Section II. DEMOLITION TO PREVENT ENEMY USE
98. Authority for Destruction
When capture or abandonment of the filter unit to
the enemy is imminent, the responsible unit commander
makes the decision to destroy the equipment or to render
it inoperative. Based on this decision, orders are issued
which cover the desired extent of demolition. Whatever
method of destruction is employed, it is essential that the
same parts and corresponding repair parts for all filter
units are destroyed.
99. Preferred Demolition Methods
Explosives and mechanical means, either alone or
in combination, are the most effective methods to
employ. Listed below are the vital parts in order of
priority of demolition for each preferred method. In each
case, completion of the first two steps will render the unit
inoperative. Completion of the additional steps will
further destroy the unit.
