Before placing LS in remote, what must CM3 receive?

The correct answer is that before placing the Launcher System (LS) in remote, the Crew Member 3 (CM3) must receive permission from the Electronic Control System (EcS). In gunnery operations, communication and control systems are crucial for ensuring safe and effective operation of the weapons systems.

The EcS is responsible for overseeing the operational status and readiness of the launcher, validating that all systems are functioning properly and complying with safety protocols. By securing permission from the EcS, CM3 ensures that all necessary checks have been completed and that conditions are safe for transitioning to remote operation. This contributes significantly to the overall safety and effectiveness of military operations involving artillery systems.

While other personnel may have roles in the overall command and safety structure, their permissions are not specifically required for the action of placing the LS in remote, highlighting the importance of the EcS in this specific procedural step.
