These pyrotechnic canister grenade provide a continuous discharge of smoke under pressure. Three choices of composition are available. CN tear agent, CS riot control agent, and inert white smoke for training, screening and tactical purposes. The Model 52 series is a full size grenade. The Model 62 series is medium sized having the form factor of the military M83 smoke grenade. The Model 82 series is compact in size allowing it to be easily carried in ammunition vests.
