Regarding the issue where the frontal armor of some vehicles fails to absorb bullets

[君则]

Let’s take a post about VT4 on the forum as an example
[关于VT4首上装甲接缝处无法正确触发跳弹机制的issue]( 关于VT4首上装甲接缝处无法正确触发跳弹机制的issue - National Communities / 中文分论坛 - War Thunder — official forum)
Here are some speculations about why this phenomenon occurred, and it also explains why, under the same angle of incidence, the M1 series can function normally while the vehicle with multiple layers of armor on its front cannot.You can use AI translation to read it.
Meanwhile, the author of this post also submitted the relevant issue at that time, however…

VT4A1 upper glacis joint seam ricochet failure
(I have serious doubts as to whether the administrator actually understood what we were saying.)
In conclusion, that’s it. I hope everyone can join in the discussion to bring this issue to the attention of the authorities.

Taken from content in development

This is taken from the official version.It can be seen that there is improvement, but is the problem completely resolved?

When hitting multiple armor seams and the edges of reactive armor, ricochet angles will still be ignored and penetrate the armor.This problem has improved but is not completely solved.

The same as Leopard 2 PSO/2A7 that soak up shells and 122A/B that absorbs it virtually with the same armour package
