Saturation fire
Saturation fire is a level of intensity of artillery or machine gun fire that is very high and is designed to fill an enemy position with artillery shells or machine gun fire [Encyclo.co.uk].
Saturation fire might be used to bombard an area just before an offensive. Another kind of intensity that is also used to bombard an area during an offensive is a creeping barrage. Saturation fire is used most of the time before an offensive to bombard an enemy area and lower enemy morale and ability to fight.
In the Battle of the Bulge, German troops used Werfel rocket batteries to do saturation fire on Allied positions, particularly prior to an attack. Benjamin Colby claims that the U.S. did saturation fire-bombing of Dresden in 1945.
During the Vietnam War, the US used saturation fire against the Vietnamese forces. In one example in 1972, US air forces did saturation fire around a bunker where seven US advisers alongside a number of South Vietnamese ARVN soldiers were surrounded by NVA forces which had been subjecting the bunker to a withering attack for days. The use of automatic weapons for saturation fire has been criticized by a major US gun maker. He argues that using carefully aimed semiautomatic fire can be more effective than sweeping enemy positions with random, full-automatic fire [Military Wiki].
