The Main battle tanks: Kuma, Varsuk and Slammer.

These tanks seems to be affected by the faulty zeroing.

All tanks when zeroed to 1900m on main turret, the machinegun will be firing as it was zeroed to 100.
It is very easy to see the problem, when you zero to 1800m and hit 1800m perfectly, then switching to 1900 and the gun now fires like zeroed to 100m
