Description: These grenades have four smoke ports in the head. These are covered by small squares of adhesive tape. The Grenades M18 produce seven colors of smoke; red, orange, blue, green, black, violet, and yellow. The M16 is a limited standard colored-smoke grenade and differs from the M18 in that it produces smoke for 2½ minutes, while the M18 produces smoke for one minute, and the AN-M8 produces a white smoke for three minutes.

The Fuze M201 threads into the top of these grenades. It is essentially the same as the M10A3 used in the fragmentation hand grenades. However, there is only a two-se-cond delay element, an igniter, and no detonator. This results in a fuze with a much shorter body. At the top of the body, one side is extended to form a lip for the attach-ment of the safety lever; the other side forms a hinge to carry the spring-loaded striker. The striker is restrained by the safety lever. The lever is hooked over the lip of the fuze body and extends across the head of the fuze, over the striker, and down the side of the grenade. The lever is held in position for shipping and handling by a split safety pin which passes through the safety lever, through the fuze body, and over the striker, to protrude on the other side, where it is spread so that a pull of between 20 and 30 pounds is required to withdraw it.

Operation: The ingiter ignites the starter mixture, which initiates the smoke mixture. The pieces of adhesive tape covering the smoke ports are blown or burned off, and smoke is emitted for approximately 3½ minute.

The volume of smoke generated by a grenade is generally too small for screening pur-poses. Although these grenades may be used to patch gaps in a larger screen, the au-thorization is for signals.

Remarks: The presence of moisture will cause these grenades to ignite spontaneous-ly. If a fire should occur in such munitions, an attempt should be made to remove and segregate the burning items. Neither water nor the usual chemical extinguishers should be used in an attempt to extinguish such fires.

The Smoke Grenade M16 is designated as a substitute standard item.
