The Land Speeder Vengeance is a variant of the standard Land Speeder and is used only by the Dark Angels and their Unforgiven Successor Chapters and is the deadliest weapon available in the Ravenwing's arsenal, a larger variant of the standard Land Speeder that is armed with the devastating Plasma Storm Battery, with which it lays down a blistering barrage to support the Dark Angels' attack. The Land Speeder Vengeance couples a larger chassis and four powerful gravitic lifter-engines with a ferocious heavy weapon load-out, providing the elite 2nd Company, Ravenwing with a highly mobile and deadly support battery to aid them in their hunt for the Fallen.
The Ravenwing have always sought more firepower to support their hard-hitting attacks. An answer to this quest came in M36, with the discovery of the STC for a strange type of Land Speeder. Its larger chassis and supetior lift-engines could house heavy weaponry, allowing it to mount the plasma storm battery - a relic weapon long held in the armoury of the Dark Angels' mobile fortress-monastery known as The Rock. Thus was born the Land Speeder Vengeance, a strike vehicle exclusively employed by the Unforgiven Chapters. In conjunction with the Land Speeders of the Support Squadron, the Land Speeder Vengeance has proven its worth on the battlefield time and again, able to keep pace with the fastest of the Ravenwing vehicles and able to deliver devastating volleys from its deadly plasma storm battery.
