So now ammunition stat cards have a new thing added to be very clear!!!
“Armor penetration by high-energy action”
This means how much penetration you have with raw HE power. It does highlight how useless HESH is of course because these numbers are not indicative of how useless your rounds are as HE weapons at all.
The Ammunition details between M1 and L33A1. Note the nearly double amount of HE included in L33 and that L33 does allegedly have a greater amount of penetration “by high energy action”
Spoiler
The issue: This penetration does not kick in unless you’re really really up against the plate, whereas any other HE type can overpressure via HE from a serious distance, (including HEAT!)
Spoiler
155mm M1 overpressure killing via HE hitting the roof at a serious distance:
165mm L33A1 (with greater penetration in HE terms and nearly double the HE quantity) doing no damage at the same spot:
In fact look how far down you have to go for HESH to do any kind of HE damage:
You have to be essentially touching the roof to do any kind of HE damage.
And in spite of this information, rounds like HEAT and APHE don’t seem to have the same issue, they will overpressure via HEAT at fairly impressive distances considering their purpose and HE quantity.
Examples here are 122mm HEAT-FS and 125mm HEAT-FS.
Now these aren’t quite the same distances as with 155mm M1 but considering these are HEAT type rounds with less than 3kg of TNTe it is a bit impressive.
Or like here with KV-1 SAP and 120mm L31, the latter of which has much more HE and “energy penetration” but clearly cannot HE kill at the same range.
