Order - in the Ranks
Order in the ranks is the appropriate spacing in ranks for soldiers when assembling or receiving instruction from their superiors. It also is good for maneuvering and may be used in the march. Soldiers are sufficiently separated to go through the motions with their weapons without undue risk to one another.
The space for Order in the ranks is easy to determine. Should two soldiers in a rank rest their hands on their hips to have their elbows crooked (akimbo), the elbows of the two should almost touch. Granted it's easier to poise the left arm rather than the right, which must hold the weapon, but even with only one arm akimbo, simply visualize double the distance from the elbow to the person at the left.
Colonel Barriffe provides commands for going to Order in the ranks and which depend on the initial status of the ranks:
(Remember, a rank is 90 degrees to a file and consists of one soldier from each of several files.)
