An unmanned turret with an auto-loading ammunition system makes possible a reduced crew size, down from four to three. This is also a major draw, increasing survivability and freeing up space in the turret for more capabilities.

The Soviets went to autoloaders and 3-man crews 50 years ago. Part of why we didn't do the same is reducing the size of the crew isn't that great an advantage on a 67-ton machine that requires a lot of field maintenance.

Auto loaders are mechanically cranky and, as we see now in Ukraine, require rounds to be stored in the turret, causing catastrophic detonation that kills the crew. So you save 1 to kill 3.

In this, the turret is unmanned, and I assume it would blow off if there were a detonation.

I guess the remaining crew are in the chassis somewhere with video links providing guidance to the gunner and commander.

No way to see if those are disabled I suspect, and the optic mounts look very vulnerable. A larger number of embedded cameras with the video merged like bug eyes would be preferable, so one or more can be disabled or obscured but still get a full field of view.

Arguably, the designers anticipate that by providing for the new tank to have reduced maintenance needs. There is a broad trend in US military designs to that effect.
