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
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.
Guys I just got my maus overpressured from a 105 HE shell hitting my engine bay straight in the center.
Correct me if I’m wrong but I feel like the fact there’s a giant metal plate in front and behind the engine should probably not allow an overpressure of the WHOLE CREW at once.
Seems like compartments aren’t even taken in account ? That’s just silly for a pressure mechanic
Its a real thing. The way it works in war thunserbis complete bollocks, and it shouldn’t apply to aphe shells
Without overpressure, large caliber HE rounds would be useless in taking out armor in WT.
It’s not realistic, as a pressure wave isn’t a magical sphere but it gets deflected and loses energy in the process, thus a hit to hull or turret wouldn’t, in general, cause lethal pressure in the other area of the tank.
So it’s really more of a gameplay mechanic.
What is however very unrealistic is overpressure APHE. Since Gaijin only consideres the explosive value to cause the pressure but not that that explosive is trapped inside a thick steel case.
A larger explosive amount is irrelevant, when the shell also grew in size and therefore requires more explosive to break up.
Simply put, overpressure APHE makes no sense in it’s current implementation, just like the damage from APHE shells, that defy physics.

Not above it - gunner aimed at the turret ring but round hit a power pole about 3 feet (.9m) from the panther - lots of references to it eg Churchill A.V.R.E. - Tank Encyclopedia
OVERLORD'S BLOG: A Bad Day
Its sad how a HE with 5kg does damage but 21KG TNT worth HESH does nothing.
Yeah, hullbreak was a absurd shitshow
Not at all. Overpressure is a half arsed and inconsistent mechanic worse done than hull break.
some AFVS will overpressure from HEAT hitting a tyre which is nonsense. and HESH is not even close to as potent as it should be. let alone the lack of a scab spall from it,
Heres 160mm HESH (predecessor to the 165mm HESH on cent AVRE) in real life vs WT, It just kills turret crew and doesn’t really do anything else at all, it shouldn’t leave anything operable in the tank at all. A full HESH penetration like this is no different to HE, the crew would be a pink mist
Also here’s what happened to a centurion in a FV4005 test cant upload the video but here’s screenshots.

Well, that’s because WT HE penetration follows a certain formula, meaning that a 165mm HESH won’t penetrate 80mm with the explosive action.
A WW2 tank is also not the best example, since you never know about the armor quality.
If the armor is brittle it will fail more easily, thus it’s not really guaranteed that this would happen with every 80mm plate.
Of course in general it’s kinda a pointless discussion.
No tank should be operational after such hit, but in WT crews can magically fix up tanks on the fly, thus ammo that knocks out crews is simply the most effective.
Even though it makes like no sense that a 120mm going 1000m/s hitting a cannon breach is simply going to be repaired in 30s, when there’s nothing left to repair.
The repair mechanic makes tanks way to survivable. There should be a limit how much damage a module can take before it simply can’t be repaired.
We don’t need more stupid mechanics, like overpressure APHE or APHE nose flying through the tank, just to counteract an unrealistic mechanic that is the root of a lot of problems.
If a 75mm APHE with 30g TNT hits a T-34 turret, it doesn’t need to do a 360° explosion to knock out the crew in the hull, to take out the tank, when it just took out the turret traverse mechanism or hit the guns recoil cylinder.
Ammunition should be lethal, regardless what type it is.
Almost all shells have already unrealistic damage potential to crews, with insane spall cones, just to be competetive. When they just need to take out a vital module with a direct hit.
Gaijin does say there is a formula, however is is not based on realistic performance against armoured targets like at all it is pure fiction just as the “formula” for kinetic penetration is.
completley agree, yes there should be a blast radius on HE, and a blast cone on APHE (which was voted out by people that didnt understand what the vote was last year)
APHE shouldnt, its explosion wasnt like a grenade. Its not even consistent on anything but APHE. APHE shouldnt do much more damage than a solid AP shot either, british tests during ww2 proved that its not really worth the hassle and it just weakens a shell making it more likley to shatter.
Im currently working on a bug report to do with HESH and its lack of realistic damage. It currently just acts like it eats a hole in armour and spits out a little bit of spall, it should generate that little bit of spall and a “scab” the size of the impact zone inside of the tank or if its a full shell penetration obliterate everything with as much aggression as an ammunition detonation. Its unfair that some shells are modelled wrong, HESH is the worst offender but its very annoying when i use all kinds of shells and they dont behave as they ought
