A squad is a group of 8-12 individuals formed for instruction, discipline, control, and order. The squad drills as a unit and executes movements together. The squad is normally formed in a single rank with the squad leader in the lead position maintaining 3 paces from the squad. Squads can be sized according to height and armed squads fall in at Order Arms. Counting off allows individuals to be numbered in line or column. Close and Extend commands are used to adjust the interval between squad members. Oblique marching can be used to change the direction of march.
