THANK YOU!
I was avoiding posting to this thread because I'm getting tired of all the formation/detachment threads. It seems like this gets explained every week.
A Formation is a special type of Detachment, that on the upper corner of the Datasheet has the symbol of 3 skulls joined by a circle. They are generally highly specific in terms of what you must take in them, though there is sometimes a tiny bit of flexibility.
A Craftworld Warhost is a special type of Detachment, that contains a 1-3 Core choices, 1-12 Auxiliary choices per Core, and 0-3 Command choices per Core.
SOME of the Auxiliary Choices are Formations, while others are not. For example, a Wraith Host is both an Auxiliary choice AND a formation (see the little skulls on the corner of the datasheet...), while Wraith-Constructs does NOT have a datasheet and is NOT a Formation. Likewise, you can't just take 1 unit of Rangers because "Ouctacsts" is NOT a formation (though it is an auxiliary choice).
Not that complicated, right?
