Note: Updated the version tag, since this is still an on-going issue. Also edited first post since I now know how exactly it works.
This ability seems to be rather impractical. Currently, the Hetzer can use its camouflage, and can turn the chassis, but it cannot turn it's turret left or right (Note - The frontal main gun can be turned left or right to some degree, before the Hetzer is forced to turn the entire chasis)
Since it cannot turn it's main gun left or right at all, this means in camouflage, it can only fire within a very limited range. In most cases, the Hetzer will appear to be aiming at something but will never fire.
Now that this is a balance thread, here's some things to think about:
-Do you find this ability useful?
-Is it practical?
-Does it need a reworking?
I suggest allowing the Hetzer's main gun to turn left and right like it can out of camouflage. This will allow the Hetzer to fire on something while locked-down.
