Unlike the Soviet T-64A (its main rival), the KPz-70 does not utilize composite armour, but an air gap that forces munitions penetrating the initial layers to lose their mass by fragmenting apart before moving to the next layer of armour. However, this doesn't change the need to utilize what mobility the vehicle has - it's the best weapon the KPz-70 has. This unfortunately negates many of the advantages the KPz-70 maintained during its reign as a top-rank vehicle. The KPz-70 displays impressive mobility, in terms of its ability to pickup and maintain speed over various terrains - albeit it is somewhat lacklustre compared to some of the top rank vehicles such as the M1 Abrams and T-80B. It was introduced in Update 1.71 'New E.R.A.'. The KPz-70 is a rank VI German medium tank
