Which rank is represented by two stripes and a star?

The rank represented by two stripes and a star signifies the position of Airman 1st Class. In the United States Air Force, the rank of Airman 1st Class is characterized by this specific insignia.

This rank serves as a recognition of the airman's advancement and increasing responsibilities compared to lower ranks. As personnel progress through the ranks, they not only gain additional pay but are also expected to demonstrate increased proficiency, leadership potential, and a deeper understanding of their roles within the Air Force. The silver star on the insignia marks the distinction of being an Airman 1st Class, as opposed to Airman (which has no stripes) or Airman Basic (which is also represented by no stripes). Senior Airman, while similarly close in rank designation, is indicated by three stripes and a star, thus distinguishing it from Airman 1st Class.
