The impact points along the line may be 20–30 yards/meters apart, with the total line length of the barrage zone anything from a few hundred to several thousand yards/meters long. In addition to attacking any enemy in the kill zone, a barrage intends to suppress enemy movements and deny access across that line of barrage.
In military usage, a barrage is massed sustained artillery fire ( shelling) aimed at a series of points along a line.
