An Auto Launcher is an Imperial vehicle-mounted Grenade Launcher similar to a Smoke Launcher. They are six-barreled launchers mounted on an Imperial vehicle chassis and capable of firing salvoes of grenades three at a time. An Auto Launcher can be loaded with Frag Grenades, Krak Grenades, or Blind Grenades and are useful providing a close-in defence of an armoured vehicle or blinding the enemy by releasing a smoke screen around the vehicle. An Auto Launcher carries a magazine of 6 grenades, always all of the same type.
