This was copied from Leopard2. The Germans were certainly no amateurs & they still haven't changed it!.. I have a theory about this.
And it's not just the issue of the positioning of the gunner's sight, there are other more troubling issues as well. For example,
a. The turret is significantly wider as compared to that of Leo 2,
b. The armor behind the gunner's sight has also been proven to be thinner from available photographs of the turret interior as that section does not extend farther backward to compensate for the room taken up by the sight a is the case in Leo 2s,
c. The mantlet appears to be wider as well and hence it leaves a larger section in the front vulnerable and the list just goes on.
No big deal really!! Just place the gunner's sight on a raised platform atop the roof (just like we were discussing raising the section above the main gun) and have it tilting a few degrees forward!! Or alternatively, place it on a raisable must like what has been done with the NAMICA.View attachment 59934
The magenta line is -15° representing max possible gun depression. Only if the gunner-sight is placed on the front can it look down at such angle (blue). If it were on the top it would only be able to look down -10° (green)... Now that the design issue exists they might as well make the most of it!
Nothing to disagree there, depression is good. We don't need a happy tank, we need a sad one!! Lolzz.At that angle, standing in a dip in ground or against a ridge, not only very little of it will be visible but any penetration would actually go out of the roof.
Not just the ones you named but it's true for virtually every modern MBT there is. In earlier times, the mantlet used to be the most heavily protected section of a tank, now the turret cheeks have taken up that place.I'm not sure why nobody cares about the gun-mantle though. Leopard, Leclerc, even T-90 has the centre of silhouette left thin.
Apart from the upper left section and that huge lower glacis plate (much bigger than that of the T-XX). The only saving grace is that there is a large fuel tank with armored bulkheads right behind the glacis and the hull ammo stowage getting compartmentalized and fitted with blow-off panels. That's an improvement over the Leo 2 and most other modern MBTs with hull ammo stowage.Otherwise not that much of weak spots compared to T-XX.
