“This is why long-range precision fires is number one for the Army. So, if I need to, for example, suppress enemy air defenses using long-range artillery, I have the means to do that, reaching deep into the enemy’s rear. What that does, if I can suppress enemy air defenses, either the guns, missiles, radars…ect.. it helps clear the way for the Air Force to do what they do – and do well,” [Army Secretary Mike] Esper said.
That's what I got out of the Army call for long-range fires when I wrote about it last month. This makes the linkage absolutely clear.
