For top tier it’s not going to make the greatest difference as APFSDS will always be superior to HESH, but it would still provide SOME use in some situations.
HESH state is laughable. The actual listed armour penetration is never applied and the shell instead just relies on its HE fragmentation, which is one-directional instead of spherical, so it’s literally a worse HE shell. I tried to play the FV4005 and my Centurion AVRE purely for fun - after my AVRE hit the front of a T-44 and a Sherman and only took our barrel/tracks, and my FV4005 hit the side armour of a T44 straight-on just below the turret for barrel and track damage too, I gave up.
A HESH shell of even 105mm hitting the side plate of most tanks should warrant the crew being reassembled by air crash investigators. Yet a 75kg projectile can be lobbed at a T44 at 700m/s and somehow the vehicle is still touching the floor.
@Gaijin if you want to be lazy then literally just model HESH to act as a regular HE shell. HESH doesn’t act as it should anyway, it makes no difference. At the very least the tanks that have HESH-only access will be slightly less unusable.
