Open Order - in the Ranks
Open Order in the ranks is double the spacing for Order between soldiers in the ranks. It is particularly useful for making sufficient room for doubling ranks.
The space for
Open Order in the ranks is simply double the length of the left arm
with fingers extended from one person to his comrade at his left.
Note: the only difference between these commands and the ones for Order is the addition of one word in each: "Open." All soldiers should listen closely to their superiors in order to catch this little addition.
(Remember, a rank is 90 degrees to a file and consists of one soldier from each of several files.)
