Previously posted this to the opr sub-reddit. I made some homebrew rules using the points calculator and parts of the Human Defense Force army list for fielding traitor militia. The stats reflect the old Forgeworld Chaos Renegade models as a basis, so are most easily represented by those or similar models.
Updated rules for Grimdark Future to fix a few spelling and point cost errors, also changed the Soldiers of Fortune special rule to make Mercenaries more viable for their higher points costs. Added rules for using Rogue Militia Grimdark Future Firefight.
