Which behavior incurs 5 to 15 demerits?

The behavior that incurs 5 to 15 demerits is the failure to show respect. This is significant in a drill team or any disciplined organization because respect among team members fosters a positive environment and promotes teamwork. If individuals do not demonstrate respect towards each other or their leadership, it can create tension, hinder collaboration, and disrupt the overall harmony of the group. Therefore, implementing a system of demerits for this behavior underscores the organization's commitment to maintaining a respectful and supportive atmosphere, which is crucial for the success of any team-oriented activity.

The other behaviors listed, while they may also warrant consequences, are typically categorized differently or might incur a different range of demerits based on their severity or impact on the team dynamic. Hence, the specific point value assigned to the failure to show respect highlights its importance in maintaining a positive team culture.
