The Fabulous Disappearing HQ

I've more or less finished building 1st Ranger Battalion - pictures later.  

Next was going to be the Ranger Force HQ.  I say "was" because it now appears there wasn't such a thing.  By the time of the Anzio landings a 6615th Ranger Force had been constituted but it now appears this was a response to the problems co-ordinating Ranger operations at Salerno. 

Colonel William Darby was the father of the modern Rangers and was seen as their commander at the time but strictly speaking in September 1943 he was only commander of the 1st Battalion.  He directed the Chiunzi pass battles without the benefit of a properly constituted brigade/regiment HQ.

What does this mean for the game?  Not a lot, I suspect, but it does rather suggest that I need to add a specific Darby figure to 1st Bn's four figure HQ.
