116.  To dismiss the old relief, it is halted and faced to the front at the guardhouse by the corporal of the new relief, who then falls out; the corporal of the old relief then steps in front of the relief and dismisses it by the proper commands.

117.  Should the pieces have been loaded before the relief was posted, the corporal will, before dismissing the relief, see that no cartridges are left in the chambers or magazines.  The same rule applies to sentinels over prisoners.

118.  Each corporal will thoroughly acquaint himself with all the special orders of every sentinel on his relief, and see that each understands and correctly transmits such order in detail to his successor.

119.  There should be at least one noncommissioned officer constantly on the alert at the guardhouse, usually the corporal whose relief is on post.  This noncommissioned officer takes post near the entrance of the guardhouse, and does not fall in with the guard when it is formed.  He will have his rifle constantly with him.

120.  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.

121.  He will see that no person enters the guardhouse or guard tent, or crosses the posts of the sentinels there posted without proper authority.

122.  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.

123.  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.

124.  Should a sentinel call “The Guard,” the corporal will promptly notify the commander of the guard.

125.  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.

126.  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.

127.  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.

128.  Should the guard be turned out, each corporal will call his own relief, and cause its members to fall in promptly.

129.  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.
