Little blue book
Master Sgt. Joseph Beymer, 21st Comptroller Squadron first sergeant, hands out “The Little Blue Book,” Air Force Instruction 1-1, which discusses Air Force culture and Air Force standards, to (clockwise) Senior Airman Brandon Bennett, Airman 1st Class Kelvin Smith, Staff Sgt. Ryan Sison, Senior Airman Joshua Thomas, and Staff Sgt. James Blaz. AFI 1-1 took a majority of the general rules and regulations Airmen need to know from other AFIs and incorporated them into a quick reference booklet that can be carried with them. “Little blue books” are available from unit first sergeants.
