'''Heavy Quad-Launchers''', also known as '''Thudd Guns''', are four-barreled light field artillery pieces originally produced by the [[Squat]]s.¹ Invented by their Engineers Guilds on the Squat Homeworlds, they would later share the design with the [[Adeptus Mechanicus]], who copied and produced their own version for use by the [[Imperial Guard]]. The weapon received its nickname from the distinctive and rhythmic "thud" sound produced as each barrel fires in rapid succession.¹ More commonly used by the Imperial Guard in the past, the heavy quad-launcher has been largely relegated to [[Regiment#Siege_Regiment|siege regiment]]s and garrison forces.^2,3 The weapon was employed during the [[Horus Heresy]] in [[Battle of Terra|defense of the Imperial Palace]] and has seen recent use in the [[Badab War]] as well as the [[Tyrannic Wars]].^4-p92

The original thudd guns were mounted on a special motorized tractor, which could be controlled by the gun crew with a radio control box.¹ However, later models used by the Imperial Guard, such as the Lucius Pattern, must be towed into place, either by a [[Trojan]] or [[Centaur]] vehicle.^2,3
