SECTION 20.  FORMAL GUARD MOUNTING FOR INFANTRY.

349.  Formal guard mounting will ordinarily be held only in posts or camps where a band is present.

350.  At the assembly, the men designated for the guard fall in on their company parade grounds as prescribed in paragraph 106, I. D. R. The first sergeant then verifies the detail, inspects it, replaces any man unfit to go on guard, turns the detail over to the senior noncommissioned officer, and retires.  The band takes its place on the parade ground so that the left of its front rank shall be 12 paces to the right of the front rank of the guard when the latter is formed.

351.  At adjutant’s call, the adjutant, dismounted and the sergeant major on his left, marches to the parade ground.  The adjutant halts and takes post so as to be 12 paces in front of and facing the center of the guard when formed; the sergeant major continues on, moves by the left flank and takes post facing to the left, 12 paces to the left of the front rank of the hand; the band plays in quick or double time; the details are marched to the parade ground by the senior noncommissioned officers; the detail that arrives first is marched to the line so that, upon halting, the breast of the front rank men shall be near to and opposite the left arm of the sergeant major; the commander of the detail halts his detail, places himself in front of and facing the sergeant major, at a distance equal to or a little greater than the front of his detail, and commands:  1. Right, 2.  DRESS.  The detail dresses up to the line of the sergeant major and its commander, the right front rank man placing his breast against the left arm of the sergeant major; the noncommissioned officers take post two paces in rear of the rear rank of the detail.  The detail aligned, the commander of the detail commands:  FRONT, salutes, and then reports; “The detail is correct,” or “(So many) sergeants, corporals, or privates are absent”; the sergeant major returns the salute with the right hand after the report is made.  The commander then passes by the right of the guard and takes post in the line of noncommissioned officers in rear of the right file of his detail.

Should there be more than one detail, it is formed in like manner on the left of the one preceding.  The privates, noncommissioned officers, and commander of each detail dress on those of the preceding details in the same rank or line.  Each detail commander closes the rear rank to the right and fills blank files as far as practicable with the men from his front rank.

Should the guard from a company not include a noncommissioned officer, one will be detailed to perform the duties of commander of the detail.  In this case the commander of the detail, after reporting to the sergeant major, passes around the right flank between the guard and the band and retires.
