Left Flank March Procedures
The squad may be marched to the flank (for short distances only) when marching in column. The command for this movement is Right (Left) Flank, MARCH. The preparatory command is given as the foot in the desired direction strikes the marching surface, and the command of execution is given the next time the foot in the desired direction strikes the marching surface.
On the command of execution MARCH, all members take one more step, pivot 90 degrees in the commanded direction on the ball of the lead foot, and step off in the new direction with the trailing foot.
As the members begin to march in the new direction, they glance out of the corner of the right eye and dress to the right
