A Smoke Flare is a hand-held flare that emits both a bright light and a pillar of colored smoke for 15 minutes. Once set off they burn constantly and cannot be shut off. Sighting in either day or night is nearly automatic in line-of-sight. Smoke flares are specifically designed to be handheld or implanted in the ground. Exercise caution in dry conditions, as the flare can ignite flammable materials.
Flares are designed to emit one of a variety of colors: white, green, red, yellow, purple are the most common.
