M6 AND M6A1 CN-DM RIOT-CONTROL HAND GRENADES

The M6 and M6A1 grenades (Figure E-6) contain a combination mixture of CN and DM. They differ chiefly in external appearance and the manner in which the filler is combined.

a. Body. The M6 and M6A1 grenade bodies are sheet metal. The M6 has six emission holes at the top and two rows of nine emission holes each along the sides. The M6A1 has four emission holes at the top and one at the bottom.

b. Filler. The M6 grenade has 10.5 ounces of CN-DM mixture; the M6A1 has 9.5 ounces of CN-DM mixture.

c. Fuze. The fuze is an M201A1.

d. Weight. The M6 grenade weighs 17 ounces; the M6A1 weighs 20 ounces.

e. Capabilities. The average soldier can throw either grenade 35 meters. The grenades emit a dense cloud of irritant agent for 20 to 60 seconds

f. Color and Markings. These grenades have gray bodies with a single red band and red markings. (Under the standard color-coding system, the single red band and markings indicate nonpersistent riot-control filler. A double red band and markings indicate persistent riot-control filler, and any combination of green bands and markings indicates casualty-producing filler. Currently, there are no casualty-producing agents in hand grenade form.)

The Miniature CS Disseminator (mini-grenade) and XM58 CS Pocket Grenade (pocket grenade) are small lightweight point source disseminators. These can be seen on some SOG photos, most noticeably photos of Ken Bowra.
