What is the role of a Supernumerary in guard duty?

The role of a Supernumerary in guard duty primarily involves being prepared to replace a man on post when necessary. This position is critical to ensuring the continuity of guard duty, especially if a member of the guard becomes unable to continue their watch due to various reasons, such as illness or emergency situations. The presence of a Supernumerary ensures that there is always someone available to take over responsibilities on short notice, which maintains the effectiveness and vigilance of the guard.

This function is essential in maintaining operational security and ensuring that posts are never left unattended, reinforcing the overall integrity of the guard's mission. Thus, the role of a Supernumerary is not merely supportive but integral to the flow and effectiveness of guard duty operations.
