The majors and the commanders of the machine-gun company and mounted scouts (or detachment) each, when his command is in place, salutes the adjutant and commands: At ease; the adjutant returns the salutes. When all have saluted and the band is in place, the adjutant rides to the colonel, reports: Sir, the regiment is formed, and takes his post. The colonel draws saber.
The formation in column of squads may be modified to the extent demanded by circumstances. Prior to the formation the adjutant indicates the point where the head of the column is to rest and the direction in which it is to face: he then posts himself so as best to observe the formation. At [adjutant's call] or assemble the leading battalion marches to, and halts at, the indicated point. The other battalions take positions from which they may conveniently follow in their proper places.
[335.] For ceremonies, or when directed, the regiment is formed in line or line of masses.
The adjutant posts himself so as to be 6 paces to the right of the right or leading company of the right battalion when the regiment is formed and faces in the direction in which the line is to extend. [Adjutant's call] is sounded; the band plays.
The adjutant indicates to the adjutant of the right battalion the point of rest and the direction in which the line is to extend, and then takes post facing the regiment midway between the post of the colonel and the center of the regiment. Each of the other battalion adjutants precedes his battalion to the line and marks its point of rest.
The battalions, arriving from the rear, each in line or close column, as the case may be, are halted on the line successively from right to left in their proper order and places. Upon halting, each major commands: 1. Right, 2. DRESS. The battalion adjutant assists in aligning the battalion and then takes his post.
The band, arriving from the rear, takes its place in line when the right battalion has halted; it ceases playing when the left battalion has halted. The machine-gun company and the mounted scouts (or detachment) take their places in line after the center battalion has halted.
The colonel and those who accompany him take post.
When all parts of the line have been dressed, and officers and all others have reached their posts, the adjutant commands: 1. Present, 2. ARMS. He then turns about and reports to the colonel: Sir, the regiment is formed; the colonel directs the adjutant: Take your post, Sir, draws saber and brings the regiment to the order. The adjutant takes his post, passing to the right of the colonel.
