AMMUNITION

5-1. General

The ammunition for the Rifles, 5.56-MM,
Ml6 and M16Al is classified as small-arms
ammunition and is issued in the form of a
complete round. A complete round (cartridge)
consists of all the components necessary to
fire the weapon once, that is, projectile (bullet), cartridge case, propellant, and primer.

*In the past the tip has been clear or black, but currently it is
white.

a. Cartridges for the Rifles, 5.56-MM, Ml6
and M16Al are classified as centerfire cartridges. In a centerfire cartridge the primer is
located in a small well or pocket in the center
of the cartridge case head.
b. The cartridges for these weapons are
classified and identified according to type and
model as follows:
(1) Ball, M 193
(2) Tracer, Ml96
(3) Dummy, Ml99
(4) Blank, M200
5-3. Identification
a. General. Ammunition for this weapon is
identified completely by packing and marking,
including the ammunition lot number, on
original packing containers. When ammunition
is removed from its original packing container,
the full identity of the ammunition, including
the lot number, nomenclature and model designation shall be maintained with the ammunition.
b. Identification. The various cartridges can
be visually identified as itemized in table 5-l.

L- 2.2601
WE 19844

Figure 5-l. Cartridge, 5.56-MM, Ball, Ml%?.

C. Marking. Ammunition for 5.56-mm weapons has the manufacturer’s identification and
year of manufacture impressed on the head of
the cartridge case. The year is denoted by the
last two digits of the calendar year.
5-4. Care, Handling and Preservation

a. This ammunition is not dangerous to
handle. It is packed to withstand conditions
normally encountered in the field. Moisture resistant ammunition boxes are used to provide
protection during shipment and storage; however, care must be taken to prevent this packing from becoming damaged. All damaged
packing must be repaired or replaced immediately with careful attention given to the transfer of all markings to the new parts.

b. Ammunition boxes should be opened carefully as they are to be used as long as they
are serviceable.
c. Ammunition boxes should not be opened
until the ammunition is required for use. Ammunition removed from airtight containers
for extended periods of time, particularly in
damp climate, is apt to corrode, thereby rendering the ammunition unserviceable.
d. Cartridges should be protected from high
temperatures and prolonged exposure to the
direct rays of the sun. Such exposure is likely
to affect ballistic performance of the cartridges. The combination of high temperatures and a humid atmosphere is particularly
detrimental to the stability of the propellant
and to the tracer mixture in tracer ammunition.
e. Cartridges should be kept clean and free
of foreign matter. If cartridges get wet or dirty,
they should be wiped off at once. If light corrosion forms on cartridges, it should be wiped
off with a clean dry cloth. If a cartridge case
becomes so corroded that any amount of metal
is eaten away, it is dangerous to fire and should
not be fired. Cartridges should not be polished
to make them look better or brighter.
f. The use of oil or grease on cartridges is
prohibited. Oil or grease might cause injurious
abrasives to collect in weapons or produce excessive and hazardous chamber pressures
when fired.
g. Whenever practicable, ammunition should
be stored under cover. This applied particularly to tracer ammunition.
h. When it is necessary to store ammunition
in open storage, raise it on dunnage at least
six inches from the ground and cover it with
a double thickness of paulin, leaving enough
space for the free circulation of air through
the stack. Suitable trenches should be dug to
prevent water from running under the stack.
i. When ammunition is stored, it should be
segregated by caliber or millimeter, type, and
ammunition lot.

j. When only a part of a box of ammunition
is issued or used the ammunition remaining
in the ammunition box should b.e protected by
firmly fastening the cover.
k. Ammunition removed from the original
packing should be tagged or marked so as to
preserve the ammunition lot number.
1. For additional instructions in the care,
handling, and preservation, destruction of
ammunition refer to TM 9-1300-206.
5-5. Authorized Cartridges

The following cartridges are authorized for
use with this weapon:
a. Ball, Ml93
b. Tracer, Ml96
c. Dummy, Ml99
d. Blank, M200
54. Preparation for Firing

a. After removal, from packing materials,
these cartridges are ready to be used.
b. Cartridges which are not used will be
returned to their original packings. (Such cartridges will be used first in subsequent firings
so as to reduce stocks of opened packings.) If
the original packings are not utilized, the
boxes in which the ammunition is stored
should be appropriately marked with the nomenclature of the cartridges and the ammunition lot number.
5-7. Packing

The ammunition box and method of pack for
5.56-mm ammunition for these weapons is
given in drawings, specifications, or as specified in the procurement contract. The ammunition box presently being used has been
designed to withstand all conditions commonly encountered in handling, storing, and transportation of the ammunition.

CHAPTER 6
DEMOLITION OF MATERIEL TO PREVENT ENEMY USE

6-l. General

a. Rifles, subject to capture or abandonment
in the combat zone, will be destroyed only by
the authority of the unit commander, in accordance with orders of, or policy established
by the army commander. The destruction of
equipment is to be reported through regular
Command channels.
b. The information which follows is for guidance only. Certain of the procedures outlined
require use of explosives and inc:endiary grenades, normally not authorized items of issue
to the using organization. Issue of these and
related items, and conditions under which destruction will be effected are command decisions based on the tactical situation. Of the
several means of destruction, the following
generally apply :
Mechanical
Requires axe, pick mattock,
sledge, c r o w b a r , o r other
flammables or welding or
cutting torch.
Burning
Requires gasoline, oil, incendiary grenades, and other flammables or welding or cutting
torch.
Requires suitable explosives or
Demolition
ammunition.
Gunfire
Includes artillery, machine gun,
rifle grenades, and launchers
using antitank rockets. Under
some circumstances, hand
grenades may be used.
Requires burying in the ground,
Disposal
dumping in streams or marshes, or scattering so widely as
to preclude recovery of essential parts.
Destruction of essential ‘parts by mechanical
means will render the rifle useless, however,
36

selection depends upon utilizing facilities on
hand under existing conditions. Time is usually critical.
c. If destruction to prevent enemy use is
resorted to, the rifle and bipod must be damaged so that they cannot be restored to a
usable condition in combat zone either by repair or cannibalization. Adequate destruction
requires that all parts essential to the operation of the rifle and bipod be destroyed or
damaged beyond repair. However, when lack
of time and personnel prevent destruction of
all parts, priority is given to destruction of
parts in the following order:
(1) Bolt carrier group
(2) Upper receiver group
(3) Lower receiver group
It is equally important that the same essential
parts be destroyed on all like materiel, including spare parts, so that the enemy cannot
construct one, complete unit from several damaged units.
d. If destruction is directed, due consideration should be given observance of appropriate safety precautions.
6-2. Destruction of the Rifles, 5.56-MM,
M16, M16A1, Bipod, Rifle, M3

Warning: Do not use any type of mechanical
means for destruction of ammunition.
a. Method No. 1-Bg Mechanical Means.
Using an axe, pick mattock, sledge, or other
heavy implement, destroy the rifles by smashing the receiver groups, front and rear sights,
trigger and trigger guard, magazine, stock,
and controls. Also bend the barrel and cut the
sling into several pieces. Destroy the bipod
using same items listed above.
Elapsed time: about 3 minutes.

b. Method No. 2-By Burning.
(1) Place the rifle on a suitable pile of
combustible material. Pour gasoline or oil over
the rifle and bipod and the combustible material. Ignite and take cover. A hot fire is required to render the rifle and biped useless.
Elapsed time: about 3 minutes.
Warning: When igniting gasoline, due consideration should be given to the highly flam-

mable nature of gasoline and its vapor. Carelessness in its use may result in painful burns.
(2) If a welding or cutting torch is
available, burn through the barrel and receiver
groups. Destroy the stock and sling as described in paragraph a, above.
c. Method No. S-By Disposal. Bury the
rifle in a suitable hole or dump it into a
stream.
Elapsed time: about 3 minutes.

an asterisk in the allowance column.
(2) The quantitative allowances for organizational level of maintenance represents

one initial prescribed load for a 15-day period,
for the number of equipments supported. Units
and organizations authorized additional prescribed loads will multiply the number of
prescribed loads authorized by the quantity of
repair parts reflected in the appropriate
density column to obtain the total quantity of
repair parts authorized.
(3) Organizational units providing maintenance for more than 100 of these equipments
shall determine the total quantity of parts required by converting the equipment quantity
to a decimal factor by placing a decimal point
before the next to last digit of the number to
indicate hundredths, and multiplying the decimal factor by the parts quantity authorized in
the 51-100 allowance column. Example,
authorized allowance for 51-100 equipments is
12; for 140 equipments multiply 12 by 1.40 or
16.80 rounded off to 17 parts required.
(4) Subsequent changes to allowances will
be limited as follows: No change in the
range of items is authorized. If additional
items are considered necessary, recommendations should be forwarded to Commanding
General, Headquarters, U.S. Army Weapons
Command, ATTN : AMSWE-SMM-SA, Rock
Island, Ill 61201, for exception or revision to the allowance list. Revisions to the
