a range of tasks and capabilities that provide the necessary logistics, personnel support, maintenance, and supply needed to sustain forces in the field. This includes managing resources like fuel, ammunition, food, and medical care, all of which are critical for maintaining operational capability and readiness.

By focusing on supporting the ongoing operations and ensuring that troops remain ready to engage in combat or perform their missions, the sustainment warfighting function plays a vital role in the overall success of military operations. It emphasizes the importance of preparation and resource management in support of tactical and strategic objectives, ensuring that units can sustain themselves throughout the duration of their mission.

In contrast, options that focus on planning for combat execution, training soldiers for missions, and determining intelligence requirements pertain to different aspects of military operations—namely, combat operations planning, personnel readiness, and intelligence operations—rather than the sustainment function.
