USAF HONOR GUARD NAVY BLUE AIGUILLETTE
In the United States Air Force, silver aiguillettes are reserved for wear by special personnel such Arlington National Cemetery Chaplains and members of Honor Guards (USAF and Base), Drill Teams, Color Guards, and Military Funeral Details.
Shoulder cords and aiguillettes in other colors, on the other hand, are used to indicate Air Force personnel who are serving as training leaders. Navy blue shoulder cords and aiguillettes are worn by Air Force personnel who have volunteered to serve on a Base Honor Guard and have reached a certain level of proficiency (executing roughly 30 different movements with minimal errors). The cords and aiguillettes are viewed as a sign of dedication and commitment to the Base Honor Guard, aiguillette wearers also train new volunteers. Shoulder cords and aiguillettes are worn until the member passes a final, more stringent evaluation and is issued Base Honor Guard Brassards.
Aiguillettes are worn the Blue Service and Mess Dress jackets, while shoulder cords are worn with all authorized utility uniform combinations.
