Can you deploy a unit embarked on a transport? Or, do you have to embark turn 1 and then disembark turn 2 (or later)?

You can find this under Transport X on the RRG (page 57):

"During setup, if a player has deployed a vehicle with the transport x keyword, they may choose, as one of their alternating deployments, to deploy an eligible unit such that it is being transported by that vehicle."

Thank you!
