context_page_description: In military usage, a barrage is massed sustained artillery fire aimed at a series of points along a line. As well as attacking any enemy in that line, a barrage intends to suppress enemy movement and actions through that line. The points along the line may be 20–30 yards apart, with the total line length anything from a few hundred to several thousand yards long. Barrages can consist of multiple such lines, usually about 100 yards apart, with the barrage shifting from one line to the next over time, or several lines may be targeted simultaneously. A barrage may involve a few or many artillery batteries, or even a single gun. Typically each gun in a barrage, using indirect fire, will fire continuously at a steady rate at its assigned point for an assigned time before moving to the next point, following the barrage's detailed timetable. Barrages typically use high-explosive shells, but may be shrapnel, smoke, illumination, poison gas, or potentially other chemical agents.
context_section_description: The barrage continued in use into the Korean War. At the Battle of Pork Chop Hill, UN forces employed on-call, pre-registered defensive fires called flash fire to defend its outposts, in which artillery laid down a box barrage in a horseshoe-shaped pattern around the outpost. It was still in use in the Vietnam War.
  In the 1982 Falklands War, the assault of 42 Commando Royal Marines on Mount Harriet  was preceded by a moving concentration from supporting artillery, firing some 100 metres ahead of the advancing Marines. Later phases of the attack used a pepperpot fire, including Milan anti-tank missiles.  However, neither of these were true barrages with fire aimed at successive lines to a strict timetable.  The term Barrage as a method of fire control was not included in the 1965 ABCA artillery agreement nor its successor NATO STANAG.
