This utility model relates to the technical field of riot control ammunition, specifically a hand-thrown incendiary colored smoke grenade. It includes a casing containing several evenly distributed smoke column fixing chambers, each chamber containing a colored smoke column. The casing also contains propellant tablets that contact the colored smoke columns for ignition. A propellant strip for igniting the propellant tablets is also present within the casing. An ignition mechanism adjacent to the propellant strip is also provided on the casing. This ignition mechanism includes a delayed ignition tube for firing the propellant strip. The delayed ignition tube in the ignition mechanism can be precisely fired, igniting the propellant strip. The propellant strip then transfers the flame to black powder tablets made from a mixture of potassium nitrate, sulfur, and charcoal, ultimately igniting the colored smoke column. The entire ignition process is orderly and efficient, ensuring reliable ignition of the colored smoke grenade when needed. Smoke colors: red, yellow, green, and white. Having four smoke colors allows for the transmission of more signals on the battlefield.
