ERA not detonating when hit by KE round

[CCRcmcpe]

Mods (complete and add to the following information):

• Arma 3: 2.06.148581 [e.g. 1.00 stable, rc, dev]
• CBA: 3.15.6 [e.g. 3.0.0 stable, commit hash]
• ACE3: 3.14.1 [eg. 3.0.0 stable, commit hash]

Description:
As in the title. Most of the time (95%) ERAs will not detonate when hit by AP, and seems they almost always providing protection against AP.

Line 362 in 2f22804

if (_warheadType isEqualTo WARHEAD_TYPE_HEAT || { _warheadType isEqualTo WARHEAD_TYPE_TANDEM } || { 0.05 > random 1 }) then {

Steps to reproduce:

1. Place a T-100 and a Merkava on the map.
2. Get in Merkava as gunner, shoot T-100's upper glacis ERAs from front using AP.
3. You will see ERAs not detonating, and T-100 is hard to destruct when just shooting the upper glacis.

Where did the issue occur?

• Singleplayer / Editor (Singleplayer)

This is unrealistic because Russian tanks like T-14 installed ERAs which offer KE protection and they will detonate upon hit.

I wasn't aware that ERA offers KE protection when developing this. Would this be a universal feature of ERA, or does specialised ERA counter KE?

In vanilla Arma 3 all ERAs provide some protection against KE as they reduce velocity of incoming shells. ERAs on Merkava provide 10% of reduction, on T-100 and T-140 it's 35%. See https://armedassault.fandom.com/wiki/ArmA_3_Vehicles#Tracked

In reality, AFAIK only some late Russian ERAs provide protection to KE, like Relikt. Other ERAs may have effect but not much, same as Arma 3 modeled.

Pretty much all ERA should provide protection to some degree against APDS and APFSDS.

The penetrator enters the ERA block which detonates, and then the outside panel pushes away, either rotating the penetrating rod and bending or even snapping it in half depending on the angle of the impact.

Newest US fin rounds have a small steel section at the front that's meant to break off on ERA hits and allow the DU to continue properly into the target.
