ment and interval on the guide. The rate of march of the 

 leader and the guide should not be so rapid as to make it 

 impracticable for the troopers on the marching flank of the 

 squad to preserve their alignment on the guide during the turn. 

 The guide moves in tlie trace of the Jeader during the turn, as 

 well as before and after the turn. When the turn Is executed 

 by the marching squad the leader gives the command after he 

 has begun to change direction and at the moment when the 

 guide arrives at the point tchere the leader straightened his 

 horse in the new direction (par. 471). AVhen executed from a 

 halt the second command can not be given as above indicated. 

 The leader in that case begins to turn at the command of exe- 

 cution, while the guide, instead of beginning the actual turn 

 at once, moves forvrard so as to move, during the turn, in the 

 trace of the leader (par. 367). 



In executing the turn dismounted the leader so regulates 

 the length of step of the guide that the trooper on the march- 

 ing flank can keep the regular step corresponding to the gait 

 at which the turn is made. The other troopers lengthen or 

 shorten the step accordingly, maintaining the cadence and 

 their alignment and interval with respect to the guide. If the 

 turn be terminated by the commands : 3. Forward, 4. MARCH, 

 all the troopers resume the regular step at the fourth com- 

 mand . 



387. In executing the turn in a squad or platoon, the leader, 

 followed by the guide, so turns on the arc of a circle that the 

 pivot trooper, in conforming to the guide's movements, marches 

 on (he arc of a circle whose radius varies with the gait of the 

 guide, this radius being 2 yards at a walk, 4 yards at a trot, 

 and G yards at a gallop. When the turn is executed dis- 

 mounted the corresponding radius, in either quick or double 

 tiu)e. is 1 yard. 



388. At the command: 1. Right (left) half turn, 2. MARCH; 

 ^. Forward, 4. MARCH; or 3. Squad, 4. HALT, a change of di- 

 rection of 45° may be made in accordance with the principles 

 explained in pars. S86 and 387. The arm signal for the half 

 turn follows the rule indicated for the full turn (par. 386). 



389. In all movements in these regulations in the course of 

 which fours, twos, or troopers execute a turn or half turn this 

 last movement is made by each element in accordance wuth the
