For which of the following duties is a sentry not responsible according to the General Orders?

A sentry's responsibilities according to the General Orders include receiving and obeying orders, saluting all officers, and calling a petty officer if they are unsure about a situation. These duties ensure that the sentry maintains proper protocol and communication while on duty.

The statement regarding quitting the post if feeling unsafe is not a responsibility outlined in the General Orders. A sentry is expected to remain at their post unless properly relieved or given specific orders to do otherwise. If a sentry finds themselves in a situation they perceive as unsafe, they must follow the proper chain of command and procedures rather than abandoning the post. This is crucial for maintaining security and order, as leaving a post without authorization has the potential to compromise safety and security measures in place.
