als for specific items of equipment. The exact methods used will depend upon the means available.
(2) MACHINE GUNS, MORTARS, INDIVID- UAL WEAPONS, AND AMMUNITION. (a) The firing pin points of all small arms, except the re- volver, can be broken by inserting the points into the holes in the face of the bolt and bending. Bar- rels of the M1, M1903, and M1917 rifles, the Brown- ing automatic rifles, and carbines, can be bent by grasping the butt with both hands and swinging the barrel against a tree, rock, or firm ground.
(b) The barrels of caliber .45 submachine guns and of caliber .30 and caliber .50 machine guns can- not be easily bent under field conditions. Parts es- sential to the operation of the guns should be re- moved and destroyed. The same essential parts must be destroyed on all like units to prevent the enemy's constructing one complete unit from several dam- aged ones. Field strip machine guns; then, using the barrel as a sledge, destroy the cover, back plate, lock frame, and barrel extension. In the same man- ner, destroy machine gun mounts.
(c) Mortar tubes may be destroyed by using a mortar round or incendiary grenades. If evacuation is possible, carry the sights; if evacuation is not possible, thoroughly smash them.
(d) Ammunition may be destroyed by burning. Large caliber ammunition (37-mm or larger) can be destroyed by sympathetic detonation, using TNT.
(e) Fire control equipment is difficult to replace. It should be the last equipment to be destroyed.
