Lore: Moments before reinforcements arrived, the Alliance was fighting the Ravage: Rebuilt. The alliance shot at it with anti-vehicle rifles and missiles. They damaged its amour and the mech can barely stand. They finished it off with a fully charged shot from the Shatter Tank (the one they used to take back Sal Macha). It knock down a near by wall and tree and both fell down on the mech digging it into the ground.
