A barrage is a term used to describe extensive artillery fire against enemy positions. Barrages were classified as light, moderate or heavy. A light barrage amounted to six or seven shells every ten minutes. A moderate barrage was thirty shells a minute and a heavy one, fifty to sixty shells a minute.
When performing the Overwhelming Barrage action, the character fires all weapons of a single type (heavy turbolasers, medium ion cannons, etc) within a single firing arc. This action requires at least two weapons to use, and cannot be used if there are not two weapons of a single type in the chosen firing arc.
