So my question is, when Building a Battle Forged Army you build an army comprised of detachments and specific detachments give you Command Points. So if I start the build with a Battalion Detachment I would get 3 CP so long as I had 3 HQ & 3 Troops choices minimum. Then I add a Vanguard Detachment, which is 1 HQ & 3 Elite. Now the question that springs to mind is, do the previously selected HQ count as an HQ choice for the Vanguard Detachment or does the Vanguard require its own HQ making 4 in total? Given the cost of HQ options in the Craftworld Codex it's going to be difficult to build a reasonable sized force and get CP's in anything 1500 or less, which is what they game around my way.
