I think it could be interesting, to have some options to adjust the perceived realism level, if you feel like it.

Ideas:

Allow the camera perspective only to be away from the closest squat leader / unit / your player up to a certain hight and distance. Or allow the camera angle only to point away from your unit, to not be able to peek behind walls and building. Or you have to set up "HQ points" and the camera can only point away from those points and reach a certain distance. And these HQ points can be destroyed by the enemy and this way you loose your eyes on the battlefield.

You could also make it super-realistic that you have to deploy drones in order to be able to bird's-eye-view the battlefield - and those drones can be downed by the enemy.
