At this command all except the right file execute eyes right, and beginning on the right, the men in each rank count one, two, three, four--one, two, three, four; each man turns his head and eyes to the front as he counts.
The purpose of putting the left hand on the hip is to get enough elbow room. A man should have sufficient space to operate his piece. These four-inch intervals give it to him.
Note the space between elbows (interval) is 4 inches. The space between the front and rear rank (distance) is 40 inches, and is measured from the back of the man in front to the breast of the man in the rear.
ALIGNMENTS
To align the squad, the base file or files having been established: 1. Right (left), 2. DRESS, 3. FRONT.
At the command dress, all men place the left hand upon the hip (whether dressing to the right or left); each man, except the base file, when on or near the new lines executes eyes right, and, taking steps of 2 or 3 inches, places himself so that his right arm rests lightly against the elbow of the man on his right (vice versa in left dressing), and so that his eyes and shoulders are in line with those of the men on his right, and also that each man can see the eyes of at least two men on his right.
