Which of the following is NOT a responsibility of a CACO?

The role of a Casualty Assistance Calls Officer (CACO) primarily involves supporting the families of service members who are casualties. This encompasses a range of responsibilities aimed at assisting families in their time of loss and ensuring they receive the necessary support from the Marine Corps.

Notifying the family of a casualty is a critical responsibility that a CACO fulfills, as timely and compassionate communication is essential during such a difficult time. Facilitating memorial services is also a key task for a CACO, helping the family to honor their loved one and to navigate the arrangements involved. Ensuring communication between the family and the Marine Corps is vital in providing updates and assistance, so the family feels supported and informed throughout the process.

In contrast, the responsibility of providing updates on troop movements does not fall under the CACO’s duties. This task is related to operational military functions and is managed through other channels within the military structure. CACOs focus on casualty assistance and family support rather than ongoing military operations, making this option the correct answer as it does not align with the CACO's responsibilities.
