I think this may be catalogued as a medium tank or a new class entirely. We´ve seen prototypes with extra armor (and not just extra side ERA, even the hatches were different) and 3 gun options so far. So this is what I´m thinking: this is a 2 man, low base weight "lego tank". With firepower, protection and mobility tayloreable depending on mission needs.Are we sure this is MBT class? It looks light-ish to me.
