and Yes, I understand Arma 3 3 is not a Vehicle simulator, but MBTs are a core element of Capture the Island - BECTI - Zerty Editon, and thus quite important, as the Tanks surviability decides the winner. We are having MBT standoffs everyday, on 4km, on 150m, against static Titan AT or RPGs out of a Window.

We are already using a scripted version of Raphaels Trophy System, as it can be found on the Slammer / merkerva Tank to protect the Tracks against missle hits.
The issues still exists with the 120mm ASPDSDF-T rounds, or AP rounds in general.

Was not able to reproduce the issue i had to put 3-4 rounds into kumas tracks to destroy it. Could you please provide more info? Thanks!

This video should proivde the steps to reproduce the problem at hand:

If you request further details be more specific: A list with the components that were damaged? or precise distance?

Why dint you use the Virtual Garage? There is a Kuma model where you can see what gets hit.

The Virtual Garage Vehicles are fakes, their hitboxes are not matching the actual model.
The Virtual Garage also does not show the destruction of the vehicle. Parts meight show red, but the vehicle would surive....
Also some hitboxes on the Commander Turret of the Kuma and the Tracks of the Kuma are missing (against lower calibers such as 12.7mm APS, Commander turret can not be damaged at all)...

Thus the Vehicles in the Virtual Arsenal are useless.

#EDIT#
Virtual Arsenal is showing the same effect, hull and tracks are being destroyed, even though the round only goes through the tracks

Hi Yoshi_E. Bullets today expensive. From the point of view of economy it isn't favorable to spend one bullet for one tank. I offer new, effective firing.)))

Sometimes and all four. More in a row I didn't try to put.
I know, at you it will turn out five))).
This test thanks to your ticket.
The truth my video is more about permeability of a shot.
