 (1)           Grenade, Hand, Smoke, Colored, M16 = igniting fuze M200A1 – Sulphur, Potassium Chlorate, Sodium Bicarbonate                   and dye filler – tinplate smooth cylindrical body - 50 yards range – 2 seconds, full volume after 3 seconds – blue-gray color with                   SMOKE (COLOR dye), ˝” lower band, all in yellow color – signal use - approx.use 1943-1944

Remarks : first fuze used was the M200 type . Although introduced in November 1942, the M16 smoke grenade was however quickly declared ‘substitute standard’ due to insufficient smoke volume capability . Initially 8 color dyes were used i.e. blue – green – orange – red – violet – yellow – black – white, later however, blue was dropped – in the end, only 4 basic color mixtures were retained red – yellow – green – violet (while the others were declared ‘obsolete’, but in fact never cancelled) . Grenades filled with colored smoke are mainly used as signals for air-ground and ground-to-ground communication .


Grenade, Hand, Smoke, M18 : characteristics are similar to above type, this new model replaced the M16 Smoke Hand Grenade, because of deficiencies, already superseded by the new type, November 16, 1943 . Main difference, it burns 1 minute only.

 (1)             Grenade, Hand, Smoke, Colored, M18 = igniting fuze M200A1 – Sulphur, Potassium Chlorate,Sodium Bicarbonate                   and dye filler – tinplate smooth cylindrical body - 50 yards range – 2 seconds, full volume after 3 seconds – blue-gray color with                   SMOKE (COLOR dye), ˝” lower band, all in yellow color – signal use - approx. use 1943-1945.

Remarks : total WWII production of M16 & M18 Smoke Grenades reached almost 5,000,000 units .


Grenade, Smoke, Red, M3 : special type of chemical grenade developed in 1942 for Army and Navy, for possible use as emergency signal . The body of the grenade, although similar in shape, is larger than the usual chemical grenade . It is intended for use as a signalling device and comprises three metal fins at the top which can be bent upward to serve as additional bases (stabilizers) so that the grenade will not sink below the surface when placed upon snow, mud, or swampy ground . Here come its main characteristics :

 (1)             Grenade, Smoke, Red, M3 = igniting fuze M200A1 modified (cut off lever) – Sulphur, Potassium Chlorate, Sodium                    Bicarbonate and dye filler – steel cylindrical body - not thrown – 2 seconds, full ignition thereafter – blue-gray color with                    SMOKE, RED, ˝” disrupted center band, all in yellow – signal, emergency use - approx. use 1943-1945

Remarks : both M200A1 as well as M200A2 fuzes were used . The red color dye burns for about 2 minutes and 20 seconds . A total of 155,725 M3 Smoke Grenades were manufactured between May 1943 and June 1945 .
