A Signal Smoke Grenade is a device used to produce a dense cloud of colored smoke for signaling purposes. These grenades are often used in military operations, search and rescue missions, and outdoor activities to communicate locations or convey messages. The smoke can be seen from a distance, making it effective for visual signaling. Typically, a signal smoke grenade is activated by pulling a pin and throwing it, releasing a burst of smoke. The smoke can come in various colors, such as red, green, or yellow, each serving different signaling meanings. They are designed to be safe and non-toxic, ensuring minimal environmental impact.
