I think you need to take a look at the post name before you state that. What’s even the point in your argument at all if you aren’t saying that? This statement has made all of your comments pointless.
Why argue on a post stating something is up when you supposedly agree? What is your angle?
There’s a lot of confusion about the 279 online. Its odd hull shape was made to increase armor protection: it had to resist enemy AP and HEAT shells without adding much weight. That’s it.
The requirements asked for protection against the 90mm HEAT from all angles, and the 122mm AP at 950 m/s on the hull (±45°) and turret (±90°).
The “nuclear war tank” idea comes from the NBC protection and the four tracks, which gave it better mobility in mud and snow than other tanks (think of the terrain after a nuclear blast in winter).
The PAZ system did protect the crew from a blast wave, that’s in the requirements, but it worked by sealing the tank: it closed the hatches, vents and gun openings and pressurized the inside with filtered air. It had nothing to do with stopping the tank from tipping over, as some people think. And the idea that the hull shape was designed for the shockwave is a myth too. So I wouldn’t trust Gaijin’s wiki on this.
My sources: “Tekhnika i Vooruzhenie” N°6/2015, N°12/2017 and N°1/2018.
To a lesser extent, the same thing used to occur with the Merkava’s M339 HE shell, and to fix it, Gaijin removed its SAP performance. That made M339 unrealistic as well, since it is functionally a SAP shell IRL.
You can’t do this with HE, not even with 11 kg of TNT.
In the end, SAP shells in the game have some weird characteristics that make them overperform, like APBC shells, which somehow work better against sloped armor than other full-caliber AP shells.
The best explanation I have is that SAPHE, with very good high explosive filler, penetrates the track and then explodes underneath / beside these vehicles, where armour is very weak. HE cannot penetrate most tracks in this game without activating its fuze.
But I don’t really have a good explanation as to why some vehicles (that don’t have weak side armour / weak floor armour) still get one-shot.
