A question about Transports

[XstaSea]

I see a lot of tactics discussion  about using transports to get strike squads into the action. I was just wondering, if you had a storm raven or a razorback that is filled with strikes, can you move the transport, then disembark the strikes in the same turn. Or do you have to disembark them at the start of the movement phase, so you move the razorback in the first turn and shoot with that, then in your next turn you disembark the strikes and shoot/charge with them?

 

If you do disembark, does that count as the squad having used up their movement or can you move/advance them as soon as they come out?

You must disembark at the start wholly within 3" of the vehicle, the unit can then move normally that turn, but will always class as moving in the case of firing heavy weapons
