120. Method No. 1 Destruction by Demolition
a. Planning for simultaneous detonation, prepare five 2-pound
charges  of  EXPLOSIVE,  TNT  (two  l-pound  blocks  or  equiva-
lent  per  charge  together  with  the  necessary  detonating  cora
Place the charges as follows:
to make up each charge).
(1) Set the first c h a r g e
on
t h e left front a x l e
and
trun-
nion  assembly.
(2) Set the s e c o n d charge on the right front axle and trun-
nion assembly.
(3) Set the third charge
on
t h e left rear a x l e
and
trun-
nion assembly.
(4) Set the fourth charge on the right rear axle and trun-
nion assembly.

c. Provide  for
dual
priming
to
minimize
the
possibility
of
a misfire. For priming, either a nonelectric blasting cap crimped
to at least 5 feet of safety fuse (safety fuse burns at the rate
of 1 foot in approximately 4 seconds; test before using) or an

must be protected from moisture at all times.  The safety fuse

or

fuse separated from the charges until required for use.
Note. For the successful execution of methods of destruction involving the
use of demolition materials, all personnel concerned will be thoroughly fa-
miliar with the pertinent provisions of FM 5-25. Training and careful
planning are essential.
d. Destroy  the  tires  by  placing  an  incendiary  grenade  under
each  tire.  Fire  the  grenades.  The  detonation  of  the  explosive
charges
should
be
delayed
until
the
incendiary
fires
are
well
started.
This
will
prevent
the
fires
from
being
extinguished
by
the
blast
when
the
charges
are
detonated.
