=107.= Each corporal will then make a list of the members of his relief, including himself. This list will contain the number of the relief, the name, the company, and the regiment of every member thereof and the post to which each is assigned. The list will be made in duplicate, one copy to be given to the sergeant of the guard as soon as completed, the other to be retained by the corporal. =108.= When directed by the commander of the guard, the corporal of the first relief forms his relief, and then commands: =CALL OFF=. Commencing on the right, the men call off alternately =rear= and =front rank=, "one," "two," "three," "four," and so on; if in single rank, they call off from right to left. The corporal then commands: 1. =Right=, 2. =FACE=, 3. =Forward=, 4. =MARCH.= The corporal marches on the left and near the rear file in order to observe the march. The corporal of the old guard marches on the right of the leading file, and takes command when the last one of the old sentinels is relieved, changing places with the corporal of the new guard. =109.= When the relief arrives at six paces from a sentinel (see par. 168), the corporal halts it and commands, according to the number of the post: =No. (----)=. Both sentinels execute port arms or saber; the new sentinel approaches the old, halting about one pace from him. (See par. 172.) =110.= The corporals advance and place themselves, facing each other, a little in advance of the new sentinel, the old corporal on his right, the new corporal on his left, both at a right shoulder, and observe that the old sentinel transmits correctly his instructions. The following diagram will illustrate the positions taken: [Illustration: A R - | | | | | C| |D | | | | - B] R is the relief; A, the new corporal; B, the old; C, the new sentinel; D, the old. =111.= The instructions relative to the post having been communicated, the new corporal commands, =Post=; both sentinels then resume the right shoulder, face toward the new corporal, and step back so as to allow the relief to pass in front of them. The new corporal then commands: "1. =Forward=, 2. =MARCH="; the old sentinel takes his place in rear of the relief as it passes him, his piece in the same position an those of the relief. The new sentinel stands fast at a right shoulder until the relief has passed six paces beyond him, when he walks his post. The corporals take their places as the relief passes them. =112.= Mounted sentinels are posted and relieved in accordance with the same principles. =113.= On the return of the old relief, the corporal of the new guard falls out when the relief halts; the corporal of the old guard forms his relief on the left of the old guard, salutes, and reports to the commander of his guard: "=Sir, the relief is present="; or "=Sir, (so-and-so) is absent=," and takes his place in the guard.
