Another huge mistake of many that the Army has made in recent years. From an infantryman and aviator perspective, nothing puts the fear of God into you and forces you to go to ground more than massed artillery fires.
The Russians and Chinese haven't abandoned that concept.
ATACMS was our big hammer when conducting the deep attack mission with apache battalions. One of those basically takes out a grid square.
Back in the day, we worked MLRS sensor to shooter missions at Ft. Stewart with Apaches in the late 90s. Digital fire mission from the bird all the way to the launcher. Took some effort, but we made it happen.
