LOL. Because almost all our artillery isn’t self propelled. Shoot and scoot is standard.
US counter battery fire is not just generations ahead of anyone else, but it is insanely deadly. It uses any number of *correlated* intelligence gathering from satellite on down to ground, and within seconds can target every *possible* target on the entire battlefield.
Their biggest potential problem is running out of shells.
What? Don’t the Russians have self-propelled arty? Using yanks in an SP role is wasting the tank asset and using it as an inferior artilley system. Wasteful and stupid — unless you have no SP artillery worth the name.
