Try out the apache helicopter in the free, moddable game Operation Harsh Doorstop with a gunner, preferably someone on mic so you can hear them laugh maniacally as they play the most absurdly destructive, armored brigade annihilating, combination of a rollercoaster, shooting gallery and indecent powertrip imaginable.

As a pilot you can see where the gunner's crosshair is aiming, so they function as your nose to sniff out dense targets for your rockets. The box indicates the valid traverse angles the gunner turret can fire in.

The attack helis are basically a dragon from skyrim in this game, except they can see you from a mile away and hit you before you even realized they were at a firing angle OR come from just above the tree tops at 100mph and roast you with rockets ...and they can switch between the two strategies so effortlessly it makes them extremely hard to anticipate when crewed by an experienced CAS pilot.

In short, in some ways they are fairly realistic.

It is kind of terrifying (until you get a stinger or AFV cannon trained on a pilot that has gotten too cheeky).
