I wonder how thick the belly armour is, and is it reactive? Drones with vertically-oriented shaped charges and fly them under the nose or the tail.
Presumably the turret extension is built to separate from the turret if a satchel charge or a missile should happen to find its way between the turret and the top plates. Otherwise the effect is going to be like a bottle-opener.
At 6:53 you can see the gun bounce off its depression stops; the trade off for a low profile.
A fourth crewman just to fly drones? That tells us plenty. One has to wonder about the return on investment, and more importantly, what are the infantry riding in?
So far only the Israelis(?) seem to have come up with a logical answer to that question with the Achzarit.
2022 and same old tracks and no less vulnerable than they were in 1942. Tanks are more and more expensive and mines are cheap as ever.
Debatable whether something like the SwedishS "tank" is not a better investment over all. Of course the Soviets used to pretend they'd lost interest in SPG's after WWII and maybe the Germans are doing so now? After all, they were pioneers in that field.
