Pin-on metal Air Force Officer rank insignia is offered in two sizes, Full and Miniature.
As Field Grade Officers, Colonels wear the Full-size pin-on metal rank insignia on the left side (viewer’s right) of a Flight Cap featuring a blue and silver braid along the overlapping edge. Oriented so the eagle is facing forward and the insignia is roughly centered vertically between the braid and the bottom of the cap, the insignia is placed so that its foremost edge is 1-1/2 inches from the front crease of the cap.
The miniature metal rank insignia is authorized for wear by Officers serving in specially designated units in which all personnel are authorized to wear a colored beret. These are listed in
Section A7.7 Miscellaneous Uniforms of Attachment 7 of the Air Force Guidance Memorandum to AFI 36-2903,
Dress and Personal Appearance of Air Force Personnel (June 2021). This section also includes detailed guidance on the placement of miniature rank insignia on berets.
