SMOKE GRENADE LAUNCHER KIT M113A2 AND M1059. This kit allows
installation of two smoke grenade launchers on the front of the carrier below the
headlights. The smoke grenade launchers enable the carrier to generate a smoke
screen to conceal the carrier from enemy observation. Each launcher contains a
discharger with four launch tubes that hold one grenade each. The arming firing
unit (control box) is mounted on the firewall in the crew compartment.
