Ha this is a good one.
The tanks have been modelled with the correct weights, engine power, armour, armour thickness, engine performance, gunner sight parallax (sim mode) on top of having the internal tank layouts pretty well represented. You also have the choice to drive in manual mode with clutch if I recall correctly.
In regards to aircraft I can tell you either fly with instructor or have never played Sim. In Sim a large chunk of aircraft fly exceptionally true to life with some flight models apparently even being better than DCS which for some reason many hold as the holy grail, despite the fact that War Thunder has a vastly superior damage model and as mentioned at times… flight models. Tell me how skin deep War Thunder’s FM’s are when you’ve tried taking off in an I-16 in Sim the first few times…
None of this has any real truth to it at all.
So you’re trying to explain that APHE is more skill based than AP… you know… the round that can detonate literally behind the crew and send shrapnel backwards ignoring physics to one shot your tank? The rounds that usually have very similar penetration to AP to begin with (especially in WW2 tiers) and always has more than enough to frontally penetrate everything it faces and ultimately one shot them.
APHE is broken, it’s being abused by most tanks/nations and blatantly needs fixing.
