Now before you scream "UNREALISTIC!" Everyone has called the tank a rail-gun tank because not many people are educated enough on the subject of weapons like these. Coil-Guns are basically better than rail-guns because the barrel doesn't get worn down, still a high speed projectile, not a futuristic weapon as I have even made one with household electronics which could go through the wall as i accidentally found out.
This is only for if BIS truly intends to remove the Coil-Gun tank because tehy believe its not realistic.
