This grenade is fired from a 66 mm smoke grenade launcher such as the Kaha Type 270/M239 system described in the previous entry. The grenade is electrically fired and produces a smoke screen 30 m wide lasting for a period of 90 seconds, although this does depend on the weather conditions.

The grenade consists of a metal housing containing the propelling charge and fuze and a black rubber case filled with a pellet of red phosphorus mixture which, when ignited, bursts the case and produces an immediate cloud of smoke in front of the vehicle.

The calibre of 66 mm is normally associated with UK and US type smoke grenade systems.
