I can explain a lot here ;-)
3BM31 and 3BK31M was attempd to incarase penetration in HEAT round without changing working method of cumulative warhed. Now in west we have SC whit 10-12 and even mor CD penetration. In the end of the 80's it was impossible so choosen operation method was diffrend.
Precursor in BK31M is just normal  precursor - nothing to do here exept that in some sources this precursor have abilitiest to work like in HOT3/PARS so beeing lunched in to target before main round part had optimum stand-off distance. In  other - just slinding to have bigger distance.
Main charge - here is funny - axuilary cone (second charge) was to just incarase armour penetration. This SC was ignit first and milisecond after ignit was first (main) SC - two jets where joined together and become one long "super jet". Wery sophisticated idea but dead end.

Well known APC Rosomak in Afgan. version armour:
 

 
Orginally it was israeli but after that it was produced by polish company "Mikanit":
http://www.mikanit.com.pl/produkty/oslony-balistyczne.html
 
Now, we know patent draws and description:
 

 

 
 
Composition:
2 mm HHS + air + 6,7 mm HHS + 5 mm composite + 5 mm composite + 5 mm composite + 3,5 mm HHS + 35 mm air gap + 3,5 mm HHS + 5 mm composite + 5 mm composite + 3,5 mm HHS + 35 mm air gap  + 20 mm aluminium + 5 mm aluminium.
There is possibility that layout could be 4+3 (composite) and single composite layer can have up to 6mm thick and single HHS layer can have  4mm thickness. Layers can be separate up to 45mm.
 
Accoding to manufacurer this armour can protect against ATGM and RPG's up to 500mm RHA penetration.
 
Whole armour is combat proven in Afganistan - there are known some "Rosomak" whit 3x RPG's hits diretly in to this armour - no penetration at all, no engine damage. 
 
 
 
 
 

Germans few yers ago had shown poles (and not only) abilities AMAP-ADS to stop DM63 from <200m distance.
The target was empty Leopard-2A4 hull and turret (only whit armour + ADS). There was sevral shoots from 120mm DM-63.
No perforation, the deepest mark from rebound long-rod have circa 50-80mm deep (mesured by hand for one polish officer there so inacurrate).
Anyway - ADS is able to stop long-rod even whit Vmuzzel = 1700m/s

Orginally polish second generation 120mm APFSDS-T ammo:
 

WBG-X in 2A4 and dozen of targets - BMP-2, M113, T-72M1, M2,  etc:

Orginally polish second generation 120mm APFSDS-T ammo:
 

@Methos
 
 
Im not sure if Fovanow is living in empty space Who really know usally don't wrote anythink... The true is that 3BM48 is placed in offcial KB Tula statsment as DOI in 1991:
(source from circa 2010's (previous decade)

Год  принятия  на   вооружение - DOI
Существующие  образцы - existing amunition
Находящиеся   в   разработке - In development
Планируемые   к разработке - Planned to develop
 
And it's present in FCS contol pannel in Sprut-SD:

 
 
And it have GRAU designation.
 
And yes - whole BM9, 15, 22 etc are still using in Russian Army as in Polsih army - what is stupid - mostly for trening purpose, couse APFSDS-T-TP is not ussaly avaible...the same think is in Polish and Russian army unfortunatly. What more - polish PT-91 are still using 3BM15... And Russian tanks - 3BM26
 
 
 
Wikipedia is not a source. Read english wiki about Leopard-2 tanks and You will see why.
 
 
 
Answer is very simple - Sowiet and Russian DOI is before amunition is mass placed in tanks.
3BM32 was developed in 1985 but DOI and 1987 and  introduced in mass production in circa 1988-1989 3BM42 was developed in 1986 but DOI in 1988 and introduced in mass production in 1989-1990, 3MB48 was DOI in 1991 and introducen in mass prduction - well good question if or in what number At least Sprut-SD have it in FCS.
Svieniets-1 and 2 was developed in end 1990s and  DOI in 2002 but propably indeed mass production was redy in 2010 - or even later. So there is no discrepancy here. Offcial DOI in to service and give GRAU designaton is few (or even more) years before mass  production.

Some APFSDS marks on destroyed tanks:
 
T-72M ODS 1991:
 


 
 
Separatist T-72B m.1989:


(the most strange think is that this tank not blow out after sucht hit..)
 
 
UA Army T-64 BW after hit:


 
 
well known separatist T-64BW destroyed by two APFSDS hit:


 
 
Iraqi T-62 2003 OIF:
 
1st example:

 
2th example:

 
Russian/separatist T-72BW after friendly fire to destroy damage tank:

what is interesting - fist shoot was on sucht short distance that we can see sabot mark on plate -so distance was under 50m... interesting. 
About fins marks - 3BM42 in action?

Leopard 2(A0/A1) Study Update:
 

You are unlucky - in Wroclaw city where I live there is big LG corp factory whit many Korean Managers. And preatty close there is TAKATA and Toyota big factories.
Funny I know people who know both - Korean and Japaneese language. And I had ask them about this whit kindly ask for translate.
It cost me a lunch. 
 
And it's not about tank but indeed lenses. 
 
You are fucked in the ass misarable piece of shit who misinforms peoples here. Honestly - go to fuck yourself, and as many as it's possible dicks in to ass of you, your family and dog or other pet you have.
GTFO!!!

Waffentrager YOU FAKE BULLSXXT and FXXK OFF

In case you guys here cannot read Japanese:
It says "Height of lens assembly is about 380 mm"
May be taken from a manual of digital camera or sth. else. 
 
 

So which one is it, do you have the full document or not?
 

Considering this was posted by someone new, I had it checked with a translator I know. And yes, this is about cameras, not tanks.
 
Also you can say bullshit and fuck on this forum, welcome to the club.

Sweet but I had mesured it on REAL Leopard 2A4:

BTW - front hull was 600-620mm thick but I have not photo couse pissed off sergant (military woman...) almoust shoot me down for making sucht photos whit measure tape
And text  "back to the kitchen" wasn't the best idea to be honest...
 
btw2 -inner masuremend to find where is backplate and how thick it is:

Yes, it was planned to give GLATGM for next generation tanks. But no details about missailes and no even codenames. Just info about work on cal.152mm GLATGM.

Guys, this draw is FUCKEN FAKE
Photoshoped by WoT gamers from Russia.
Ok, respect for sucht fake but anyway -it's fake and bullshit.
So sad, but no -we know nothing sure still.

EDIT:
 
This 125mm ammo -it's US "black project" of 125mm test APFSDS whit technology of the XM829E1/E2 -so evaluation how good can by Sowiet APFSDS based on build "US 125mm ammo" on best avaibla components. It was XM.... (i will find this marks in my notes and put here).
 
 

 
 

@Methos
Confirm that german special amrmour was not tested in USA:
https://babel.hathitrust.org/cgi/pt?id=msu.31293016483954;view=1up;seq=1
 
marevelous document about 105mm vs 120mm in USA:
https://babel.hathitrust.org/cgi/pt?id=uc1.31210024740399;view=1up;seq=1
"we know that 105mm is shit but it's cost effective"
 
BTW: Im agree that Leopard 2 is understimeted a lot. IMHO whole think is taken from T14 turret values or fact tahat in Leopard 2AV tehere was no special armour - just "cavity" made by frontplate and backplate - X-rayed by Americans who "discover" there is no special armour there. So propably (it's only my assumption) value for Leo2 is taken from XM1 whit thinner backplate and frontplate in leo-2 (2x 45mm RHA)
IMHO there is no other logical explanation of sucht value
