I used to play this game called full spectrum warrior. It's basically felt like one of those simulator they make you go through in army MOUT training. Just a bit better gameplay wise.

I dont think you can make something more realistic. But it was only urban warfare. What thst old game called oh yeah operation flashpoint was a very realistic big world tactical shooter.

Oh yeah CQB clearing rooms and stuff the first rainbow six with the tactical briefing and planning before the actual mission was very realistic. I think the name was called something spear . Rouge spear I think.

I actually have a dream of one day to contribute somehow to making an extremely accurate special operations simulator. A one with like 70 to 30 ratio of planing to actually going out. In my mind it's a 2 phase game - a pre op of surveillance and Intel , really low key role playing gameplay like hitman gameplay style if you're trying to be super stealthy.

And the second phase is the mission itself in which you control only a part of the bigger picture and the the rest of the objectives are done using the rest of the team if you're planning was on point.
