RIght first, critical error in misunderstanding tank destruction mechanics, the test drive is a terrible place to test tank destruction.
Because none of the tanks in there have crew (some show ghost crew members who arent actually there, you can actually hop right into any of the tanks on the test range because of this), it doesnt allow for the in game tank destruction mechanics to work as intended.
Its why if you abandon your tank, your tank often takes more hits to kill, while as long as you kill all the crew in the tank, the tank will instantly explode, this works as well if say the commander alone is outside the tank repairing it.
IE. If you kill 1 crew member with no one else in the tank, that tank will instantly be destroyed, you can easily test this with an ATR in a match if you like.
Now Try again with the 4E and 4F1. Completely missing the mark there. But dont worry, this issue can be fixed by moving the Stug to BR2.
Still isnt the reason, as I have explain already now, but do please continue to not read what I type.
Well see thats the funny thing about the Stug 3F, there is nothing on it that justifies its existence at BR3, from its cramped (therefore easy to OHK) crew, casemate nature and lackluster armour.
I mean we have been over this no?
What about the Stug 3F is BR3 material, and dont say the gun, because even that isnt as its the much inferior version to the other long 75’s.
