This grenade closely resembles the H.E. stick grenade 24 in external form and size. However, instead of the H.E. filling this grenade is filled with a Berger smoke mixture. There are eight holes in the base of the head through which the smoke escapes. The handle has three horizontal corrugations at the screw cap end to assist in differentiation by touch.
Insert the friction igniter into the handle and then place the open end of the flash cap into the recess in the top of the friction igniter, finally screwing the head onto the handle. Then, by removing the screw cap and pulling the igniter, the delay is ignited and the grenade may be thrown. Smoke is emitted for two minutes. Because of the short duration of the smoke, this grenade is used where accuracy in placing a small screen is most important, such as screening machine gun nests and pillboxes.
