8.56 mm Gebauer 1939.M MG - 20mm penetration?

I don’t have any source, so I can’t submit a bug report. Is this really true?

Also, isn’t the caliber 8mm instead of “8.56mm”? Could this be a typo for “8x56mmR”?

Even IF its some magic HVAP round (with rather low velocity) gaijin stated some time ago that all MGs below 12,7mm get an unified penetration of 13mm.
So i am certain its wrong. Not to mention the AP-T (iirc) has 13mm, but also the cannon shrapnell preset (see the big ammo picture instead of rifle one in protection analasys and modification window) resulting in a cone of shrapnel upon penetration making it really strong against light armored ground targets.

So no, both are wrong.
My guess is, its a typo for the 13 → 23mm.

Is this what you mean?
Indeed, other 7-8mm caliber bullets didn’t scatter like this; they simply penetrated cleanly.

Hopefully it gets fixed during the DEV phase…

Yes. In general thats only for cannons.

War Thunder is not accurate to their terms and naming, so there are a lot of vehicles name with wrong or missing designations.


Not at all, at least not for ground vehicles. Schützenpanzer PUMA’s 5.56 mm MG4 Ball-tracer ammo is limited to 5 mm of penetration at 0 meters.

I meant for AP ammo. Ap-I and AP-T 9mm (depending on penetrator size) and ball and T ammo 5mm.

wikipedia isnt a useful source for this.

Sure. So if anyone has the exact source, I’d like them to submit it here.

you do know there were Thngsten core AP(C) rounds in 7.92mm which have a much higher Penetration than most Steel penetrator Rifle caliber rounds

a Blanket penetration value would generally be no good

Yes, i even suggested them for the Coax Mg 34 and 42 in game.
Yes i know its stoopid, IRL the 7,92mm S.m.K had 14mm penetration.
And no, this round isnt an HVAP round, not to mention the rather low velocity of just 730m/s (if it were HVAP), the S.m.K. H had 875m/s.





Upon closer inspection, it seems all the newly added Hungarian 8mm machine guns use the same ammunition data.

I don’t have a source, but should I submit a report…?

Yes, why not.

I’ve prepared a report for now.
Since there’s no source material, I’m not sure if it will be approved.

approved with no source? how come?

I don’t know.
Perhaps the moderator had the source.

Fun fact is, Gaijin has no source either.

F.e. T-34E with 15mm applique on the hull even when angled gets absolutely roflstomped by 85mm cannon as penetration through each plate gets calculated separately, so 15mm gets super overmatched and treated like it’s not angled at all, as a result entire array behaves more like 49mm plate at 60 degrees.
Of course this is absolute BS and IRL 15+45mm array is almost as good as 60mm plate.
But you can’t prove it wrong, as there exist no study disproving the “fact” Gaijin 100% made up.

So basically the reason this report got approves is because Gaijin doesn’t want it to have 20mm penetration, as they do not care about physics anyway.

Hi, yes the 8.56 mm calibre is complete BS. It is an 8 mm machine gun, the mistake likely came from it being chambered in 8x56R. The rate of fire should be 2000 rpm as well (instead of 1800). Btw, I wrote that section of the wikipedia, and here’s the source it’s from: https://epa.oszk.hu/00000/00018/00289/pdf/EPA00018_hadtortenelmi_2012_03_677-716.pdf (in Hungarian, pages 32, 33, and the table on 35 are relevant)

The pen and explosion of the rifle cal MGs are certainly wrong, but you’ve done the bug report on that.

The names are also horribly wrong for the MGs on the WM-21 Sólyom:
-The forward firing “8 mm Gebauer Gebauer 1926/39.M” is supposed to be 8 (or 7.92?) mm Gebauer 1926/31.M (so the name, model year, and potentially calibre are all wrong lol)
-The defensive “8 mm Gebauer Gebauer 1934/37.M” is supposed to be 7.92 mm Gebauer 1934/37.M (wrong calibre and name, but model year seems to be correct)

The front MGs on the WM-21 also might be 1330 rpm instead of 1300.
The 8 mm Gebauer 1939.M MGs on the WM-23 also might be 18.2 kg instead of 16 kg.

Also, the 40 mm gun on the Me 210 Ca-1 39M… well in the name of the plane it is referred to as “39M” (correct convention) but in the name of the gun itself they call it the “M39” (wrong convention)… I believe it is actually a 36.M gun (not 39).

The naming for all the Hungarian guns, engines, names, etc. are done really lazily, as though they asked the worst AI language model for historical details. They would honestly have more success just blindly trusting how they are written on wikipedia.

Edit: I created a bug report for the calibre of the 1939.M: Community Bug Reporting System
I have not created bug reports for the rest, because I’m not an experienced bug-reporter and don’t think I have good enough sources, and am not 100% certain on the exact stats, so I’ll leave the rest for people who know what they’re doing.

A major update has been released.


???
Is this a Ball bullet or something?

well, people here reported it without a source so Gaijin just put it there without a source

no way to correct it now
