QUALITY OF MATERIAL
Material used for replacement, repair, or modification must meet the requirements of this manual. If quality of material
requirements are not stated in this manual, the material must meet the requirements of the drawings, standards, spec-
ifications, or approved engineering change proposals applicable to the subject equipment.
DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE
Refer to TM 750--244--6 for procedures on how to destroy the M88A1.
Below are some general guidelines to follow in destruction of equipment to prevent enemy use.
Destruction of the vehicle and equipment, when subject to capture or abandonment in a combat zone, will be
undertaken only when such action is necessary in accordance with orders of, or policy established by, the Army
commander.
In general, destruction of essential parts, followed by burning, will usually be sufficient to render the vehicle and equip-
ment useless. Time is usually critical.
Materiel must be damaged so that it cannot be restored to usable condition by either repair or cannibalization. If lack
of time or personnel prevents destruction of all parts, give priority to destruction of parts hardest to replace. It is im-
portant that the same parts be destroyed on all vehicles to prevent construction of one complete vehicle from several
damaged ones.
For information and conditions under which destruction of XT--1410--4 Cross--Drive Transmission should be undertak-
en to prevent enemy use, and for other methods of destruction, refer to TM 9--2350--256--20 and TM 750--244--6.
The procedure outlined below requires the use of demolition materials and explosives, which normally may not be au-
thorized items of issue to the using organization. The issue of these and related materials and conditions under which
destruction will be effected are command decisions in each case, according to the tactical situation.
Varying degrees of damage to the armament and other equipment may be expected. Incidental complete destruction
of the entire vehicle requires that applicable parts of the procedures in TM 9--2350--256--20 be coordinated for the
destruction of the vehicle as listed below.
1. Remove and empty portable fire extinguishers and discharge the fixed fire extinguisher system.
2. Smash all vital elements such as auxiliary power unit, batteries, switches, instruments, hydraulic valves, cou-
pling devices, mechanical transmission, hydraulic pumps, and all accessible engine and transmission compo-
nents. Slash hydraulic lines and electrical cables and harnesses.
3. Drain the fuel and hydraulic oil tanks or puncture them as near the bottom as possible.
4. For the engine compartment, transmission, tracks, winches and boom, prepare eleven 2--pound demolition
charges, using 1--pound TNT blocks or equivalent together with the necessary detonating cord to make up the
required charges. Place the charges as follows:
•
Set the first charge on the accessory drive housing at the forward end of the engine.
•
Set the second and third charges on the engine, one on the left side and one on the right side.
•
Set the fourth charge between the engine and the transmission.
•
Set the fifth and sixth charges on the track driving sprockets, one on the left side and one on the right
side.
•
Set the seventh charge on the main winch gear case.
•
Set the eighth and ninth charges on the base of the hoisting boom at the boom crank arms, one on the
left side and one on the right side.
•
Set the tenth and eleventh charges on the hoisting boom stayline crankarms, one on the left side and one
on the right side.
•
Connect all eleven charges for simultaneous detonation with detonating cord.
5. Provide for dual priming to minimize the possibility of a misfire. For complete details on the use of demolition ma-
terials and methods of priming and detonating demolition charges, refer to FM 5--250. Training and careful plan-
ning are essential. The danger area is estimated to be 500 yards; elapsed time is approximately 10 minutes.
