Drawing of AN-M8 smoke grenade

The AN-M8 Smoke Grenade designated as the Army/Navy Model 8 HC Smoke Grenade (AN-M8 Smoke HC) is a U.S. military grenade used as a ground-to-ground or ground to air concealment or signaling device.

History[edit]

Developed in the 1940s, using a sheet-steel cylinder body that can emit a dense cloud of white smoke that would last from 105 to 150 seconds.

The AN-M8 was used extensively by American or other allied forces used throughout World War II to the present.

Details[edit]

It is used for smoke screening, target marking, and signalling, although the M18 colored smoke grenades are mainly used for the latter.

Warning[edit]

  1. THE AN-M8 HAND GRENADE PRODUCES HARMFUL HYDROCHLORIC FUMES THAT IRRITATES THE EYES, THROAT, AND LUNGS. IT SHOULD NOT BE USED IN CLOSED-IN AREAS UNLESS THE USERS ARE WEARING PROTECTIVE MASKS.
  2. WITH BOTH THE AN-M8 AND AN M18, THERE IS DANGER OF STARTING A FIRE IF IT IS USED IN A DRY AREA.

Field Instructional Use[edit]

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.
