@Waylander,
The protection level on the T-14 actually appears impressive. The active protection system seems to be designed to protect the spot where the turret meets the chassis - the classic weak point. You've got a turret that seems to be able to survive a high-threat environment i.e. multiple RPG salvos, remote weapon system. Even if the T-14 suffers a weapon system kill, the crew should theoretically be able to survive the battle, drive back to the maintenance depot in one piece and live to fight another day - with a new turret.
Also, I need some help understanding the 'optic on the roof.' Is this the equivalent of the L2's commander sight? If that is correct, in the case of the T-14, wouldn't the 'optic on the roof' be the sighting system installed as part of the remote weapon station? (Feanor refers to this as panoramic sight)
Assuming both commander and gunner have shared sights, I think the T-14 has a basic ability to 'drive forward from cover and say hello'.
By the way, regarding the coax, the slot doesn't seem right - I could be wrong, but it doesn't seem to allow the same angles of elevation that the main gun can achieve. The slot may have another function i.e. air intake for cooling some of the systems? I'm really just guessing here...
@Feanor,
Are there any safeguards on the T-14 to prevent the remote weapon system MG from shooting off the active protection system sensor/antenna? Sorry...I know it sounds stupid...but hey, you only learn if you ask right?
Also, it seems like the Armata, the Kuragnets, Bumerang...despite have two different turret configurations, the turrets seem optimised for urban operations i.e. high angle of elevation.
Do both types of turrets have active protection system? Any idea why there are two turret designs instead of a single one?
Sorry guys, I asked a lot of questions...long day for me, had to get all the questions out of my mind before I can sleep peacefully
