The Invaders are a Space Marine background chapter that has picked up notic as Matt Ward likes to add them in his codexes. They have the luck of Lamenters while the grit of Crimson Fists often heading right into the next battle despite having little to no time replacing their losses.

Their biggest accomplishment was destroying Craftworld Idharae how the hell they did that we don't know (it would seem they simply damaged it beyond repair) just that they took and insanely high casualties that they still didn't recover form in 43 years when Alaitoc showed up with Idharea's survivors at their home world. Only three hundread made it out and they were forced to become fleet base.

17 years later they lost two full Terminator Squads trying to teleport them down to the Necron World Engine.

One year later, the try to liberate and planet that Ahriman took over only to set off a trap Ahriman made which resulted the planet being ripped and teared by warp fire by the time the Grey Knights show up the fix the mess only 12 of the 300 marines they sent were alive.

Currently they're fighting Hive Fleet Leviathan thanks to Craftworld Iyanden.
