The third command is given immediately after the second. The turn is executed as prescribed in the preceding paragraph except that all men, on arriving on the new line, mark time until the fourth command is given, when all halt. The fourth command should be given as the last man arrives on the line. 121. Being in line, to turn about and march: 1. _Squad right (left) about_, 2. _MARCH_. At the second command, the front rank twice executes _squad right_, initiating the second _squad right_ when the man on the marching flank has arrived abreast of the rank. In the rear rank the third man from the right, followed by the second and first in column, moves straight to the front until on the prolongation of the line to be occupied by the rear rank; changes direction to the right; moves in the new direction until in rear of his front-rank man, when all face to the right in marching, mark time, and glance toward the marching flank. The fourth man marches on the left of the third to his new position; as he arrives on the line, both ranks execute _forward, march_, without command. 122. Being in line, to turn about and halt: 1. _Squad right (left) about_, 2. _MARCH_, 3. _Squad_, 4. _HALT_. The third command is given immediately after the second. The turn is executed as prescribed in the preceding paragraph except that all men, on arriving on the new line, mark time until the fourth command is given, when all halt. The fourth command should be given as the last man arrives on the line. _To Follow the Corporal._ 123. Being assembled or deployed, to march the squad without unnecessary commands, the corporal places himself in front of it and commands: _FOLLOW ME_. If in line or skirmish line, No. 2 of the front rank follows in the trace of the corporal at about 3 paces; the other men conform to the movements of No. 2, guiding on him and maintaining their relative positions. If in column; the head of the column follows the corporal. _To Deploy as Skirmishers._ 124. Being in any formation, assembled: 1. _As skirmishers_, 2. _MARCH_. The corporal places himself in front of the squad, if not already there. Moving at a run, the men place themselves abreast of the corporal at half-pace intervals, Nos. 1 and 2 on his right, Nos. 3 and 4 on his left, rear-rank men on the right of their file leaders, extra men on the left of No. 4; all then conform to the corporal's gait. When the squad is acting alone, skirmish line is similarly formed on No. 2 of the front rank, who stands fast or continues the march, as the case may be; the corporal places himself in front of the squad when advancing and in rear when halted. When deployed as skirmishers, the men march at ease, pieces at the trail unless otherwise ordered. The corporal is the guide when in the line; otherwise No. 2 front rank is the guide.
