>the main gun's depression is a crime.
It's possible the model has limited depression so that you can't accidentally model it pointing down, if you want to leave it able to move, it won't droop down over time, or something similar.

It's good to remember than in real life gun depression isn't that huge of an issue. It's good to have some, but a tank with less depression isn't automatically worse than a tank with more depression. Unlike in a video game, in real life you can do a lot of things to work around poor depression.
