What is worn by cadets commanding or leading a drill team or other groups?

The correct choice, indicating what is worn by cadets commanding or leading a drill team or other groups, reflects the significance of the gold anchor. The gold anchor is a symbol of leadership and authority within the NJROTC program. It signifies that the cadet has achieved a level of responsibility and is recognized for their ability to lead their peers during drills and other formations.

This distinction is important in a military training context, as it sets apart cadets who have demonstrated the skills and qualities necessary for effective command. The gold anchor symbolizes not just rank or title but also the commitment to leadership and excellence that is expected from those in command positions.

In contrast, other options such as a gold medal, gold star, or gold cord may signify achievements or honor but do not specifically represent the role of a leader in a drill team. Thus, the gold anchor is the most appropriate and recognized insignia for cadets leading others in a drill or similar activities.
