_a. Flame thrower._ One or more small-arms bullets through the fuel tanks will prevent any immediate use of the flame thrower. Additional rounds may be put through the pressure tank. If the pressure tank is charged, the pressure-tank valve should be opened for a few seconds, thus permitting the contents to dissipate. This is necessary if rounds are to be fired point-blank. The gun may be rendered useless by bending it over a hard object. A sledge or ax will demolish valves and tubes. A fragmentation grenade will also achieve demolition. _b. Filling and charging apparatus._ The flexible tubing, gages, and valves may be destroyed by blows with an ax, sledge, or other heavy instrument. The large pressure cylinders are rendered useless by releasing the contents and then destroying the valves by blows with an ax or sledge. Cylinders can be stacked like cordwood in groups of five and demolished by the detonation of four 1/2-pound blocks (2 pounds) of TNT in their midst. The air compressor may be destroyed by a similar procedure. _c. Fuel._ Burn. _d. Mixing apparatus._ Containers and filling lines may be rendered useless by ax or sledge blows, or by small-arms fire. _e. Thickener._ Cans of thickener should be broken open. Contents should be thrown into a fire or into a body of water. _f. Ignition cylinders._ Burn to destroy. Personnel should stay several yards from the fire because the cylinders ignite with a slight detonation. PART THREE MAINTENANCE INSTRUCTIONS Section XI GENERAL 47. SCOPE.
