Final answer:
The unique ASU coat sleeve ornamentation on enlisted personnel consists of rank insignia and unit patches that represent the soldier's rank and unit affiliation.
Step-by-step explanation:
The unique ASU coat sleeve ornamentation on enlisted personnel refers to the insignia or patches that are worn on the sleeves of soldiers' uniforms in the United States Army. These patches represent the soldier's rank and unit affiliation, and are placed on the left and right sleeves of the Army Service Uniform (ASU).
For enlisted personnel, the sleeve ornamentation includes the rank insignia, which consists of chevrons and arcs, and the unit patches. The rank insignia indicate the soldier's position in the enlisted hierarchy, while the unit patches identify the soldier's specific unit or division.
For example, a soldier in the Army might have a rank insignia of three chevrons and a rockers, which indicates the rank of Ser geant First Class (SFC), and a unit patch for the 101st Airborne Division, known as the Screaming Eagles.
