My first A7V WW1 Tank Build. To use this schematic in its fullest I recommend the following mods:

Create, Create Trackwork, Valkyrien Skies 2, Vmod, Create Diesel Generatros, Create Big Cannons, Create Big Cannons Modern Warfare, Create Drive by Wire, Create Ender Transmission, Copycat, Copycat +, Rolled Homogenus Armor. Or use the Tank Tussle Modpack for easy use.

To link the Tank, use Linked controller on Link Hub under the driver seat to link the driving, use another linked controller on the Hub next to it to controll the elevation. (or use a Tweaked controller if preferable) 
Note: You shoot using the driving Controller "Space" 

Need to add fuze to the ammo in the ammo box.

To make it survival friendly just exchange the infinite ammo box for a barrell.

To assabmle just use the ship helm in the tank and then destory.
