LOL I live in the nation with the most powerful military in the world, in a city with the nation’s largest concentration of military personnel. I might know a thing or two.
But it really doesn't matter, because all of that is irrelevant. More on that below.
ChatGPT wrote that response, not me. Since you are concerned with my opinion, however, I'll share that below, but only because you asked so nicely.
This is, if you haven't noticed, a game, not "real-life [sic]". It's not meant to be realistic. How many generals you know do a good job while dead? (Ghost)
If you want realistic this is not the game for you. I don't want to play a game with logistics officers and taxes and government contractors and a "realistic civil administration." That sounds boring as hell. And you're alternately complaining there is no "supreme commander" and then in the next breath admitting "the user is sovereign." You're literally contradicting yourself here. My advice to you is quit this game and find one that suits you, or play longer than a month and give the actual game a chance.
