=363.= The troopers and their mounts must be so trained as to enable alignment and interval to be kept with sufficient accuracy to maintain cohesion in the mounted charge and to, present a creditable appearance at ceremonies and at other occasions of a formal or ceremonial character. A disproportionate amount of time and energy will not be devoted to this detail. =364.= The use of dressing _by command_ is ordinarily confined to elementary instruction (as preparation for the march in line) and to formations of a distinctly ceremonial character. At all other times the troopers are required habitually to align themselves on the base trooper without special command and to look to the front as soon as aligned. Formal dressing is employed only when the squad is at a halt. =365.= The caution: =DRESS=, may, if necessary, be given to the squad when marching (par. 367); but it will not be employed when it is practicable to use instead cautions addressed by name to the individual trooper or troopers who are at fault. =366.= Alignments, dismounted, are executed by the same general methods as when mounted. At the command: =DRESS=, the hand is placed upon the hip to verify the interval (par. 57). Each trooper in dressing so places himself that his right arm rests lightly against the arm of the man on his right and that his eyes and shoulders are in line with those of the man on his right. The left hand is dropped to the side at the command =FRONT=. LEADING THE SQUAD. (_See also_ pars. 322-332.) =367.= The squad being in line at a halt, the instructor directs the guide (par. 371) to maintain a position at a distance of 3 yards (about one horse length) in rear of him and to follow accurately in his path, whether such path be a straight line or a curve. He explains to the other troopers that in marching they are so to regulate on the guide as to preserve as nearly as practicable their alignment and interval in the rank, individually increasing and decreasing the gait or pace (Def.) as may be necessary to do this. All are cautioned that they must learn to keep their proper positions in the rank without unnecessary rigidity without making sudden changes in gait or pace and without keeping their eyes constantly fixed on the guide. They are instructed that while riding with the head and eyes habitually directed as in par. 198 they will keep an alert lookout over the ground in front, cast frequent glances toward the leader so as to observe the latter's movements, and glance occasionally toward the guide to assure that the alignment is being correctly maintained. Having given these instructions, the leader places himself, facing to the front, 3 yards in front of the guide, commands: =FOLLOW ME=, and moves forward. The leader must be, careful to march steadily, so regulating his direction and gait at first as to enable the guide to conform without difficulty.
