How to create Killmongers Chaos Warband in Space Marine 2

How to create Killmongers Chaos Warbands. Their only citation was in Codex: Chaos Space Marines (4th Edition). They are more than likely devoted to Chaos Undivided. This is little other information on this obscure warband in known Imperial records. We only have this image from WD pages: https://ibb.co/3995cdbH We have a color scheme but not any warband's logo or icons...what a pity!
