The inspection which corresponds to that of par. 882 being ended, and the officers of the day, the adjutant, and the commander of the guard having taken their posts, the commander of the guard draws saber with the adjutant and comes to the order. The adjutant then commands: 1. =Parade=, 2. =Rest=, 3. =SOUND OFF=, and comes to the _order_ and _parade rest_. (_e_) After the band has sounded off, the adjutant, commander of the guard, and platoon leaders come to attention, and the adjutant commands: 1. =Present=, 2. =ARMS=, faces toward the officer of the day and reports: _Sir, the guard is formed._ The new officer of the day, after the adjutant has reported, returns the salute with the hand and directs the adjutant: _March the guard in review, Sir._ The adjutant carries saber, faces about, brings the guard to an order and commands: 1. =At trail, platoons (or guard) right turn=, 2. =MARCH=; 3. =Guard=, 4. =HALT.= The guard marches in quick time past the officer of the day, according to the principles as when mounted. While the band is sounding off and while the guard is marching in review, the officers of the day stand at parade rest with arms folded. They take this position when the adjutant comes to parade rest, resume the attention with him, again take the parade rest at the first note of the march in review, and resume attention as the head of the column approaches.

Relieving the Old Guard.= =360.= As the new guard approaches the guardhouse, the old guard is formed in line, with its field music three paces to its right; and, when the field music at the head of the new guard arrives opposite its left, the commander of the new guard commands: 1. =Eyes, RIGHT=; the commander of the old guard commands: 1. =Present=, 2. =ARMS=; commanders of both guards salute. The new guard marches in quick time past the old guard. When the commander of the new guard is opposite the field music of the old guard, he commands: =FRONT=; the commander of the old guard commands: 1. =Order=, 2. =ARMS=, as soon as the new guard shall have cleared the old guard.
