Allied Detachment cannot have the same Chapter Tactic as the Primary Detachment...

So, a Scout Squad or Tactical Squad to upgrade the Allied Detachment to a Combined Arms, or change one of the Detachment's Tactics.

Awesome, thank you!

I revamped the list yesterday so now I have the points to upgrade the Allied to a CAD. Sweet!

Can you give me a page reference for this? I'm curious.

He's right, I looked it up this morning. I want to say page 122? It says that an allied faction cannot be of the same faction as the other detachment/formation/whatever that it's allied with.

Just split the Tac squad in two five man squads and call it a combined arms detachment.

That is true, but the Codex Marines Chapter Tactics allow for ways around this.

Working off of eBook, so page numbers mean nothing, but it is listed under Chapter Tactics rules in the codex after their Warlord Traits. It's the same as 6th Edition in this regard, too:

"ALLIED DETACHMENTS
If your Primary Detachment has the Space Marines Faction, you can take an Allied Detachment (see Warhammer 40,000: The Rules) with the Space Marines Faction as long as it is drawn from a different Chapter than your Primary Detachment."
