Pin-on metal Second Lieutenant cap rank insignia is available in Full and Miniature sizes. Second Lieutenants wear the Full size version on the men's or women's Flight Cap (women are authorized to wear either). The insignia is positioned on the wearer’s left side of the Flight Cap, centered between the bottom of the cap and the crease at the top, 1 1/2-inch from the flight cap’s front edge. Insignia bars (Lieutenants and Captain) are oriented so that the long axis is vertical. The USAF Flight Cap is worn only with the Service, Service Dress, Flight/Desert Flight Duty, and Air Force Food Services uniform.

Colored berets include maroon (Pararescue Personnel and Combat Rescue Officers), pewter green (Survival, Evasion, Resistance, Escape), scarlet (Combat Control Team and Special Tactics Officers), pewter gray (Weather Parachutists), Air Liaison Officers and Tactical Air Control (black).
