New guy looking for help: Making intros and getting airlifts.

[Agent JB]

Ok, so I'm a n00b with the whole scripting thing... I was wondering how I do Intros (or cutscenes, depending on who tells the story) and airlifts. 
For example:
The intro of the mission (singleplayer) I want to show a couple of Marines (BlueFOR) in a firefight with the enemy, and they get shot up *but not killed*.
The mission will revolve around getting to these marines, with re-enforcements and an airlift to base. 

Any ideas on how to do it? 

*sorry if its in the wrong section*

By the way... I'm a very inexpirienced scripter... so if you could explain it in completely n00b terms please.
Currently, I'm using the Editor ingame to do everything... but I only understand the waypointing, unit placement, and triggers (basic) to end the game.
