One thing I would change...............

I hope this debunks the myth that running through minefields in trucks is a good thing to do with your engineers.

That depends on whether they are covered, and on how many engineers you have. If there are 3 minefields that your men wouldn't be able to move into by foot, whilst you also have 3 engineers, it can be worth it if the minefields are either not protected or you can blind the protection with smoke.

Obviously, simply driving your men around the map in trucks straight into the enemy defenses will get them killed like you say, but there are situations where it can be useful to do so.
