Dazzler ,dude,you really think that you're adding something new here??Do you really believe I'm not aware of the GMS (gunner's main sight) placement issue??
Listen man,there is NO COMPOSITE armor behind the GMS,instead DRDO has placed a ~460mm thick solid block of hardened heavy metal alloy with a TE (thickness efficiency) of 1.6 - meaning a 10 cm thick plate of that material has same ballistic resistance as a 16cm RHA plate has.It's more than enough to handle all current and future FSAPDS rounds in our neighbourhood.And the army would've definitely sought modification if they thought it was such big a issue as it is made out to be.
Besides,it's a very small window at the right upper corner of the turret.Good luck hitting that place at 2000 yards.
Even I could tell that AK has a partially exposed roof from front angle and its turret sides are particularly vulnerable even from frontal ark.Even worse,AK till now doesn't sport a hardened mantlet mask!!Each and every one of these are much more glaring gaps in AK's protection compared to the GMS of Arjun;but do the Indians make a big fuss all the time??No,because these have been discussed more than once before and they no longer present anything valuable........other than stupid d!ck measuring to satisfy someone's ego.So now lets give it a rest.
And yeah,110cm was plain exaggeration on Kunal's part,I told him that myself over there.But 950mm is almost correct,even Dejawolf and militarysta now somewhat agree with that figure after Kunal posted his measured pictures he took during Defexpo 14.
