[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.
[722.] In reviews of brigades or larger commands, each battalion, after the rear has passed the reviewing officer 50 paces, takes the double time for 100 yards in order not to interfere with the march of the column in rear; if necessary, it then turns out of the column and returns to camp by the most practicable route; the leading battalion of each regiment is followed by the other units of the regiment.
[723.] In a brigade or larger review a regimental commander may cause his regiment to stand at ease, rest, or stack arms and fall out and resume attention, so as not to interfere with the ceremony.
[724.] When an organization is to be reviewed before an inspector junior in rank to the commanding officer, the commanding officer receives the review and is accompanied by the inspector, who takes post on his left.
Battalion Review.
[725.] The battalion having been formed in line, the major faces to the front; the reviewing officer moves a few paces toward the major and halts; the major turns about and commands: 1. Present, 2. ARMS, and again turns about and salutes.
The reviewing officer returns the salute; the major turns about, brings the battalion to order arms, and again turns to the front.
