714. After saluting the reviewing officer, the commanding officer of the troops turns out of the column, takes post on the right of the reviewing officer, and returns saber; the members of his staff accompanying him take post on the right of the reviewing officer's staff and return saber. When the rear element of his command has passed, without changing his position, the commanding officer of the troops salutes the reviewing officer; he and the members of his staff accompanying him then draw saber and rejoin his command. The commanding officer of the troops and the members of his staff are the only ones who turn out of the column. (_C.I.D.R., No. 10._) 715. If the person reviewing the command is not mounted, the commanding officer and his staff on turning out of the column after passing the reviewing officer dismount preparatory to taking post. In such case, the salute of the commanding officer, prior to rejoining his command, is made with the hand before remounting. 716. When the rank of the reviewing officer entitles him to the honor, each regimental color salutes at the command _present arms_, given or repeated by the major of the battalion with which it is posted; and again in passing in review. 717. The band of an organization plays while the reviewing officer is passing in front of and in rear of the organization. Each band, immediately after passing the reviewing officer, turns out of the column, takes post in front of and facing him, continues to play until its regiment has passed, then ceases playing and follows in rear of its regiment; the band of the following regiment commences to play as soon as the preceding band has ceased. While marching in review but one band in each brigade plays at a time, and but one band at a time when within 100 paces of the reviewing officer. 718. If the rank of the reviewing officer entitles him to the honor, the band plays the prescribed _national air_ or the field music sounds _to the color_, _march_, _flourishes_, or _ruffles_ when arms are presented. When passing in review at the moment the regimental color salutes, the musicians halted in front of the reviewing officer, sound _to the color_, _march_, _flourishes_, or _ruffles_. (_C.I.D.R., No. 6._) 719. The formation for review may be modified to suit the ground, and the _present arms_ and the ride around the line by the reviewing officer may be dispensed with. 720. If the post of the reviewing officer is on the left of the column, the troops march in review with the guide left; the commanding officer and his staff turn out of the column to the left, taking post as prescribed above, but to the left of the reviewing officer; in saluting, the captains give the command: 1. _Eyes_, 2. _LEFT_. 721. Except in the review of a single battalion, the troops pass in review in quick time only.
