Well, to some extent.
For the "fighting on a hill" thing, they didn't implement hull-down, which would be kind of an important factor in the real world. And a lot of the drawbacks to heavy tanks, like logistics issues, didn't really apply. So in practice, just place heavy tanks on hills (since you don't have to do much to maneuver them there, set them to attack, and ignore them for most of the game until the fighting dies down. It's...not super engaging.
For the ambushes, you get to pre-position your forces, knowing pretty exactly where the enemy forces are, and both sides basically transport a substantial mass into place at one time. Kinda like teleporting two sides together into close proximity, and the computer not sending out reconnaissance units to feel out the other side, just starting a rush over open ground.
I still don't think that Starfield is a bad game. I can understand some of the complaints, but it really amounts to a "does not equal some prior Bethesda games relative to their release times" for me.
One of the big ones, wanting to wander around a big outdoor overmap and just stumble into things, mostly also applied to the kinda-Fallout-like The Outer Worlds, and it didn't take nearly the Steam review beating that Starfield did
I'd call The Outer Worlds a substantially worse game, myself.
