France. The distance between companies is 10 paces (7.5 m.). The depth of each rank is reckoned at 1.40 m. on the march (in Germany 1.10 m.), and that of every 100 men at 50 m. Depth of a battalion, including combat train, on the march is 450 m.
Russia. The distance between companies is 10 paces (7.1 m.). The battalion without combat train has a depth of 350 paces (249 m.). The combat train follows in rear of the regiment.
A German regiment of four battalions with combat train has a depth of 1,650 m. on the march; a Russian regiment, a depth of 1,725 paces (@ 71 cm.)=1,215 m. (elongation on the march not considered).
Italy. The distance between companies is 10 paces (7.5 m.). The battalion has a depth of 422 m. on the march.
8. THE REGIMENT AND THE BRIGADE.
For a discussion of the importance of the regiment and of the brigade see page 37 supra. All movements must be executed in an orderly manner by regiment and brigade, in any formation, without breaking up tactical units, and the entity of the whole body must be preserved at the same time by a skillful use of the terrain. If necessary, a base battalion may be designated.
When regiments or brigades are assembled, the formation, disposition, intervals and distances of the tactical units depend upon the terrain and the intentions of the commander. Frequently the tactical units (battalions and regiments) are assembled in separate groups.
When considerations of the enemy and the terrain do not dictate otherwise, the battalions, each, as a rule, in deep column, are posted in one or more lines, at 30-pace intervals and distances, rear battalions covering those in front or the gaps between them. An appropriate formation will frequently be that in which route columns are placed abreast and on the same line.
In the brigade, when assembled or deployed, the regiments may be placed abreast of each other, on the same line, or in rear of each other, i.e., in line or in echelon. When
