The Play Testing has now ended.
This has resulted in the following:
"From the moment that Germany, Japan or Italy declares War on - or attacks the Soviet Union, the Soviet player receives 1 Tank unit in each round, to be placed in Urals.
The Soviet player must control Urals from the start of the Soviet players turn in order to receive this Tank unit.
If Germany, Japan or Italy are not at War with the Soviet Union by Early 1941, the Soviet player receives this Tank unit from the start of the Soviet players turn in Early 1941.
Other rules concerning this Soviet Tank unit are still according to the rules described at page 13.
This rule will be part of the updated Axis & Allies Global 1940 House Rules Expansion (expected release Summer/Autumn 2022).
