Diamond Knights

The Diamond Knights are an Ultima Founding Successor Chapter of the Ultramarines comprised entirely of newly revealed Primaris Space Marines. This chapter, unlike their predecessors and fellow successors, only refer to the Codex Astartes in times of battle, if at all. Despite being a young chapter they have fought many battles on behalf of the Imperium and are on constant crusade to defend Mankind from all who would do them harm.

History
The Diamond Knights were founded in the aftermath of the Indomitus Crusade. Their Chapter Master, Marcus Lucullus was a Captain in the Unnumbered Sons and displayed great leadership and skills in battle. As such he ws commanded by Lord Guilliman to establish the Chapter. When the Chapter was built Marcus chose to lead under the title of Lord Commander to honor his Primarch; he also proclaimed a crusade against all enemies of Mankind.

Chapter Homeworld
As a fleet-based Chapter, the Diamond Knights now have no official homeworld. Instead, their fortress-monastery is situated onboard the fully mobile star fort Diamond Keep. The rest of the Chapter serves aboard the fleet of Strike Cruisers and other Battle Barges that were assigned to the Diamond Knights when the Chapter was founded.

Combat Doctrine
Deep Striking is a large part of the Chapter's combat doctrine and it mainly conists of deploying melee squads with ranged support from either Hellblasters or Aggressors. This is seen extensively in the second and third companies, both companies have at most two intercessor squaads that are equiped for melee combat alongside their Inceptor and Reiver squads. In order to make melee combat more effective and too get the melee Intercessor and Reiver squads over dificult terrain, they are more often or not equipped with modified grav-chutes. Siege Wafare is another key part of the Diamond Knight combat doctrine, their favoured defensive tactic is the infamous "Steel Rain" tactic, which involves keeping a percentage of the company in orbit as reserves.

Chapter Gene-Seed
Being both Primaris Marines and descendants of the Ultramarines, the Diamond Knights gene-seed is very stable and show light signs of flaws or mutations.
