- Relief of Jakal II (409.M40) - A strike force from the Warmongers Chapter, based around the 2nd Company and reinforced by squads of the 1st, 8th and 10th Companies, deployed by Thunderhawk to the defiled Shrine World of Jakal II. The month-long operation effectively destroyed the Dark Eldar Kabal of Crimson Tears, though what the aliens intended was never ascertained.
- Allegiance of Terra (Battle Barge)
The Warmongers primarily wear midnight blue Power Armour, which includes the torso, arms, groin and legs. The Aquila or Imperialis on the chest guard, as well as the power pack, helmet, shoulder plates and greaves, are bone white. The open-faced, midnight blue squad specialty symbol -- Tactical, Devastator, Assault or Veteran -- is located on the right shoulder plate. A midnight blue Roman numeral is stenciled in the centre of the squad specialty symbol, indicating squad number. The colour of the shoulder plate trim indicates company number in accordance with the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company), etc.
The Warmongers' original Chapter badge was a large white skull pierced by a yellow sword through the top, point downwards, on a field of green. Their current Chapter badge is a large white skull pierced by an ebon sword through the top, and all the way through, on a field of bone white.
