Ye-es, except in larger scale. The maps we have tend to represent an active battle. The 'realism' in this case won't usually include moving guns around at trot speed and simply repositioning them so easily.
They are real time battles, 45minutes = 45 mins real time usually, so having trucks suddenly reposition guns etc, doesn't quite work. It's borderline RTS, and begs the question, why not move on to building bases etc.
The compromise we have is the small additions of portee, push-able guns and deployable weapons.
That plugs the gaps, nevermind the mg kits, mines etc.
I would like things like barbed wire gates that can be extended and destroyed/ cut to make some interesting choke points, but again, it walks a fine line between raw Shootempup and RTS.
Evolution is subtle, not drastic.
