I did a lot of searching and the Abramx x at this point still born, but that could change.
One site said compared to the Armada the X was lighter, manuervable etc., etc. but could not take the punishment of the Armada or current Abrams.
We really don't know that much about the Armada do we? At least not beyond what the Russians
claim it can do.
The AbramsX did get into the separation of the ammo from the crew, by way of automatic loader, placing the entire crew in the hull.
Some of the Russian tanks have that feature, but their automatic loaders were erratic in function..which in itself
certainly endangers the crew. I doubt our designers/engineers would take that same chance.
The Abrams does have ammo storage separate from the crew, but in a different way.
https://www.inetres.com/gp/military/cv/tank/M1.html The tanks I served in back in the 1950s, had our main gun ammo stored vertically around the periphery of the turret, and horizontally under the turret floor.
Many of the Russian tanks in service today, still store ammo in that way, which is why, when the ammo "cooks off"..it blows the turret straight up off the tank..
