Isn’t a ton of public info but the box ones apparently have a couple layers of plates inside and are probably more focused on typical HEAT type threats. The curved ones came about after EFPs became an issue iirc, meaning they probably are more focused towards kinetic protection. But to know anything 100% certain we need to wait a couple decades for a good book to get written once it’s declassified or hope the wrong guy gets in a war thunder argument
