 Modern gun-artillery such as the L118 105mm light gun is used to provide fire support for infantry and armour at ranges where mortars are impractical.Man-packed mortars lack the range or hitting power of gun-artillery.In between is the rifled towed mortar; this weapon (usually in 120mm calibre) is light enough to be towed by a Land Rover, has a range of over 7,000m and fires a bomb comparable in power to a 152mm/155mm artillery shell.
