Thread: Can Battle Brother allies deploy squads in each other's transports?

Just wondering if Battle Brother allies can deploy in each other's dedicated transports?

Specific example:

If Dark Eldar take Kabalite Warriors + Raider and then ally with Eldar who take Dire Avengers + Wave Serpent -> Can the Dire Avengers deploy inside the Raider and the Kabalite Warriors deploy inside the Wave Serpent?

Or, even Warlocks in a Raider?

If not... can a Warlock unit embark in a Raider their first turn?


Thanks ahead of time for your answer!
