Question about objective secured and multiple detachments

I just wondered if someone could clear up something for me, I think I've got it right but always helps to check with you lovely peoples!

If I have a real space raiders detachment and for examples bring

1 x archon
2 x 5 kabalites
6 x unit of 5 scourges


AND then have a CAD with for example

1 x succubus
4 x 5 kabalites in venoms

Do the CAD warriors and venoms have objective secured?

Sorry for the probably silly question I just struggle with the many permutations of CAD, unbound, allied, formations and dataslates!

Yes.

EDIT: Detachments have a lot of people confused I think. I look at it this way.

If it has a force organisation chart, it's a detachment.
Formations are also detachments (brb states this), but they require you to take certain units, not just a certain number of units from a particular slot.

Detachments have special rules (called command benefits). These only apply to the units from that detachment.

If you have models that don't fit in a slot from the detachment then they are unbound.

Thanks Boss, thought I had it right but hate the idea of turning up with a wrong list!

Thanks again.
