I will copy paste what I have already answer on similar topic:
No one make any intentional errors with machines (or any other part of the game).
War Thunder is huge project, we have thousands of vehicles in game and errors can happen. Connecting errors with race, nation of origin or religion is just insulting and our forum (nor any other place) is not a place for such comments.
If you want to discuss specific vehicle, please use Machinery of War Section here: Machinery of War Discussion - War Thunder — official forum
If you found any bug with vehicle, please jump on our dedicated bug reporting website and submit valid bug report, this will help us fix the problem.
Please remember, that screens and detailed description will help and speed up the process of fixing.
Please do not post multiple SAME bug reports - this will slow down the whole process. Instead, create one, valid bug report with as much data as you can (and please remember, we do not accept confidential data :).
