Which of the following items is NOT authorized for enlisted Sailors to wear in uniform?

The item that is not authorized for enlisted Sailors to wear in uniform is pilot wings. While pilot wings are worn by officers who have completed the necessary training and qualifications, enlisted personnel are not authorized to wear them as part of their uniform.

In contrast, parachutist wings, aircrew wings, and the SEAL trident are all authorized for enlisted Sailors. Parachutist wings are awarded to Sailors who have successfully completed parachute training, aircrew wings are given to those who serve as aircrew members, and the SEAL trident represents successful completion of training as a Navy SEAL, which is specific to enlisted personnel who have earned that honor. Understanding the differences in qualifications and the corresponding insignia is important in recognizing what is appropriate for different ranks and roles within the Navy.
