The run, without keeping step (_Marsch! Marsch!_) is employed in rapidly crossing short, fire-swept spaces, in changing quickly from one formation to another, and in the charge. 5. MOVEMENTS OF THE COMPANY IN LINE. The commander of the center platoon is the guide. A change of direction is effected by inclining toward the new direction (at the command: “Half right, march!” when the angular change of direction is less than 45 degrees), by indicating a new point to march on, or by executing a turn. 6. THE COLUMNS OF THE COMPANY; MOVEMENTS IN COLUMN; FORMATION OF LINE. Column of Twos.[73] [73] _Reihenkolonne._ Column of twos is formed by facing in the indicated direction. Marching at attention the depth of an organization in column of twos is equal to its front when in line. The column of twos is used in marching by the flank for short distances only, as the march at attention in this formation unduly fatigues the men. In addition, this formation may be used, in exceptional cases, on narrow roads; but the column becomes considerably elongated (as much as 165%), when marching at route step. Line is formed from column of twos either by facing, or by executing front into line. Column of Squads. This is an open column formed (the company being in line at a halt or in motion) by each squad executing a turn of 90 degrees. It may also be formed from line at a halt by the squad on the designated flank moving straight to the front, the others executing a turn of 90 degrees toward the proper flank, then following the leading squad.[74] Column of squads may also be formed by executing “Squads right (left), column right (left).” Line is formed by each squad executing a turn of 90 degrees or by executing front into line (without regard to the original front). [74] “Right forward, fours right.” _Translator._ [Illustration: Column of Squads.] [Illustration: Route Column.] Route column is formed from column of squads by the squads in each section closing to facing distance, the file closers, musicians, and hospital corps men forming ranks of four men, in the gaps thus created. (Par. 91 German I. D. R.) With the exception of Russia, which employs a section column, of Switzerland, which uses a column of squads, and of France, which has adopted a wheel by fours like that of the cavalry, all other armies employ the _column of fours_[75] as their march formation. [75] _Doppelreihenkolonne_. Column of fours is, as a rule, formed as follows: The even numbered men place themselves on the right or left of the odd numbered men by making an appropriate turn, thus forming a column of fours whose length is equal to the front of the company in line. In the plate below let the Roman numerals represent front rank men, the Arabic numerals rear rank men, and the horizontal line the original front occupied; column of fours will then be formed to the right, in the different states, as shown: [Illustration: Austria.
