My article in english version Frag Out! Magazine:
https://fragout.uberflip.com/i/1150145-frag-out-magazine-25/69?
 
This time about Panzerfaust 3 and RGW90 familiy. For user here may be interesting part about PzF-3T/IT test in Poland vs ERA.
 
 

Coming back to the old German specification for armour steel (TL 2350-0001): The allocation to hardness is the following
A, R and D   250 to 300
B                   310 to 360
C                   340 to 390
E                   400 to 450
X                   370 to 420
W                  400 to 450
V                   440 to 490
L                    250 to 300
Now @Wiedzmin you can perform the analysis for the old Leopard 2 AV.

This time, photo taken by myself.

single 81mm in 1st salvo:

 
 
and single 81mm in 2th salvo:

 
 
And this one was mucht difficult due to weather conditions.
 
Six 120mm motar round on one picture:

 
And twins:

 
 
And the result:

 
 
 
 
In summary - 120mm SMK Rak is very good weapons, very powerfull modern and now the best serial produce in the world. Nice that at least one type of weapons producing in my country can be on top lvl...

Today our PM signiture contract for upgrade up to 318 T-72M1.
https://www.premier.gov.pl/wydarzenia/aktualnosci/premier-mateusz-morawiecki-odbudowujemy-potencjal-polskiej-armii.html

 
Firstly, it will be upgraded between 250 and 318 tanks. It depends on how much money from this PLN 1.75 billion will be spent during program.
Secondly, the range of work on tanks will be different - some T-72M1 wil get more mork other less,. It's  due to fact that some of them have been rebuild since 2014 so it's not neccary to rebuild all tanks.
Thirdly, "small modernization"  includes: 
-  PNK-55/72 „Radomka” for driver
- Liswarta (or TKN-3Z) for Tc
- new fast hoping ECCM radio  RRC 9310AP "Radmor" (in comander tank - two radios)
 - full seto of PCT-72 thermal sight for T-72 tanks  including KLW-1 thermal cameras and two monitors - one for Tk and one for gunner.
And thats all...very budget rebuild whit cosmetic "upgrade". 
 
About PNK-72, Liswarta and PCT72 you can find data here:
https://pcosa.com.pl/wp-content/uploads/2018/07/PCO_product_catalogue.pdf
pages 18 -21

Penetration at "normal" means perpendicular impact angle to the armor plate, so the 85° impact angle makes sense. The gun was probably placed a bit too far to the side, thus it didn't hit the turret front at a perpendicular angle (i.e. 90°). I believe the impact angle written next to the HOT impact on the left-hand turret side is also supposed to say "85°", it is just hardly readable due to poor hand writing.
 
The fact that the turret armor was penetrated by the DM23 isn't surprising, given the impact location and the limited LOS there (orange line):

 
Overall protection seems quite good. The gunner's sight weakspot was penetrated, but only barely so that a spall liner (or maybe the electronics of the gunner) would have stopped the residual penetration, crew would stay alive. Hull seems to be worse, but again all penetrations are "unlucky". Shot 5 (KE round at hull front) split the weldline, so it seems it hit the edge of the hull armor module rather than the center. Shot 6 (KE round at left-hand hull side) missed the armor skirt. So only one penetration by HOT (shot 1) seems to be "normal"/"fair".

1974 requirements
-105mm KE
-120mm KE
-120mm HEAT

120mm HEAT penetration, and there is a first problem did they tested Leopard-2 with real shots and built in stand-off or they used static tests with Optimum stand-off, because protection could be 480-500(btw my bad, not Meppen test, some RARDE reports), or up to 700
 
1977-78 requirements

did they dropeed idea of protection from 120mm KE, or just not mentioned it in report, also Milan, penetration of Milan at built in stand-off 530-560mm

 
mean crater profiles, it's not pen, but depth of jet inside target, pen little bit less, so again, did they have protection from Milan in 1974 or they updated in only after 74(76 maybe? or even 77-78) did they fired it on tank, or used static with optimum stand off ?
 

 
1987 requirements(one of british reports claim that germans will start placing D-tech packages in 1987-88)
 
-120mm DM23
- HOT


and once again
 

 
HOT mean crater profiles, so if they tested Leo2 in 1974 and 77 with optimum stand-off(710mm pen) then 1987 "improvement" look silly in terms of CE protection (710mm 1974-1978 up to 750-780 in 1987), but if they have only 480-550 in 1974-1978, there is a great increase in CE protection level, or they were "ok" with CE level, but want improvement in KE + some little "update" for CE.
 
as for "abandoned bulging armour" i think they just mixed it with ceramic to get protection against CE, if they ever really used ceramics inside Leo2, because germans still can't produce good enough ceramic plates(Al2O3 plates IRRC) for body armour, and i'm seriously doubt that they can produce good quality ceramic for use in tank CE protection, it's expensive, it's not durable, and you need to have some very good quality check for it, or they just used some chip "dirt" like in T-64 turret, it doesn't need to be "super high tech" if it's work.
 
british claims that this report also contain about "Leo-2 protects only vs old steel soviet APFSDS" is BS, this is clearly seen in the 1974 report, germans have WHA long rods requirements from the start, and this requirements was stronger than US 105mm APFSDS, and i think more or less similar to british requirements for CR1 with XL23(IIRC, yes it's monoblock APFSDS, but shitty alloy and round), as for "low numbers" or "lol it's level of T-64" without knowing real estimation procedures you can't compare "300 vs APFSDS german" vs "300mm vs APDS/APFSDS soviet", again, for example we have T-72M1 with 16mm addon, which gives 405mm vs M111 APFSDS, does it mean that T-72M1 have better armour than Leopard-2 or...
 
for understand what is real level of protection you need to test all tanks with similar rounds in similar conditions 
 
 
firing trials of 2AV and full armour scheme i will upload later...

My article in english about Carl Gustaf and NLAW - hope it will be interesting:
https://fragout.uberflip.com/i/1115818-frag-out-magazine-24/47?

In the end of the article is interesting part about polish RPG-7 uses, stock nubers and...mobilisation numbers

Regarding weight reduction:

no, tank with EMES15 need to reduce it's weight by 1789kg to get in MLC
 
@SH_MM thank you

1976  Leopard 2AV armour(all from declassified reports), bustle spaced armour(12+30) also used on serial Leopard-2 tanks.

here what Leopard-2AV(and i think 2A0/4) mantlet armour look like in 1976 soon i will upload sort of "article" about Leo2 armour from 1974 up to 1987...
 

weight of this one - 670+38 kg

.  This tank was restored more then decade(!) and it was taken from Truk lagoon.
And it's wonderfull restoration -even tehnical description in japaneese are present in tank. The engine is like orginal but based on post IIWW ones whit orginal Bosh eqipment.
To be onest -it's the best restoration I'v ever seen. It's greata. Milions of $$ and a lot of time to achive sucht result. Amazing!
This tank will be in Bovington Tank Museum not in Poland. Tank belong to MV collector from UK

T.95 Ha-Go, restored in Poland. Awesome!
Quite nimble little beast, with great sounding engine. (driving at the end of the video)
 

Yes, it's beyond normal level of stupidy...
 
Polish army start program "Otokar-Brzezina" (named as famous general) for rocket tracked tank destroyer.
And pretend will be:
1) Hellfire luncher (DAGR or this from Stryker MSL) on K9 chassis (so polish Krab SPG chassis)
2) BMP-1 (lol) chassis whit Brigstone lunher
3) something whit Spike LR luncher.
