Quite the contrary, I love this subgenre more than any other one regarding shooters. But I've never seen it done right. If you know any game that doesn't end in frustration about the AI, please tell me.

I'm more than OK with micromanagement in games, but that's not how it should work in shooters. Men of War is a good example, it's a strategy series with a notorious amount of micromanagement, but the difference is, you get all the information needed to manage your units and you as a player are not part of the battlefield. No enemy unit can look up in the sky and shoot down your birds-eye camera. But in shooters, not only do you have limited information about your enemies and your own team, you can also be killed during micromanagement. This is not how it should work. Your friendlies being a little bit more pro active is the least one could ask for.

Like imagine you storm Osama's hideout and every time your soldiers have to ask you - the captain if its OK to shoot the terrorist in the room, or if its OK to move onto the next room, or its OK to take cover, that's how it feels.

And because you're essentially responsible for every single action of your team, you also feel responsible for every single mishap, whether it actually was your fault or not.

Also modern shooters themselves have already fairly demanding controls, pairing that with the ability to command different units means compromises have to be made in user experience. Your commands are usually limited by line of sight, you can't tell your units to advance behind this wall and search for cover. Arma 3 tries to address this issue with the "Command Mode" that let's you zoom out the camera to a birds-eye view, but that's essentially what a strategy game is anyway. You also can't command multiple squad simultaneously, each squad needs separate attention, while the AI computer can do everything at once, putting you even more at a disadvantage.

Developers also rarely bother implementing actual military techniques. The only 2 examples I can think of are Arma 3s combat advance (half the units cover, the other half moves) or Ready or Not's room clearing. What ends up happening is, people just take 4 machine gunners with scopes or 4 snipers, since all units essentially behave the same AI wise, there no downside to that.

In my opinion a squad control game should essentially play itself, meaning that if your character dies, the rest of your AI should be smart enough to finish the mission or at least retreat on their own, just like a real squad would if their commander dies. The challenge shouldn't come from janky controls or cheating AI, it should come from having the odds stacked against you. The goal shouldn't be to just finish the mission, but have everybody come out alive. A lot of those games become almost trivial, if you just leave the AI at spawn and run through the mission yourself.

I really recommended you the 2nd Misson in the Soviet Campaign in CTA Gates of Hell. It took me a good 3 days to get through it but its as close to All Ghillied Up as you can get.
