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...

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

yes it'soriginal page from report that @Molota_477 redraw. 

Regarding weight reduction:

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

btw, this APFSDS displayed at WTD91, i think this is 105mm APFSDS for smoothbore(or early design of 120mm DM13, look at fins)
 
i think @SH_MM even posted patent for this APFSDS some time ago

T-62 with Schotte Nr.1 and Nr.2 vs 64mm HL(Standsprengung) 
 
Standsprengung some test SC ? 
 
Hull front have Schotte Nr.1 spaced at 80mm from it
Hull side have  Schotte Nr.2 spaced at 580mm from it

maybe somebody have info about 64mm SC penetration ?  based on Panzerfaust Lanze grenade ?
