The main thing that will make any sim unrealistic and accusations flying like comets;
In RL you would never ever get this amount of practice of any one item, better yet many.
The "Annie Oakley" effect of using a .22 cal rifle in target tricks like splitting a playing card takes us out of the realm of any "norm". No matter the opinion, the brain grabs on to it, sometimes distracted by it.
The human brain is incredibly good at detecting skill in games, especially when someone performs something so precise, fast, or unexpected that it almost feels impossible.
Your brain is constantly predicting what will happen next. What's interesting is that your brain doesn't just recognize the action itself. It recognizes the difference between what it expects a human to be capable of and what it just witnessed. This happens through a process called predictive processing. When someone performs an incredible skill, your brain notices that the result doesn't match its prediction.
Your brain is constantly learning what is normal. When it encounters something that breaks those expectations, it detects an anomaly.
This is closely related to prediction error: your brain expected one outcome, but something very different happened. An anomaly doesn't necessarily mean something is impossible. It means something is sufficiently unusual that your existing understanding struggles to explain it.
In the 90s I worked with David Copperfield. I helped test the trick props. I did a 7 show run with him, so it was almost daily. What my brain had to grasp was, the theatrical lead-up is actually seeding the viewer's brain and setting it up on what it should expect. Your eyes will not be where they should be. Those tricks were so easily done it shocked me that anyone was fooled. But when I watched the show, after spending hours setting up special lav microphone systems, testing lights for shadows in the right places, sight-lines...etc. then seeing it operate it was convincing, even though I knew how it was done.
Point being. The practice level of skill is a mental distraction within itself....in any game. It would not happen like that in RL without 10,000 hours of practice. So the repetitive gaming environment creates anomalies.
I can see a nose-on approach of an AC to a tank is a smaller but steady predictable target. I thought about well the way it's setup it pulls us into that extra edge, but then,... would we need a 3-4 player crew to run the tank if that was separated? I think any game would allow you to bounce around.
But wait there's more,... The human body can suffer serious internal injuries if bounced around like some fly.
All that said; B-17 "Death Stars", loaded with 6-8 players were epic fun.
