or spiral wrap, and it has a percussion primer and an adjustable propelling charge. The color code for the M444
cartridge is an olive-drab projectile with one band of yellow diamonds and yellow markings. Its DODIC is C462.
The 105-millimeter chemical rounds are semi-fixed munitions that use adjustable propelling charges. Examples
of cartridges of this type are shown in Figure 2-33. They are used for screening, for signaling, and for spotting.
They may be either bursting-type or base-ejection, burning-type.
M60-series rounds are bursting-type WP smoke munitions. They have the additional feature of providing limited
incendiary effects. The projectile has a cylindrical forged-steel body with a streamlined ogive and a boattail base.
The base has a cover welded onto it to prevent hot gases from entering the body cavity. The cartridge case is
either drawn steel or spiral wrap, and it has a percussion primer. There are two possible color codes for this
series, depending on the vintage of the particular item. Older items have a gray projectile with yellow markings.
Newer ones have a light-green projectile with one yellow band and red markings. The DODIC for M60-series
cartridges is C454.
M84-series rounds are burning-type, base-ejection, smoke munitions. Depending on the model, the smoke may
be white (HC), red, yellow, or green. The projectile body is a forged-steel cylinder with a boattail base, a
streamlined ogive, and an MT or an MTSQ fuze. The cartridge case is either drawn steel or a three-piece steel
spiral wrap, and it has a percussion primer. The color code is a light-green body with black markings. The
DODIC for M84-series cartridges is C452.
Riot-control cartridges are intended to harass enemy personnel. They are semi-fixed munitions with base-
ejection-type projectiles. An example of a 105-millimeter riot-control cartridge is shown in Figure 2-33. The M629
round has a CS filler. The projectile has a forged-steel, cylindrical body with a streamlined ogive and a flat,
pinned-steel base plug. It is fuzed with an MT or an MTSQ fuze. The cartridge case is either brass, drawn steel,
or spiral-wrapped steel, and it has a percussion primer. The color code is a gray projectile with one red band, one
yellow band, and red markings. The DODIC for the M629 cartridge is C473.
Illuminating rounds are designed for signaling and for illuminating a designated area. They are semi-fixed
munitions, and use base-ejection-type projectiles. An example of a 105-millimeter illuminating cartridge is shown
in Figure 2-34. The M314-series projectile has a forged-steel body, a streamlined ogive, and a flat, pinned base
plug. It can be issued with either a closing plug, an MT fuze, or an MTSQ fuze. The cartridge case is either of
brass or three pieces of spiral-wrapped steel, and it has a percussion primer. The color code is a white projectile
with black markings. The DODIC for the M314 series is C449.
Large-Caliber Howitzer Cartridges. The 155-millimeter and 8-inch howitzer cartridges are all indirect-fire
rounds. They are all separate-loading, and are issued as separate items. Projectiles, propellant, primers, and
fuzes are required to assemble a complete round. Included are HE, AT, antipersonnel, and chemical (bursting
and burning-type) munitions. The paragraphs that follow address the 155-millimeter munitions and the 8-inch
155-Millimeter Cartridges. All 155-millimeter HE projectiles are designed for blast and fragmentation. They
are used primarily against personnel and against fortified positions. Examples of 155-millimeter HE projectiles
are shown in Figure 2-35. The M107 is an HE projectile that has fuze cavities of two different depths, described
as normal and deep cavities. It uses PD or time fuzes for normal-cavity, and proximity fuzes for deep-cavity. The
projectile is a steel cylinder with a long ogive and a boattail base. There is a steel base cover welded over the
base to prevent hot gases from entering the explosive cavity. This
