Datasheet data comes from a community-maintained repository (not official Games Workshop / Wahapedia data), so it may lag behind the latest balance update or errata. Detachment rules are shown for reference only and are not applied to the math — use the advanced modifiers above to reflect anything relevant. Chapter/sub-faction books that don't define their own detachments (e.g. Black Templars, Blood Angels) show the core book's detachment list instead, since that's what they actually use. A few niche armies have no detachment data at all yet. The calculation also doesn't include auras from other attached units, stratagems, or mission/objective rules. Damage allocation assumes the attacker spreads wounds to kill as many models as possible.
