What principle of sustainment refers to the uninterrupted provision of support across all levels of war?

The principle of sustainment that refers to the uninterrupted provision of support across all levels of war is continuity. This concept emphasizes the importance of maintaining consistent and reliable support for military operations to ensure they can sustain their efforts without interruption. Continuity ensures that logistical and operational needs are met seamlessly, allowing forces to focus on their mission without the disruptions that may occur from lapses in support. This principle is essential for effective military operations, as it allows units to operate effectively in various combat scenarios, maintaining momentum and operational readiness.

Survivability focuses on the ability of military units to resist damage and survive combat situations, while economy pertains to using resources in a manner that maximizes effectiveness and minimizes waste. Simplicity involves the ease of understanding and executing plans and operations. While these principles play vital roles in sustainment, it is continuity that specifically addresses the need for uninterrupted support across all levels of warfare.
