Wiedzmin

made better pic, 85-110mm estimate is a bit overestimation, but...

lower plate also could be welded "box" and not simple RHA plate

also possible that upper part of mantlet is simple steel( two) plates) with addons on it, but due to museum have prototype vehicle, maybe something different used on serial vehicle...

and mantlet is a...thin...

with all of that "tons of "armour"" frontal part doesn't look thick, and mantlet protection module is a .... 150-160mm max at 73-72 deg which gives 550mm LOS max with mantlet + trunnion block behind it 

what was idea(i understand that it need ribs for strength) behind Leopard 2 belly bended inward(and weld shut concave areas with additional plates) and not outward like on T-series and use those bended areas as place for torsion bars ?

Another view of “That Tube”... that matches this, 

tube used for failed ammo round IIRC, to not throw it to the ground where "someone" could pick it

mk3 welded turret 

and casted

and engine bay "armor" wall

This confirms that the side hull module has explosive contents. It reads "נָפִיץ" ("explosive") there. 

as far as google translate - yes 1972

made very rough model(only for understanding how geometry of detail look like IRL) of Mk4 frontal turret parts, right "wall" have trunnion resolver or something like that in "big hole"

well first plate is steel, and there must be K-5 inside

Arjun sides, emm... textolite ?

Mk3 welded variant ?

Mk4 

AMX-30, possibly 

it's not... it's T-55M8A2 Tifon turret on T-64 hull

115mm 3BM21M....maybe

in between the armor should be accounted for as well.

nope

And in addition we have very thick turret walls

lol what ?

sides 50-60mm MAX, thats why side modules are so thick, to get any protection for this "anti-rain" base protection

gun embrassure assembly 250-300 in thickest part, and thats all, pretty weak turret 

and frontal modules is much thinner than side, and with 90% chance have same concept as previous Mk's - KE protection with steel at frontal part + NERA pack, and NERA only on sides 

\

and if this is a frontal parts, than it's even less thickness 

in the end Mk.4 is just a attemp to get rid of Mk3 chaotic construction, more uniform protection with less weakned zones, but basic concept is a bit stupid, so you get what you get...

you get length of module, not LOS.

LOS of 1.050 m length module will be not very high, if thickness of wedge is 300mm you get 877 LOS, if 200mm you get 585 mm LOS, real thickness could be even less,
