Which action results in the greatest number of demerits?

Moving from assigned seating typically results in the greatest number of demerits because it signifies a disregard for the established structure and discipline within the drill team. Assigned seating is often a critical aspect of maintaining order and organization during practices and performances. It ensures that team members are located where they can best hear instructions and support one another. Deviating from assigned seating can disrupt the flow of practice, create confusion, and diminish the overall team cohesion.

The specific rules regarding seating assignments are usually put in place to promote unity and discipline, which are essential values in a drill team environment. In contrast, while not cheering with the team, talking to a non-team member, and improper stand conduct can draw penalties or demerits, they usually do not undermine the team's operational structure to the same extent that moving from assigned seating does. Therefore, the emphasis placed on adherence to seating arrangements makes this action warrant the most severe consequences.
