There are in dressing a number of common errors that we should try to avoid. Don't jab the man on your left with your elbow. If you are not on the line, move your feet. Don't lean forward or backward. Be sure to touch gently the man on your right with your right arm. Be certain to keep your left elbow forced well to the front. This is a little uncomfortable at first, but unless we do this our arms will not measure the 4 inches correctly. Don't hump up the left shoulder, and don't turn the shoulders to the right. Keep fingers of left hand extended and joined. We want to place especial stress on the importance of three movements in the school of the squad. When you have thoroughly mastered these three, you will have a splendid basis for the remainder of the School of the Squad, the full value of which you will later appreciate. These are: Squad right, Squad right about, and Right turn. The first line drawing in this chapter shows correct proportions of interval and distance. To save space and for convenience, the drawings hereafter are made without regard to proportions (intervals and distances). First Movement SQUAD RIGHT Being in line, to turn and march: 1. Squad right (left), 2. MARCH. In this movement many instructors have recruit squads step off on the 7th count. When the drill progresses the squad should step off on the 5th count. [Illustration: This is what we have This is what we want] At the command march, No. 1 in the front rank faces to the right in marching and marks time; Nos. 2, 3, and 4 of the front rank turn 45 degrees to the right (right oblique), place themselves abreast (on the same line) of No. 1 and mark time. Now it is difficult quickly to understand the movements of the rear rank. Give them a lot of study and don't go on until you are certain that you understand. [Illustration: This is the way it is done.] No. 3 moves straight to the front. No. 2 follows No. 3. No. 1 follows No. 2. When they (Nos. 3, 2 and 1) arrive in rear of their file leaders, (Nos. 3, 2 and 1, front rank) they face to the right in marching and mark time. No. 4 of the rear rank moves straight to the front four paces, and places himself abreast of No. 3, rear rank. When No. 4, front rank, and No. 4, rear rank, are on the line, (and the remainder of the squad must glance toward them to see when that is true), the whole squad moves forward without further command. Note that we have said that No. 1 front rank marks time. We see that he becomes, temporarily, an immovable pivot for his squad. We, therefore, call him a fixed pivot. Had the command been squad left, instead of squad right, No. 4 would have been the fixed pivot instead of No. 1. Being in line, to turn and halt: 1. Squad right (left), 2. MARCH, 3. Squad, 4. HALT. The turn is executed as prescribed in the preceding case except that all men, on arriving on the new line, mark time until the command halt is given, when all halt.
