The M243 smoke grenade launcher uses rounds filled with red phosphorus. Upon activation, a dense cloud of white smoke is created from ground level up to a minimum height of 7 metres (23 ft) and between 20 and 50 metres (66 and 164 ft) from the vehicle in 2 to 6 seconds. The cloud lasts 1 to 3 minutes depending on wind speed and other weather conditions.
