Warning, this post is very picture heavy
B1 - no changes, apart from the track armor being increased from 20 to 25mm
FCM 50t: nothing much, just the rear wheel thickness changed
Some significant changes there (if you could say so), the gun shield is no longer 15 but 14,5mm, upper frontal plate is 8mm thick and the nose is 13mm thick
Strangely enough, despite the collision model did change its shape, the visual model didn’t. In 8.9 the Marder gunshield and superstructure are 8mm thick (the old one is the one with orange “ears”). The sloped plate was reduced from 15 to 14,5mm.
Jagdpanzer E-100 – track model changed, the one with more “teeth” is the new one. The E-100 suspension model was changed the same way.
Tiger I recieved a buff: the orange “weakspot” (in 8.8) behind the turret (60mm) was buffed to 80mm (red)
The mantlet was slightly changed too, the one with the more lighter zones in the new one (no big difference though). Overall it’s a buff, the colors change a bit because there were more spaced armor zones added.
Tiger P armor was improved the same wasy as Tiger I was last patch. The machinegun weakspot was removed and the copula is thicker (95mm, earlier it was 70mm). The mantlet is more complex. The darker zones don’t however generally mean thicker armor, but the fact more armor zones were added and the old ones were recolored.
The hull remains the same thick (100mm front), but the stock turret armor has improved (from 100 to 120mm), furthermore the stock turret weakspot above the frontal turret plate (the green zone) is now gone. Stock mantlet was made significantly thicker (100mm). The rest is the same (despite changing colors)
Furthermore, the top turret mantlet has been reworked. Earlier, it was 120mm mantlet with 120mm behind it, now it is 120mm mantlet (the largest part) with probably 60mm behind it (the orange part). The turret is also slightly smaller and the turret copula is shaped differently.
E50M model was changed slightly: the gun was moved a bit down
Tortoise is marked as changed, but there are no visual changes apart from several shadows on the hull. Nothing worth noting. Same goes for Cruiser Mk.II
Sexton II model was changed slightly (with corresponding damage model correction), the gun was moved higher (the one with the cradle protruding up is the new one)
T110E5 armor – judging from the gamemodels3d (wot viewer shows no real difference), T110E5 lost the viewports as its weakspots. New model:
KV-1S model was also changed. For starters, the tracks and the hull were made slightly wider:
But the armor model was changed too. The vehicle lost the machinegun and driver’s hatch weakspots. It however also lost the thick weld strip on the front hull point where LFP and UFP meet.
The changes log also shows a change in T-150 top turret armor, the only difference is that the “hole” behind the mantlet was nerfed from 40mm to 20mm apparently.
The rework of the IS-3 model was extensive. Here it is from the front (the darker one is the old one).
This is the top turret configuration (again, darker one is older one)
The armor model also changed: the lower turret gained a lot of armor, but I guess we are more interested in the top turret. The top turret armor was changed from 220/220/220 to 249/172/100. The front is tougher, but the driver’s hatch is now a bigger weakspot. However, the turret loses a large chunk of its tough zones and the rear of the turret is now quite vulnerable (as you can see on the gif).
IS-4 armor was also changed. It recieved the awaited frontal angle buff and the mantlet is also somewhat different, covering more area. It’s a buff, but not a big one.
And finally, Object 212A model has been reworked (the wider one is the new one)
