This weapon would be a Anti-Ground Vehicle weapon.
For those that don't know what a rail gun/cannon it's a weapon that fires/shoots a round, that doesn't use gun powder/fuel, but uses a EM field an could put a hole in a tank. Like cutting a hot knife throw butter.
The way it can be used is that 2 hits an can take down a Scorpion or Necris
ground vehicle = to the Scorpion, in armor. But the Hellbender/Goliath take 3 shots, an for the Leviathan or Necris = to will take 4 shots to take out.
And if you/enemy player(s) try to link/repair a vehicle, an lock on from the rail gun/cannon is fired. Meaning unlike the AVRiL, you have to lock on to a vehicle with/without a driver/player(s).
