A little hidden aspect of this patch, a buffed K2. Turret face now provides approx 1000/1500 of protection against KE/HEAT, with the mid-hull providing about 850/1200 KE/HEAT. Turret ring is still 770 against HEAT, and LFP protection is still inconsequential (effective only against autocannons), and according to the armor viewer the T15's missiles can still hit the turret ammo rack through the turret ring weakspot. Also, something interesting:
Apparently K2 is a wheeled vehicle.
edit:
They also removed the weirdly strong turret roof armor.
