The Missile Storm Loadout was a weapon upgrade that featured on the Global Defense Initiative's AHV-8 Sandstorm MRLS. They were a notable newer development within GDI's arsenal and consisted of small "storm" missiles which were loaded into the Sandstorm's weapon pods and fired at a faster rate than standard rockets. This provided an increased fire rate to the vehicle drivers but came at the cost of accuracy.
As such, the Missile Storm Loadout was typically used against tighly packed groups of enemy units such as aircraft as the multiple overlapping shockwaves created by the "storm" missiles covered a small area which was effective against enemy swarms. This also meant that they were ineffective against single enemy units as the missiles accuracy meant that they rarely damaged the target. These upgrades were created for Commanders who sought to deal with the Brotherhood of Nod's Cobra aircraft.
