Which principle of sustainment refers to the integration of logistics, personnel services, and health service support?

The principle of sustainment that refers to the integration of logistics, personnel services, and health service support is indeed integration. This principle emphasizes the necessity of creating a cohesive system where various components of sustainment work together seamlessly. Integration ensures that logistics—such as supply chain management and transportation—are not isolated but are effectively coordinated with personnel services, which encompass the management of soldiers, and health service support, which focuses on maintaining the health and welfare of the force.

By promoting integration, military operations can achieve greater efficiency and effectiveness, allowing all facets of sustainment to align and respond dynamically to mission requirements. This holistic approach is essential for maintaining operational readiness, as it enables quick adaptation to changing situations and resource availability, thereby enhancing overall mission success. The function of integration is foundational for ensuring that sustainment operations do not operate in silos but rather contribute to a unified effort supporting the armed forces' capabilities.
