Note that the leading corporal turns his squad well to the right rear and then to the left.
We have assumed the company to be at a halt; suppose it is moving forward. In that case the base squad simply continues moving forward after it has deployed until the captain gives the command halt. The other corporals conduct their squads by the shortest routes to their proper places and deploy them on the general line.
When the company, while moving, is deployed, it is a common error for squads in rear of the base squad to take long and fast steps and come up on the line of the base squad. This should not be done unless the command double time is given. In which case all the squads take up the double time, except the base squad.

RULES FOR DEPLOYMENTS
The command guide right (left or center) indicates the base squad for the deployment; if in line it designates the actual right (left or center) squad; if in column the command guide right (left) designates the leading squad, and the command guide center designates the center squad. After the deployment is completed, the guide is always center without command, unless otherwise ordered.
At the preparatory command for forming skirmish line, from either column of squads or line, each squad leader (except the leader of the base squad, when his squad does not advance) cautions his squad, follow me or by the right (left) flank, as the case may be; at the command march, he steps in front of his squad and leads it to its place in line.
Having given the command for forming skirmish line, the captain, if necessary, indicates to the corporal of the base squad the point on which the squad is to march; the corporal habitually looks to the captain for such directions.
