Greate but you still does not understand. Imagine that you are sitting on gunner seat -yes? So you are sitting on hise seat. In front of your head you have main gunner sight vision block (marked on green) those sight have shape like a box whit protruding from it the binoculars. All has deepth more then 30cm for box + some depth for the binoculars. Above your head is those slopped orange fcs part -it's placed whit some angle (slopped) becouce your task is to use it while you are sitting on your place. So it's slopped and above your main sight vision block (green). But slopping those orange slopped FCS part means that lower edge (this closer to the green vision sight block) is on one vertical line whit front edge of this green sight, but slopping means that upper part of this "orange slopped FCS part" is above your head. After those orange FCS part you have space when on turret roof is placed those vision blokc - it's unable to see it from your seat but it's there and you are able to see some day light under lower edge those slopped orange FCS part.
You can clearly see the dark shadow of the upturned yellow plate attached to the bottom of the orange FCS block falling on the white wall of the protruding armor block in PIC No-3 Below.
You "green" main sight vision block have some depth - it's significant (more then 30cm) -and in end of that depth you have front plate of your green sightvision block and vertical placed inner backplate from armour after main sight. Above this front plate of your green sight vision block is placed those small roof placed vision block -becouse it's deepth is small (circa 5-8cm) it's on one line whit part of the green sight vision bloc and slighty before orange slopped FCS part -becouse it's slopped, there is place to put both parts in one vertical line whit green vision blokc.
If you magnify the photo you can clearly see the shadows of the electrical pipes behind the orange FCS part, If there is no extra armor block behind orange FCS , on which object is the shadow falling?
The point C is 900 mm from the Tc's seat back as per the head measurement supplied by Dejawolf on whose credentials you place so much faith. The seat back is 2500 mm from the front vertical armor plate above the gun mantel plate. SO 2500-900 mm=1600mm.
The cutaway for main sight takes 700 mm LOS thickness away.
SO 1600-700mm=900 mm. This 900 mm space only increases above the green colored Gunner's main sight block till the roof. The shadow of the electrical cables on the white inner wall of the protruding armor block is evidence to that .
Take a good look at the picture below.You have written pic-3 on the additional armor block behind the main sight.
Now explain what is the dark space(Arjun inner roof) on the right side of the armor block. And why that dark ARJUn inner roof is higher than the white armor cloumn on which you wrote pic-3.
It is on the side of the protruding inner armor block behind the Gunner's day and night Main sight a black cellphone type instrument and and a white rectangular box type blue transparent glass (optical glass) instrument is bolted.
So denying there is no additional armor block behind the main sight to compensate for the 700 mm main sight cut away is seriously wrong.
The reason is the armor block extends inward to add thickness behind the main sight. On the right side of it the frontal armor column's thickness besides the main sight alone is good enough.
You can clearly see the dark shadow of the upturned yellow plate attached to the bottom of the orange FCS block falling on the
white wall of the protruding armor block in PIC No-3 above.
If you look at the left side of the inclined orange FCS part you can see it's shadow falling on the same white armored block. And an inch to the left of this shadow you can clearly see the sharp edge of the protruding armored block
But look at the picture below the small orange plate is folded and there is shadow.The white armor wall with armor numb nuts is clearly visible . For me it is further evidence that there is around 900 mm LOS armor thickness behind the main sight.
Even if you deduct 100 odd mm for any error there still remains a substantial protection for area behind main sight.
So if you don't have any logical rebuttal for these points let us stop this debate.I too won't post any further on this matter as no more explanation is going to change anything
Neither you nor me own this thread, If you have convincing proof to the contrary post it in a dignified manner with decent choice of words.
Otherwise just leave it. I am not pushing my opinion on anybody,neither am I asking you to accept my views. I just post what I see in the picture.
LET OTHER PEOPLE POST SOMETHING USEFUL IN THIS THREAD.
