In which situation should the corporal of the guard be called?

The corporal of the guard should be called in any case not covered by instructions because this ensures that there is a clear chain of command and that all situations are handled appropriately according to established protocols. This option emphasizes the importance of leadership and the need to escalate issues that fall outside the scope of routine procedures.

Calling the corporal in these instances helps maintain security and discipline within the unit, as they are trained to handle unexpected situations and can make informed decisions based on their experience. This ensures that even when protocols do not directly address a particular scenario, there is still a designated authority to manage the situation effectively, maintaining the safety and security of the area and personnel involved.
