Seems that the side armor of the K2 is designed to stop 30 mm APDS (or "00 mm" APDS) along the crew compartment and 20 or 30 mm AP ("00 mm" AP) at the rest of the hull/turret.

it's also can be 20mm AP-T or 14,5mm AP-T, even 7,62mm AP need two digits thickness of armor

Leopard 3SL report if someone interested

welding over covering plate of "ceramic"  addon (which is usually thin foil), yeah...

Mk3 welded turret
 

15.2.1978, bergepanzer concpet studie, requriment was to have same as  Leo2 engine compartment and hull bottom level of protection 

Hot3 precursor

Interesting proof rounds from LMZ muzeum

Actually, giving it a closer look, I noticed the steel plate behind the gun shield is very thick so it shouldn't matter much that the shield itself and mantlet(?) is thin.

not very thick

thick sideskirts too.

nothing special, and short skirts is kinda outdated, tall ones(like on Namer) looks better

Slight asymmetry is to be expected on 3 man turrets

thats 2 left modules from 2 different turrets, not right one and left one from same tank

btw is there any good photos of V shaped holder ?

always was interested how bolts hold it

Most of it is about ERA, but there are also tests of NERA and of passive armor using ceramics (boron carbide). But IMO the biggest reveal is the usage of UHU

possible to translate ?

1976-79 german ERA trials 

some strange Leo1 based turkish vehicle 

interesting part is that modules seems to be a bit different 

maybe somebody know the source of this ?

The experience of the tests of the Leopard in Arabia showed the need to check and clean the filters 7 of the 12 days of practice in the desert, at the rate of a check every 168 km [4]. To carry out optimal maintenance of the intake system, the cyclone filters and the paper filter cartridges must be disassembled and cleaned with compressed air at less than 5 bar from the inside out. If there is even the slightest damage to the filters, they must be replaced [12]. In addition, the filter covers and the casing must be checked and cleaned (see Annex B).

-The normal operating temperature of the motor must not exceed 100ºC; The Leopard's integrated security system indicates with an alarm on the driver's panel that the temperature is exceeding 110ºC and prevents the MBT  from operating if the temperature is not reduced immediately [12].

- The engine intake system is not sufficiently protected against the high concentration of particles (sand and dust), so it could accumulate in the chamber in which it is located, damaging the systems (sand is very abrasive), occluding the ducts and clogging filters. During tests carried out in Saudi Arabia in 2011, the following problems were detected, which could not be resolved on the ground:

- With the MBT operating at more than 40 km/h, the temperature of the motor rose to 110ºC, preventing the security system from continuing its operation. Because of this, every 5 km at this speed, it was necessary to stop for 15 minutes to cool down the engine [4].
