The Yellow Jackets are a Loyalist Second Founding Chapter of Space Marines of unknown origin. Emerging as a distinctive Chapter during the subsequent Great Scouring, this Chapter quickly became known for their lightning raids and hit-and-run attacks launched from Thunderhawk Gunships. For ten millennia, the Yellow Jackets have continued to steadfastly serve the Emperor of Mankind, both faithfully, and valiantly.

Chapter HistoryEdit

Yellow Jackets Chapter Colour Scheme

Following the end of the Horus Heresy, Roboute Guilliman, Primarch of the Ultramarines Legion and author of the newly-scribed Codex Astartes, was responsible for the restructuring of the Imperium's military forces. The vast Space Marine Legions would be broken down into numerous, smaller existing formations, known as a Chapter. When the Second Founding of the Space Marines was decreed seven years after the death of Horus and the end of his Heresy, most of the old Loyalist Legions divided into fewer than 5 Successor Chapters, but Guilliman's own Legion was divided many times.

The newly Founded Space Marine Chapter, known as the Yellow Jackets, emerged as a distinct Chapter after the terror-filled era of the Heresy. During the Great Scouring, when the Imperium was venting their wrath by driving the remnants of the Traitor Legions of the wretched Warmaster towards the Eye of Terror, the Yellow Jackets were cut off from the bulk of Imperial forces. The Chapter began a campaign of hit-and-run attacks launched from Thunderhawk Gunships. The sudden appearance of these warriors pinned down and paralyzed vast enemy forces and fear of their retribution prevented many a Planetary Governor from going over to the service of Chaos. In the ages since, the Yellow Jackets have continued to serve the Emperor of Mankind with distinction, including their heroic stand against Warlord Graznik and his mighty Ork WAAAGH!

Chapter AppearanceEdit

The yellow coloured squad specialty markings -- Tactical, Devastator, Assault and Veteran are located on the right shoulder plate. Sergeants are designated by the skull symbol worn on their helms whilst officers are designated by their red-coloured helms. The right knee is painted in the company colour in accordance to the Codex Astartes -- White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company) ect.. A black coloured Roman numeral is stenciled on the right knee plate, indicating squad number.
