Which statement is true about the First Sergeant insignia?

• A. It is indicated by a diamond in the upper blue section of the chevron.
• B. It is indicated by a stripe on the sleeve.
• C. It is indicated by a circle around the insignia.
• D. It is indicated by a star on the shoulder.

Answer: (A)

First Sergeant is identified by a diamond shape placed in the blue area of the insignia on the sleeve. That diamond, or lozenge, is the distinctive mark that sets this position apart from other noncommissioned officers, signaling the role of senior enlisted leadership at the company level. A plain stripe markings belong to other ranks, a circle around the insignia isn’t used for this insignia, and a star on the shoulder is associated with different high-ranking appointments, not First Sergeant. So the diamond in the upper blue section of the chevron is the telling feature.
