This is how I want the Soviet Union National Advantages to be:
1. Russian Winter
Russia’s greatest ally was its winter cold. Germany’s invasion stopped dead as the snows came down.
Once during the game in your collect income phase, you can declare a severe winter. Until the start of your next turn, your infantry defend on a 3.
2. Nonaggression Treaty
The Japanese refrained from attacking the Soviet Union during most of the war. They already had one bear coming at them from the east.
The first time in the game that the Japanese forces attack any red territory, you may place four of your infantry for free in that territory before resolving combat. If Japan attacks more than one red territory in that turn, you may decide which such territory receives the infantry. If you attack an orange territory before Japan attacks you, you lose this national advantage.
3. Guard Tank Regiments (replace Mobile Industry)
Russia used heavy tank regiments as guards of Moscow. Invulnerable to any standard anti-tank weapons available of that time, these tanks were instrumental in saving the capital.
Your tanks in Russia defends on a 5.
4. Conscripts (replace Salvage)
The Red Army won many battles with their raw manpower, by using untrained infantry and many times unequipped.
During your mobilize new units phase, you may place one of your infantry for free in any red territory if you control it. This free unit is in addition to the group of units you just purchased.
5. Katyusha Rockets (replace Lend-Lease)
The Soviets were able to supplement the artillery with massed batteries of rocket launchers. The sheer volume of fire more than compensated for individual lack of accuracy.
Your artillery attacks on a 3, for the first combat cycle only. Thereafter, only one artillery unit can retain this increased attack factor of 3.
6. Trans-Siberian Railway
The Trans-Siberian Railway spanned 10,000 kilometers from Moscow to Vladivostok, the longest main line in the world.
In the noncombat move phase, your infantry, antiaircraft guns, and artillery may move 2 territories per turn only among these territories: Russia, Novosibirsk, Yakut S.S.R., and Buryatia S.S.R.
