Who has the overall responsibility for operations during an HLZ?

The overall responsibility for operations during a helicopter landing zone (HLZ) falls to the commander of the unit or mission, known as the commanding officer (CO). The CO makes critical decisions regarding the conduct of operations within the HLZ, ensuring coordination between various elements involved, such as ground forces and aviation assets. This role includes overseeing safety, strategic landing procedures, and operational effectiveness, making it essential for the success of the mission and the safety of personnel.

The other roles mentioned, such as the radio telephone operator (RTO), the PZ control officer, and the chalk-linkup guide, each have specific duties within HLZ operations but do not hold the comprehensive command responsibility that the CO possesses. The RTO facilitates communication, while the PZ control officer manages the personnel drop zone. The chalk-linkup guide assists in coordinating the movement of troops. However, it is the CO who is ultimately in charge of overseeing and directing all activities during HLZ operations.
