BAS Choppers, rappeling and cargo questions

[Black Ops 8]

I need to know how to do 3 things.

MH-47 Cargo, how can I make a West jeep/MG start INSIDE the cargo at the start of a mission while the chopper is flying?
Same thing again, but with a Humvee fastened to the bottom of the Chinook?

Last but not least, how do I make a MH-60L with a group of troops rappel troops out of the chopper by script, not by manual group leader command(as if you were the leader and told them to rappel)?

I posted this before in another forum section and didnt get much help.
