STD Destroyer / Heavy Artillery
1 Multi purpose light drone
1 Combat AI
Here you can see the crewman standing at the mission control station.
Beside him are the energy cores for the cannon.
Behind him is the Multi purpose light drone.
Inspired by The German Ratte Tank and Kaplan's Hyperion Tank
I think my STD will have two of these big guns for the main turret.
(I think it has the largest cannon for a ground unit but, i could be wrong)
