[1682]. Whenever it becomes necessary for the corporal to leave his post near the entrance of the guardhouse, he will notify the sergeant of the guard, who will at once take his place, or designate another noncommissioned officer to do so. (120)
[1683]. He will see that no person enters the guardhouse, or guard tent, or crosses the posts of the sentinels there posted without proper authority. (121)
[1684]. Should any sentinel call for the corporal of the guard, the corporal will, in every case, at once and quickly proceed to such sentinel. He will notify the sergeant of the guard before leaving the guardhouse. (122)
[1685]. He will at once report to the commander of the guard any violation of regulations or any unusual occurrence which is reported to him by a sentinel, or which comes to his notice in any other way. (123)
[1686]. Should a sentinel call: "The Guard," the corporal will promptly notify the commander of the guard. (124)
[1687]. Should a sentinel call: "Relief," the corporal will at once proceed to the post of such sentinel, taking with him the man next for duty on that post. If the sentinel is relieved for a short time only, the corporal will again post him as soon as the necessity for his relief ceases. (125)
[1688]. When the countersign is used, the corporal at the posting of the relief during whose tour challenging is to begin gives the countersign to the members of the relief, excepting those posted at the guardhouse. (126)
[1689]. He will wake the corporal whose relief is next on post in time for the latter to verify the prisoners, form his relief, and post it at the proper hour. (127)
[1690]. Should the guard be turned out, each corporal will call his own relief, and cause its members to fall in promptly. (128)
[1691]. Tents or bunks in the same vicinity will be designated for the reliefs so that all the members of each relief may, if necessary, be found and turned out by the corporal in the least time and with the least confusion. (129)
