3. On the march.—A squad marching in line, or by the diagonal march, will be taught to form fours precisely as when forming from the halt; the right files marking time two paces whilst the left files are moving to their places. Should the word Right or Left or Right or Left Incline follow, the squad will turn in the direction ordered.
4. When in file.—Fours will be formed by the left files, moving forward or back into their position in Fours, right files if on the move marking time two paces.
5. When moving in fours, the squad may be turned in any direction, diagonal or otherwise.
6. When moving in fours, the squad may be ordered to form two-deep; on the command, Form—Two-deep, the left files will step up or fall back into their places in two-deep formation, the right files marking time two paces.
7. When from line a squad is turned to the right or left in fours, if to the right the left will direct, and if to the left the right will direct without any further word of command, and each section of fours will dress by that flank.
8. A squad moving to a flank in fours by the diagonal march, will form two-deep on being turned into line.
41. Fours changing direction, and forming squad.
1. Changing direction.—A squad moving in fours, will change direction to the right, in the same manner as in file: each four wheeling successively round the same point as described in S. 31.
If the squad be ordered to halt, or mark time, when a part of the fours only have wheeled, the remainder will be instructed to cover off, if required, by the diagonal march, on the command Rear fours—Cover.
2. Forming squad.—When a squad moving in fours is ordered to form squad either on the right or left, it will re-form two-deep, and then proceed as in S. 32, the men taking up their proper places as they come up to the alignment.
