Empires vehicles are all about customization. We can take this to the next level with interchangeable turrets that each have thier own weapon options. Turrets would receive damage without affecting the armor of the main part of the tank. Each turret would have its own weight, armor strength and turn speed. If the armor on the turret failed then the weapons would be disabled but the tank would not be destroyed and would be able to be repaired at a repair pad/engy Jeep. These turrets could be mounted on any tank chassis so long as the weight limit for said chassis is not violated. So, you could mount a heavy turret on a light tank but wouldnt be able to equip any armor due to weight. Light Turret: Fast turn speed, light weight, light armor, few weapon mounts. Open Turret: can mount level three canons, No roof, exposing driver/passenger to fire, medium rotate speed, thin armor. Rocket Rack: Several spots for rockets. Medium armor, heavy weight, fast turn speed. Medium turret: medium everything, Heavy Turret: Heavy/slow everything. Anti-inf turret: multiple MG/nade mounts. fast rotating speed, heavy weight, light armor. Etc. You get the idea.
