Open pedantry:AP, and others, constantly use the word “barrage” to describe any attack by artillery or rockets on a target. It’s a bit annoying. Barrage actually has a technical meaning in military language. It refers to an artillery bombardment that moves ahead of the advancing ground troops. Thus a barrage would describe artillery firing ahead of advancing infantry, and the artillery would retarget further ahead of the infantry as the PBI advanced near the previous targets. The fire might be lifted on a schedule, say every ten minutes the fire lifted and retargeted two hundred yards ahead of the previous spot. The barrage was developed in WWI to support infantry attacking trench lines protected by cordons of barbed wire. I wish they would just use “bombardment” instead.:Close pedantry.
