So they are actually nerfing the gun depression but prove me wrong here please
-7.4 is BS and I can prove that the 2A8 has -9 by using a simple photo of it irl

The above image is what I will use to prove it (as you can see the gun is at its lowest here in this image).

As you can see in the section of the tank I am using to prove my point the angle of the composite on the side of the turret must match the angle of the composite of the gun mantlet when the gun is at its 0 angle which we can observe in game and irl in all leopard tanks.
Using my above point in the caption if I use 1 reference line and measure the angle between that ref line and those 2 highlighted lines and take the difference, it should give me the actual angle of depression.

First reading gives me a value of 52.4 degress whith the horizontal which I have highlighted in the corner

2nd reading gives me 61.8 degrees whith the horizontal Which i have highted in the corner
So if we take the difference we get -9 degrees EXACTLY.
IDK what more there to prove
