Sidorov Proving Grounds

(January 2nd, 1944: Alternate WW2) With the Soviets inbound for Berlin and the collapse of Japanese China, the Soviet forces are innovating for the end of the war with new tanks that will change the rules of war forever. The Sidorov Proving Ground is a secluded area a few kilometers off of Moscow, designed to be hidden from enemies while being as big as possible. This is an area where infantry, tankers, and even pilots test their skills and train for the war and after the war.
