nd modern armor could destroy both of them with pinpoint accuracy while moving full speed over rough terrain outside of radar range (e.g. what happened in the invasion of Iraq).

lol, that is NOT what happened in Iraq. The tanks were sitting on low boy trucks for the vast majority of the invasion. How do I know this? Because they were in my convoys.

Even for major offensives after the initial invasion, that's not at all what happened. They were basically employed as large mortars, sitting about a half mile outside of a town, and leveling it.
