A smoke grenade is a canister-type grenade used as a signalling device, target or landing zone marking device, or as a screening device for unit movements. Smoke grenades generally emit a far larger amount of smoke than smoke bombs, which are a type of fireworks typically started with an external fuse rather than a pin and are more complex. The phrase "to smoke", meaning to fake, bluff, or beat around the bush, comes from the military usage of smoke grenades to obscure and conceal movement.
