In 857.M38 the Red Scorpions Chapter delivered the manufactory world of Helios from a massive Ork invasion of Waaagh! Grimgut. It is on this planet and in this conflict the Red Scorpions first developed the Land Raider Helios by putting the Whirlwind's rocket launcher on their Land Raiders. Orks of Grimgut using the low cunning sent force an infestation of Bomb Squigs and destroyed every vehicle attempted to press through city's streets. Then one of the Archmagos of Hive Manufactory 33 Delta Thule, from the ordnance foundry supplied missile launchers to Red Scorpions claimed that he received a vision from the Machine God himself. In this vision he have seen that if the rocket launcher would be fitting the Chapter's Land Raiders. they could able to mount the artillery support and would be immune themselves from the most concentrated efforts to overwhelm them, so soon the hive and all of Helios would be delivered. Red Scorpions agreed with him and started to make preparations. In the resulting battle the dozen converted Heluos pattern Land Raiders strike force deep into the Ork-held hive. As before, tides of Bomb Squigs erupted from the sewers to break against the vehicles. After the mighty explosions the Land Raiders stand charred black and spattered in Squig's blood but otherwise intact, while the Orkoid beasts obliterated itself to no effect whatsoever. Now the path to the infested ork's hive was open and the Grimgut was doomed. For returning the planet and its resources to the Adeptus Mechanicus, the Helios pattern missile launcher was prioritized for the Chapter's use. Helios would be assaulted by the barbarous Greenskins on numerous subsequent occasions, and each time the Red Scorpions would answer its call for aid. The Red Scorpions themselves disseminated the new pattern of Land Raider to small number of Chapters it has close relations with.

857.M38，红蝎战团将赫利俄斯制造世界从格里姆古特的Waaagh！的欧克大规模入侵中拯救出来。它就在这个行星上，在这场冲突中，红蝎首先通过将旋风的火箭发射器放在他们的兰德掠袭者上，开发了兰德掠袭者者赫利俄斯。格里姆古特的欧克使用低级狡猾的手段，派遣了大量炸弹史古格，摧毁了所有试图穿过城市街道的载具。然后，为红蝎提供军械铸造厂的导弹发射器的巢都制造厂的大贤者33德尔塔·图勒声称，他收到了万机神本人的神示。在这个神示中，他看到了火箭发射器是否适合该战团的兰德掠袭者。他们能够获得火炮支援，并且不会受到最集中的压制，所以很快巢都和所有赫利俄斯就会被不负所望。红蝎同意了他的意见，开始做准备。在随后的战斗中，十几辆改装的赫利俄斯型兰德掠袭者深入到了欧克控制的巢都中。和以前一样，炸弹史古格浪潮从下水道中爆发出来，冲击着载具。在巨大的爆炸之后，兰德掠袭者仍在那里，被烧焦了，溅上了史古格的血，但其他方面都完好无损，而欧克野兽则彻底消灭了自己，没有任何效果。现在，通往为患的欧克的巢都的道路已经打开，格里姆古特注定要灭亡。为了将行星及其资源归还给机械神教，赫利俄斯型导弹发射器被优先用于该战团。赫利俄斯随后多次遭到野蛮的绿皮的袭击，每次红蝎都会响应其援助召唤。红蝎将兰德掠袭者的新型号传播到与之有密切关系的少数战团。
