KO aether strike force

[Dave]

Just a quick question about the sky wardens in this battalion. In the KO book it says they have to be in there but the app says they’re optional . I know the book is the one to be trusted but just wanted to check this hasn’t been changed with an faq or anything .

Cant see the app version as it requires you to have purchased the book in the app, but you are correct the physical book (plus and FAQ) takes precedence over any other forms.

If you can, email GW about the issue, its obviously incorrect but not many people would spot it (having book in physical and online form).

I would say it is an error of the app. The point is, optional units are often written like that: 0-2 not with a fix number, and neighter in the battletome nor in the Errata they are not optional.
