How to unlock the The Russian reversal achievement in Iron Sky: Invasion - Definitive Guide
For those who do not want to use a walkthrough, all side missions are gotten from the Korean Space Station once you jump (fast travel) to it. Side missions one through four are triggered in Chapter I but might be available at a later point if you haven't completed them already although I cannot vouch for it. The final side mission, 5, is found in Chapter IV.
There are 5 Russian side missions in total. You trigger them as objectives by fast-travelling to the Korean space station, as soon as you arrive you’ll see a cutscene with your next objective.
These particular side missions are important because the final mission sees you fly the Banzai, which is necessary for platinum, because you’ll receive the The emperor protects trophy.
Always fly between the 3 space stations after you’ve completed a few main objectives because these side missions unlock gradually. You won’t be able to do them all right away - the final set will be available after you have destroyed the 3 zeppelins in Chapter 4. They vary between reconnaissance, capturing and/or destroying enemy ships, and gathering salvage to sell there. They are all very self-explanatory and once you have completed the final mission, the trophy will unlock.
