If you have good knowledge, links, books, videos... about international military and/hybrid war balance, you can put it here or ask about these topics. And no matter is your writing about fantasy world politics, history, communist idea of marching through institutions, love & romance, bank robbing cowboys, drug cartels... Conflict is the base element of writing. The more multidimensional, complex and interesting you can make your conflicts, the more you can hook your reader. The dynamics and structures in the wars and conflicts stay same. Substance, tools, means... vary. There is a lot to learn in this topic.
Mattis about hybrid warfare & needs concerning military thinking. (I really like the structure and dynamics of his thinking - no matter what is the substance.)
