That would be SOVIET army. How many Ukrainians were involved in the decision to invade Afghanistan? You don't want that secret out do you?
Or, what the heck. Straight from the declassified archives the following Ukrainians were on the Politburo and made the decision to invade:
Brezhnev: a lad from Dnepropetrovsk, UKRAINE.
Chernenko: while born in Russia, his father was Ukrainian - making him UKRAINIAN.
Kirilenko: Ukrainian and prior to joining the Politburo was the Ukrainian Communist Party boss in Dnepropetrovsk, UKRAINE.
Gromyko - Belarus/Ukrainian
That's a lot of oppressed Ukrainians making those weighty decisions...
Personally, I just call them Soviets, but since you continue to spin things based on ethnicities I thought I'd point the Ukrainians running the show out to you.
So how far do you have to go from the kremlin in the center of mockba to find any Russians?
