(c) Column to the front is formed from line on the base at the gait of march (a) or at the gait ordered (e). The other elements (par. 336) take or maintain a correspondingly slower gait (or, if halted, remain so) until they can move at the gait of the base to take their places in the column. If an increased gait be commanded at any time, it is taken at first only by the leader and base or by the leader and those elements that have already moved to enter the column (f)
(d) In cases not covered by (b) or (c), if the base and other elements have equal distances to go they move at the gait of march or at that indicated in the command (e.g., 1. Platoons right turn, trot; 2. MARCH).
(e) In cases not covered by (b), (c), or (d) (e.g., assemble from foragers, par. 414), or by some special provision in the description of the corresponding movement (e.g., echelon, par. 702) the base maintains the gait of march (a) or takes that of the leader; the other elements move at a correspondingly faster or slower gait as may be necessary for the execution of the movement and on arriving at their places take the gait of the base (par. 338). If a special gait be commanded, it is taken by the base or by the other elements, in accordance with the principle stated in (f).
(f) When the commander indicates a special gait, whether in the preparatory command or during the execution of the movement, the effect is always to, hasten the completion of the movement. This principle will assist in applying the rules in (b), (c), and (e).
(g) Changes of gait made by elements, without command, in accordance with the above rules, are, except as specially indicated in the commands, changes of one degree.
338. Any exceptions to the above rules are noted where they occur.
339. Gaits for movements on foot.—(a) The general principles of gaits for mounted movements apply to movements on foot with the modifications noted in (b) to (g), below, and such others as are to be readily inferred from the application of the principles of the School of the Trooper, Dismounted.
(b) No element moves in double time unless the movement be executed when marching in double time or double time be commanded (par. 47) or otherwise indicated by the leader. No trooper increases the length of the step or the cadence unless specially so prescribed.
(c) The leader so controls the movements of the base as to facilitate the execution of the movement in accordance with (b), above. This will involve halting the base whenever certain movements (e.g., those from column into line) are executed in quick time.
(d) If double time be included in the preparatory command for a movement, the indication is obeyed in accordance with the principles of par. 337.
