Is overpressure realistic?

exactly my point, it’s odd that IFVs suffer less from overpressure. Doesn’t make any sense.

Or the real world example of the Churchill III AVRE being used vs a Panther in an unexpected engagement in France. Round detonated on a power line considerably above the tank, tank was intact, but it wasn’t moving anymore afterwards. I don’t know if said crew was pasted or just all the electronics were fried and it could no longer move.

The noise and vibration alone would probably knock out most people unconscious for a few minutes given the amount of explosive in there. Another example is the SU-122 being used as a tiger tank killer, using the power of the HE shell to knock out the turret crew from the sheer power of the explosion (and also breaking the turret ring).

Meanwhile you can shoot an ikv73 5 times with an 122mm shell in the turret and nothing happens

I still love the fact I once got overpressured as a Maus because a heat shell penned my lower front armor.

Except my turret crew died in the process for 0 reason they’re 5 meters away in another fully separate armored compartment bruh

If only VIDARs could also do that when I shoot 7 shillegahs at the thing trying to find the damn loader t posing somewhere

Or me shooting an M18 5 times with a long 88 prior to hull break being added and having to finish it with an HE shell.

Type 10 frontally killed via HE because it hit an external metal container. O U T S T A N D I N G.

Currently thats how overpressure works, it doesnt need to enter crew compartment, it seems to only need to overpressure at least something.
If i will be able to find it I will send clip of IS-4M getting overpressured in same scenario.

Definitely overdone in its implementation. There are reports from WWII of Soviet SU-152s and IS-2s shooting tigers and tiger IIs with HE rounds and blowing their turrets off with those rounds and the US would use 155mm guns and once a 203mm howitzer against Panthers once or twice and it had similar results as the Soviet 122mm and 152mm guns. Interestingly, the Brits tested their tanks throughout WWII during their developmental trials and found them pretty much immune to HE rounds up to 155mm. Cold War tanks with more efficient armor and armor density and angles help deflect the blast waves that would create overpressure. Then factor in with hatches closed most cold war tanks had slightly overpressurized interiors to help prevent fumes from entering the tank after firing. Overall, against medium, heavy and MBTs HE really shouldn’t be killing those tanks from overpressure mechanics. Light tanks, armored cars should get damaged from HE. Keep in mind, HE’s real power is in it fragmentation against infantry. Now bombs and large caliber naval gunnery striking against or near a tank is a different story as that is significantly higher explosive yields.
