Traverse (gunnery)

Gun laying is the process of aiming an artillery piece, such as a gun, howitzer or mortar on land, or at sea, against surface or air targets. It may be laying for direct fire, where the gun is aimed similarly to a rifle, or indirect fire, where firing data is calculated and applied to the sights. The term includes automated aiming using, for example, radar-derived target data and computer-controlled guns.
