DEMOLITION OF THE PUMPING UNIT TO PREVENT ENEMY USE
When capture or abandonment of the pumping
unit to an enemy is imminent, the responsible unit
commander must make the decision either to destroy
the equipment or to render it inoperative. Based on this
decision, orders are issued which cover the desired
extent of destruction. Whatever method of demolition is
employed, it is essential to destroy the same vital parts
of all pumping units and all corresponding repair parts.
63. Demolition To Render Pumping Unit Inoperative
a. Mechanical Means. Use sledge hammers,
crowbars, picks, axes, or other heavy tools which may
be available to destroy the following:
(1) Engine crankcase and manifolds.
(2) Carburetor, magneto, and governor.
(3) Shroud, starter, and generator.
The above steps are minimum
requirements for this method.
(4) Pump chamber.
(5) All controls and instruments.
b. Misuse. Drain the engine crankcase. Pour
sand, gravel, bolts, screws, or broken glass into the fuel
tank, oil filler pipe, and pump priming hole.
64. Demolition by Explosives or Weapons Fire
a. Explosives. Place as many of the following
charges (fig. 82) as the situation permits and detonate t
them simultaneously with detonating cord and a suitable
b. Weapons Fire. Fire on the pumping unit with
the heaviest practical weapons available.
65. Other Demolition Methods
a. Scattering and Concealment. Remove all
easily accessible parts such as the carburetor, fuel
pump, magneto, generator, and starter and scatter them
through dense foliage, bury them in dirt, or sand, or
throw them in a lake, stream, or other body of water.
b. Burning. Pack rags, clothing, or canvas under
and around the unit. Saturate this packing with
gasoline, oil, or diesel fuel and ignite.
c. Submersion. Totally submerge the unit in a
body of water to provide water damage concealment. A
body of salt water will do greater damage to metal parts
than submersion in a body of fresh water.
All operators should receive thorough training in
the destruction of the pumping unit. Refer to TM 5-25.
Simulated destruction, using all of the methods listed
above, should be included in the operator training
program. It must be emphasized in training, that
demolition operations are usually necessitated by critical
destruction is limited. For this reason, it is necessary
that operators be thoroughly familiar with a:! methods of
destruction of equipment, and be able to carry out
demolition instructions without reference to this or any
