Which principle of sustainment encompasses the protection of personnel, weapons, and supplies while deceiving the enemy?

The principle of sustainment that encompasses the protection of personnel, weapons, and supplies while deceiving the enemy is indeed survivability. This principle emphasizes the need to ensure that military forces can continue to operate effectively while also protecting critical resources and personnel from adversarial actions.

Survivability involves implementing measures to safeguard against threats, reducing vulnerabilities, and enhancing the ability to operate in contested environments. This includes physical protection, strategic deception, and readiness to adapt to changing circumstances on the battlefield. By focusing on survivability, forces can maintain a tactical advantage and sustain operations despite facing hostile conditions.

The other principles, while important, do not specifically address the dual need for protection and deception. Economy focuses on resource management and efficiency, continuity emphasizes maintaining operations over time, and improvisation encourages the ability to adapt creatively to unforeseen challenges. None of these capture the comprehensive approach to ensuring personnel and asset safety while misleading the enemy effectively as survivability does.
