In which ranks are shoulder boards worn?

Shoulder boards are specific insignia worn by certain ranks in the Army to signify their position and authority. The correct range of ranks that wear shoulder boards includes Corporals through to the Sergeant Major of the Army, as well as all Officer ranks, which aligns with the correct answer.

This design choice helps maintain a clear distinction between enlisted ranks and officers, as shoulder boards are traditionally associated with officers in many branches of the military. Additionally, this system allows for uniform identification of leadership within the ranks, enhancing both organizational structure and peer recognition.

The rationale for the incorrect options lies in their limitations on the rank range. For instance, claiming that shoulder boards are only worn from Private to Sergeant or exclusively by officers fails to encompass the full scope of ranks authorized to wear these insignia, thereby misrepresenting the guidelines in uniform wear.
