From the website:
Using a low level of DNA enhancement through their Rift-tech programme, the Soviet Union has created an all-female, propaganda-driven elite unit. Combined with intensive training and indoctrination, the unit has proven highly effective in combat, although it is only used when causalities are anticipated to be minimal. Their battlefield successes may well see them deployed in broader roles as the war progresses.
Combing the agility of an infantryman with the armour and firepower of a heavily built armoured car, the Spinne (spider) is almost the perfect recce vehicle for close terrain and urban environment.
