The old Ravager, fully loaded, as seen from the Command center.

RS-4 Ravager was a reusable, muzzle-loaded, single barrel cannon. It was a replacement for the perished RS-6 Impaler. It was destroyed in the 2012 meteor strike.

Ravager was first a fullauto-cannon with a top-loading four-round magazine (hence the name RS-4), but was stripped down to be only a single-shot muzzleloader. It was stripped after a projectile fell down to the ground from the barrel and exploded prematurely. As a result, the forest caught fire and the explosion damaged the fortified walls of the Command center.
