Which of the following is NOT part of the DLSS chain of command?

The correct understanding of the chain of command within the Diver Life Support System (DLSS) indicates that roles are established to ensure proper oversight, administration, and support for diving operations. The chain typically consists of positions that play crucial roles in the management and operation of diver support systems.

A system sponsor plays a vital role in policy and funding decisions, ensuring the systems are sustained and properly implemented. The diving officer is directly responsible for diving operations, safety, and overseeing the application of diving strategies and procedures. The applicant is an individual seeking to participate in diving programs, who must meet specific qualifications and undergo training.

The logistics officer, while important in many operational contexts, typically does not fit within the established DLSS chain of command. Their role is more supportive and auxiliary, dealing with the coordination and management of resources rather than being directly integrated into the command structure responsible for diving operations. Therefore, identifying them as not part of the DLSS chain of command is accurate as it reflects their more supportive and facilitative function in comparison to the more command-oriented roles of the other positions noted.
