The Sledgehammer was a heavy self-propelled gun. It was one of the heaviest artillery in HS Co's arsenal. 380 mm howitzer as the main gun, it surely designed to do serious business. The Sledgehammer was the solution when busting bunkers is needed when you dont have air superiority. Sledghammers usually deployed with one medium tank or main battle tank and one self propelled anti aircraft and if available, one radar truck. Sledgehammer have two modes. One is travelling mode and one is siege mode. It is recommended to use siege mode before firing, to prevent smokes trapped inside the vehicle. According to the manual, press G to change between travelling and siege modes. As for the firing control, VTOL and Trim to adjust elevation and horizontal turret rotation. Activate Air-To-Ground mode, fire with FireWeapons control (default Alt on PC). It was supposed to fire every 30 seconds, but you know it's not fun if i keep it that way, so it fires every 3 seconds (please dont spam).
