When the US and coalition forces invaded Iraq during both Gulf wars, what preceded the ground forces going in was a months of heavy air campaigns bombing Iraqi/enemy targets day and night. then the Iraqi army didn’t just underestimate the allied capabilities, they expected them to drive on highways and line up in front of their objectives, the same way the Iranian army did. They were caught badly out as the allies drove at them from the deep desert, through a sandstorm Abraham’s had GPS at the time, allowing them to drive straight through the desert with no risk of getting lost.
