The Hover Multiple Launch Rocket System, also known as the Hover MRLS, is a fast attack vehicle used by the Global Defense Initiative in Tiberian Sun.
These mobile rocket launcher systems were developed after the First Tiberium War and were designed to replace the aging M270 Multiple Launch Rocket System which had served with distinction during the earlier conflicts against the Brotherhood of Nod. The Hover MLRS had heavier armor than the previous version, although not as much as either the Titan or the Tick Tank. Its main advantage, instead, was from GDI's use of hovertech to propel the MLRS. No longer would the vehicle be forced to remain on land. This unit could also maneuver in calm bodies of water, crossing rivers or even entire oceans if necessary. Furthermore, this means that the Hover MLRS unit was also quite fast, making it an able scout. However, there were also disadvantages with this approach.
For one, the advanced Hover drive failed when exposed to the massive charged particle bursts of an ion storm, rendering the unit little more than a missile turret. Second, the Hover MLRS' missiles were not extremely powerful against most units. Unlike the previous incarnation, the Hover MLRS had little capacity against infantry and only a moderate capacity against vehicles and aircraft. It should be noted, however, that the Hover MLRS units were GDI's only mobile air defense (with the exception of the Mammoth Mk. II, but it wasn't very effective against aircraft to begin with) against most Nod aircraft attacks.
