T80U with a shell that penetrates right 500 mm of armor was able to penetrate the turret cheek of a Abrams M1A2 that according to war thunder stats 40 mm of rolled armor along with 800mm of composite armor and a plate of 100 mm of rolled armor which adds up to over 900mm . The 3bm46 shell pens 531mm . How does this happen .What I’m I missing ? American tank armor is weaker then the posted value or he just had a special shell I don’t know about ? Or did I just read the numbers wrong , maybe it’s 8oo micrometers .Why do American tank under perform even though there numbers are pretty good ?
800mm of composite does not equal 800mm of armour protection

then what does it equal ???
I would assume same protection or similar protection values to Kontact-5, can hold a lot of kinetic-energy weapons but it’s specialized in chemical-energy weapons, NERA stands for Non-explorise reactive armor, in the case of the Abrams the 800mm offered only affects HEAT ammunition, regarding the exact kinetic-energy protection (e.g., APDS-FS) isn’t exact.

when they measure armor on tanks they give the armor thickness 100mm and the equivalent armor with the angle included 150mm for example . Why not the same with the composite armor ? 800 mm of composite armor equivalent to 5 mm of armor. For example .
This post was flagged by the community and is temporarily hidden.
if they don’t know ,then until the know different let it be 800mm
That over 900mm armor is under perfect conditions. Its like turn time, or max speed, where it doesn’t account for any factors you might experience in game. Furthermore, the composite armor is extruded back from the front cheek plate. If he hit you from an angle, he might have been able to slice through part of it. Could you send screenshots of the killshot?
Composite will not hold up as well vs kenetic ammo compared to RHA.
If you go to the armor viewer and test a round, it tells you the amount of the RHA that it is equal to.
If you want to see the equivalent kinetic protection go into protection analysis and pick your favourite apfsds and point it at the turret calling it “russian bs” is completely uncalled for and pointless

For example… what?
Could you provide an example?
Follow up question for op.
How do you have 113k matches and dont know this? You have thousands of games in tanks with composite armor.

i know it happens but i don’t see how !!! the number of matches i have played doesn’t change the fact my 900 mm of armor is getting penned by a shell with 500mm of pen capability. and that is after I shot him
500mm penetration will be of RHA - Rolled Homogeneous Armour - ie hardened steel, which is the default material used to measure penetration.
“Composite” =/= RHA - various types of composite armour have modifiers vs kinetic and chemical (ie HEAT) ammo:
So 800mm of composite armour may only be worth as little as 80mm of RHA vs kinetic ammo (APFSDS for example) - which would mean your 40+800+100 is actually 40+80+100 = only 220, and easily penetrated by something with 500mm pen of RHA.

Your math isn’t mathing.
I will agree that turret cheeks for most tanks are weirdly easy to penetrate. I’d imagine most modern turret cheeks are basically immune to the APFSDS we have in-game.
Whose math? Mine?
By all means show better math… just claiming it is wrong is not an actual argument.
You can use the protection analysis to check KE/Chem protection. M1A2 is about 730mm against KE in perfect conditions, but if they have an angle where they can hit it flat on it drops to about 500mm that has a chance to be penned by 3BM46.
No, the OP.
I thought you meant 13K or something but no, OP has ONE HUNDRED AND THREE THOUSAND MATCHES. Holy.

To add, in Realistic battles alone OP has spent 18,000 hours, which translates to TWO ENTIRE YEARS worth of time, of which he has spent 1.25 years in a tank. He is also 1st on the leaderboard for ground spawns and deaths.
