100 MAFTJAL FOR NONCOMMISSIONED OFFICERS. 



This whistle signal may be used as a preliminary to cease 

 firing. 



TO CEASE FIRING. 



189. CEASE FIRING. 



Firing stops ; rifles not already there are brought to the 

 position of load, the cut-off turned down if firing from maga- 

 zine, the cartridge is drawn or the empty shell is ejected, the 

 trigger is pulled, sights are laid down, and the rifle is brought 

 to the order. 



Cease firing is used for long pauses to prepare for changes 

 of position or to steady the men. 



140. Commands for suspending or ceasing fire may be given 

 at any time after the preparatoi^y command for firing whether 

 the firing has actually commenced or not. 



TARGET DESIGNATION. 



141. In the training of men in the mechanism of the firing 

 liMe, they should be practiced in repeating to one another 

 target and aiming point designations and in quickly locating 

 and pointing out a designated target. They should be taught 

 to distinguish, from a prone position, distant objects, par- 

 ticularly troops, both with the naked eye and with field glasses. 



Owing to the invariable custom of attempting to conceal fire 

 trenches, it is necessary to have some ready method of indi- 

 cating the exact location of an indistinct pit or trench occupied 

 or supposed to be occupied by an enemy in order that effective 

 fire may be opened. The so-called clock system furnishes one 

 of the simplest devices for so doing. Two methods of apply- 

 ing tills system are indicated below. 



First method: That in which an imaginary clock dial is 

 assumed to be horizontal, its center at the Jiving point and the 

 center-XII line of the dial perpendicular to the front of the 

 firing line. 



To designate a target the commander announces, for ex- 

 ample: Target at 11 o'clock, range 800 yards, a trench. Each 

 man looks along the center-11 o'clock line of his imaginary 

 dial, estimates the distance (800 yards) along that line, and 

 thereby locates the trench.
