Discussion on ZTZ99A model errors in game

SO ZTZ99A does have exactly same armour as ZTZ99?

have you tried sending an email to 1080p? or more administrators. Using this method to bypass issues.

[141_allen]

I think a few of them noticed the complains, but are coordinating with other guys like TrickZZter to solve it, give them a bit of time.

99A turret nera hitbox not match x-ray view and reality. // Gaijin.net // Issues (Rejected)
(New) 99A turret nera hitbox bug. (source added) // Gaijin.net // Issues
In ZTZ-99A’s turret, after the modelling update, the bottom of it’s turret shows a suddenly armor value drop, from about 800mm to about 400mm and lower in lower part. (pic1, pic2, pic3)
From x-ray vision, we can know the armor structure of 99A in game. Compared to the reality, it’s basically same structure, the nera in armor pack fully filled the turret, so in the following part, I will use X-ray view as sample as it’s easier to measure and explain. (pic4, pic5, pic6)
I screenshotted armor view and x-ray view structure from same position, and photoshoped them together, they fit perfectly, no gap. The nera fully filled the armor pack(green 20mm steel box), and placed over the turret ring armor(orange variable armor) without gap. (pic7, pic8)
From armor analysis, we can know the armor of it’s thickest part is from 800-880mm ke, fits the acknowledged PPT from official lecture(over 800mm ke protection).(pic1, pic2)
The armor’s weak point in bottom is about 350-400mm ke by test in armor analysis. (pic3)
We can know the attack angle of front 20mm plate is 39°(pic1), and the back plate is about 63°. (pic9)
20mm rolled armor at 39° is 26mm, tested in WMA-301, test ammo is DTC-10 from ZTZ-99A.(pic10 )
And we know this armor equal ratio won’t change by angles, so 65mm back plate in 63° is 65*38/20 =123.5mm. (pic11)
So turret armor without NERA is 26+123.5+250=398.5, close to the test result, the inaccuracy could be from angle measuring inaccuracy, attack angle inaccuracy, or other problem. All in all, it fits the results.
So there should be some bug, possibly a gap in ZTZ-99A’s turret NERA hit box. From test in armor analysis and custom battles, the gap is about in this area.(pic12)
The armor value of the bottom shouldn’t be so low, it’s still part of the turret’s main armor, APFSDS need to pen ERA, armor plates and the whole nera to reach the crew, and shouldn’t be such a steep drop in KE(CE behaves similar).

warning many pics

@InterFleet can you check the issue with the hit box?

[EnglishTeaKett1e]

Turret hitbox issue can still be fixed, but the underperforming UFP armor will be difficult. All I know is that 99A irl should have 250-260mm thick UFP unlike 220mm ingame. But this will be extremely hard to prove to Gaijin, and the only source we have is the PPT showing 7xxmm vs KE without ERA, and 8xxmm with ERA.

I’ve recently had a look on some Abrams spall liner reports, they just used a photo and an book about tanks, and they managed to get the issue passed by TrickZZter, like I thought he said they are not valid at all. Plus I could literally see welding marks on the inside of the tank in picture.

Turret hit box report

99A turret hit box error // Gaijin.net // Issues

Spoiler

[NCC105]

@NCC105

you missed a part.
it’s a V shape cpmtaining 2 blocks
together they filled the nera. The triangle hole is used to keep the nera thickness homogenic

[MirageTank1]

I didn’t see it in the game.
I can see two parts in the turret of WZ1001. But there is only one in the 99A turret.
TZ says it does not accept data mining. So how to handle it is Gaijin’s matter.

[NCC105]

hit the turret higher, it will pen through the first block and reach the second

[MirageTank1]

yea,but the main issue is that LOS close to 650mm only has an equivalent thickness of 350mm.
see how Gaijin handles this evidence.

[NCC105]

[MirageTank1]

ok， I will include this picture in the report.

There is another issue, when shooting at the bottom gap, Remove the 250mm gain brought by ERA. NERA only has 100mm .

[NCC105]

@MirageTank1

NERA only has 100mm

it’s the armor plate, 20mm+65mm, there are detailed calculating process in the issue I post before.

[来如雷霆收震怒 罢如江海凝清光]

Maybe we can discuss this directly in the forum? And not discussed in this topic. It’s just that in this topic, most people don’t know about the hitbox model error.

[NCC105]

then we need a new thread, concerning this but new. There was a thread about this problem, but closed and merged into this, because it’s still “model errors”
