Who is normally a senior non-commissioned officer with superior knowledge of COD functions and responsibilities?

The correct choice refers to the Senior Operations Duty Officer Technician (SODOT), who is typically a senior non-commissioned officer with extensive knowledge of Combat Operations Division (COD) functions and responsibilities. This role is critical for ensuring that operations run smoothly and efficiently, as the SODOT is responsible for overseeing the execution of plans and procedures related to military operations. The experience and expertise of the SODOT enable them to provide guidance and make informed decisions during operations, which is vital for maintaining the effectiveness of the unit.

In contrast, the other options do not fit the criteria of being a senior non-commissioned officer with specialized knowledge in COD functions. The Staff Operations Duty Officer (SODO) also has responsibilities related to operations but usually operates at a different level or focus than the SODOT. The reference to "WD" and "NORAD" pertains to different entities or roles that do not align with the specific responsibilities and designation of a senior non-commissioned officer within the context of COD operations.
