Regarding wedge armor,Regarding optics/TI:
No, they are not. But the Laser is the same as it comes licensed produced from hughes IIRC.
There are several optics and thermals available and in service for the Leopard. The German Leopard II from A5 onwards have a 12x daylight channel as well as a 2nd generation TI-channel wuth 4x and 12x magnification.
The TI of the new PERI-R17A2 is a 3rd generation TI (4x, 12x, 24x).
The Spanish Leopard IIE for example have a 3rd gen TI for both gunner and commander and also allow for different magnifications of the daylight and TI channels and are comparable to what is fielded with the M1A2SEP.
Regarding wedge armor:
Swerve is partially right with it's explanation of how the armor works.
Modern rounds don't get deflected even when they are hitting at an extreme angle.
There are pictures of rounds having entered the gun tube of tanks at extreme angle as well as scratching the top turrets of T-72s without getting deflected.
The KWS II add-on armor of the Leopard II is not a solid block. This would be much to heavy. Instead it consists of several layers of solid plates arranged at different angles with some space between them. This arrangement is supported by some other capabilities of the armor about which we won't discuss here.
A KE penetrator rod hitting the add-on armor is under immense pressure by the different angeld plates. This results in it hitting the main armor at a bad angle and so highly reduces the penetration capability of the rod. Depending on the round fired as well as the angle of impact the rod may also get blunted or brakes apart reducing penetration even further.
So instead of deflecting the round (which as I said modern rounds don't do anyways) the add-on armor "sucks in" the rod in order to break it apart.
Now I do not know if it will suck in all KE penetrators and break them apart, but it sure in the hell does a good job of slowing the majority of them down to make the primary armor effective in stopping them entirely.
Which brings up another point, are the Russians worried about their reactive armor packages with the latest generation KE projectiles that very well could come equipped with one heck of a composite outer linning, it already is in use due to the length of the rods to help with flight improvements.:unknown
