For the past few decades, the US has been overly confident and believes it is invincible, leading to a mentality where they only attack others and not the other way around. Because of this mindset, they suffered significant losses of their HIMARS in Kuwait.
The position should have been moved quickly to another location after firing, but their belief that they would not be attacked due to the adversaries' missile accuracy(satellite discrupted) resulted in these substantial losses.
