The AN-M18 Colored Smoke Grenade is a US Army grenade used as a ground-to-ground or ground-to-air signaling device, a target or landing zone marking device, or a screening device for unit movements.

Potential hazard

With both the AN M8 and AN-M18, there is a danger of starting a fire if it is used in a dry area.

Field Expedient Use

When employing the M18 or AN-M8 HC hand grenade, it may be desirable to use one of these grenades without the fuze. To do this, the following procedure should be used in combat only:

1. Remove the tape from grenade bottom to expose the filler.
2. Remove the fuze by unscrewing it from the grenade.
3. Ignite starter mixture with open flame.
4. Immediately throw the grenade to avoid burn injury.
