The most important are not the engines or speed or whatever. KE has to have a titanium monoblock structure to overcome those manoeuvres and G shocks. Otherwise, it can tear apart like a piece of glass.
I think after TF-2000, we will need a class between TF-2000 and Istif class which it will attack/saturate the deep land areas to dominate the enemy soils.
