Joint Operations Task Force Metallus contains all major forces of the IoM. Imperial guard, Astarties(Crimson Fists, Imperial Fist, Black Templar), all major Ordos of The Imperial Inquisition & associated chambers militant, Skitarii & AdMech militant forces, Imperial Navy & a minor Knight House. I'll admit I have a lot of AdMech stuff I need to get up to table top quality.
