Here we have the discoverable armor changes plus a shot showing the reworked collision model for the suspension.The turret stays unchanged. As before old on left new on right.
From the front only the suspension collision model is changed (The blue part with the tracks which is a no damage hit box).
From the back both armor and model stay the same.
The side armor even though much thinner can still become an auto bounce the lower down the hull you aim if you are too close or high.
