Good afternoon, I do not understand what the problem with the search, especially since you say that you have looked in the search engine is quite a lot of interesting options, so the first could look better in the search engine, and then, in case of failure and the forum would ask for advice. Of course, if you still can not find anything, then I can recommend you to read about the activities of Alexandr Katsuba on the website of the project "SB News Room"
https://www.sbnewsroom.com/to-each-their-own-wartime-superpower/ . The article is sufficiently detailed in all aspects of the activities, so I'm sure a hundred percent, you'll be able to find useful information to familiarize yourself with. I hope that I was able to help in this matter. Good luck with studying the material, friend!
