This german assault gun is made of a 38cm mortar mounted on a Tiger I chassis. This build in particular is made for the "Alternate WWII" roleplay, wich is why the machinegun doesn't work. The interior has been improved scince my Tiger I, I added some ammunition and crates as well as a few more controls for the driver and some seats. Drive with AG1, AG2 is to aim (both controls are Pitch and Roll), AG3 fires the mortar. Also VTOL raises the gunners seat to the loaders position (camera 2) and trim opens the mortar barrel to reload. Yaw turns the crane in the back. Camera 4 follows the bomb.The Sturmtiger was built for urban warfare, so it will hopefully help keeping the allied out of London.
