The centerline of the U.S. insignia disk must be parallel to which edge of the lapel?

• A. The outside edge of the lapel.
• B. The notch on the lapel.
• C. The belt buckle.
• D. The inside edge of the lapel.

Answer: (D)

Aligning the insignia’s centerline with the inside edge of the lapel provides a consistent, clean reference that keeps the disk level with the torso and the jacket’s natural lines. The inside edge runs closest to the center of the coat, so using it as the reference ensures proper, symmetrical placement from any angle. Aligning with the outside edge, the notch, or the belt buckle would tilt or misplace the emblem, which is not in line with standard uniform appearance. Therefore, the centerline should be parallel to the inside edge.
