Tanks (medium tanks as soon as possible, bonuses come from research treaty with Germany).Air Doctrine (operational integrity as it minimises your plane loss).Land Doctrine (superior firepower – see next section for more details).Industry (concentrated industry and construction before anything else).Electronic Mechanical Engineering (do this part of the tree as you go on, as you get research deduction bonuses).So, here is a list of priorities for your research: The navy and air force have been getting off easier so far (navy and air advisors not very important in comparison to division recovery).īy having an advanced military, this will give you an upper hand over the enemy.Tukhachevsky refuses to confess, but cannot be allowed to live (if you decide to go down the Collectivist Propaganda root, I’d recommend choosing the first option).He must go (this choice is the easiest as Khrushchev is pretty irrelevant). Khrushchev dabbled with Trotskyism in the past.Here is the three choices I recommend choosing during the Great Purge: Once the purge is completed, you will suffer some penalties such as longer research time, due to purged officers, but once that runs out you can capitalise on the military might of the Union of Soviet Socialist Republics. Unfortunately whilst playing as the Soviet Union in Hearts of Iron IV, you have to deal with Stalin’s Great Purge. I will explain what you should do during the ‘Great Purge’ below. In addition, it is very important to note that you cannot leave the ‘Great Purge’ to late, or else it will ignite a civil war, which allows you to bring Leon Trotsky back, which I will try and explain in a future guide. Overall, if you follow this procedure for your national focuses and political power spending, you cannot go wrong you build up a formidable industry and have a modern army by the time the Axis invade you. Konstantin Rokossovsky (do the rest of the military staff after the Great Purge).War Economy (as soon as you can as world tension needs to be at a certain level).I will not list every single one, but the ones I feel you should go for first. The following recommendations are based on my military tactics, which you can find a little bit further in the guide. Moreover, here is a list of how you should spend your political power, on advisors and laws etc. In terms of the order you should do your national focus tree, here is what I have found works best for me. Although, you miss out on 15% national unity, the ability to research technology quicker will give you a significant advantage over your foes. You must focus on the construction of civilian factories before military factories to ensure your construction speeds of other buildings are speedy.Īs previously stated, I highly recommend that you go down the ‘ Positive Heroism‘ side of the national focus tree, as you get access to Konstantin Rokossovsky, and lesser research times.You must rival the German Luftwaffe (air force) to ensure you have air superiority, which is important no matter what land doctrine you go down.In your national focus tree, you should go down the ‘Positive Heroism’ root as opposed to the ‘Collectivist Propaganda’ as you get Konstantin Rokossovsky (Armor Genius) and higher research reduction times, making you more advanced by the time you go to war in 1941.The Soviet-German Research Pact, Great Purge, and Molotov-Ribberntrop Pact must be followed, as you obtain a higher national unity, research bonuses on medium tanks, and take Eastern Poland after the Germans invade Poland in 1939.Also, let me know what nation you would like to see in my next guide in the pool below. I’ve also released France Guide, Communist China Guide, The Netherlands Guide, and German Reich Guide. Therefore, lets proceed into the guide.Ĭheck out my other nation guides. With this, you may be wondering what the guide is actually about? Well, the tips will provide you with the basic knowledge as to how the Soviet Union works, and some strategies that I have found effective, which you can attempt to apply during your games.

However, I use a somewhat different tactic to a lot of players, so the advice I provide may not be your cup of tea, but I have found it gets effective results, particularly against the Axis forces. With the potential for massive industrial expansion, and perpetual manpower, the following tips should help you to make the Soviet Union an unstoppable force. Novelties aside, the Soviet Union is one of the most entertaining nations to play as in Hearts of Iron IV.
