Riot-control projectiles are designed to harass enemy personnel by emitting CS irritant fumes. An example of a
155-millimeter riot-control projectile is shown in Figure 2-40. The XM631 is a base-ejection, burning-type, tactical
CS projectile. It has a steel body with a pressed-in and pinned base plug and an eyebolt lifting plug. It uses an
MTSQ fuze. Its color code is a gray body with two red bands and red markings. The DODIC for the XM631 is

Illuminating projectiles are designed to illuminate the battlefield at night or during periods of reduced visibility. An
example of an illuminating projectile is shown in Figure 2-40. M485-series projectiles have a forged-steel body
with a pinned base plug and an eyebolt lifting plug. This is a base-ejection, burning-type projectile. The color
code for older projectiles of this type is an olive-drab body with white markings. Newer projectiles have an olive-
drab body with one white band and white markings. The DODIC for M485-series projectiles is D505.
Cannon-launched guided projectiles are designed for use against tanks, armored vehicles, and other hardened
targets. The M712 Copperhead (shown in Figure 2-41) is a cannon-launched, HEAT, guided projectile. It is
designed for the use with the M109A1/A2/A3, the
