Airman Basic is the only Air Force rank that has no insignia affiliated. The lack of uniform insignia for Airmen Basic is the impetus for the nickname "slick-sleeve", in contrast to all other enlisted Air Force ranks which wear their stripes/chevrons on their uniform sleeves.
The term of address for an Airman Basic is "Airman Basic", "Airman", or "AB".
