Check out the community guide there is a good tut on scripting that will get you started with basic scripts.

If you want to have a conversation style script it would be fairly easy to write a script that displays the conversation through a series of huds and play the audio at the same time as the words appear on the screen. It would be vastly easier to accomplish than what I think your trying to do.
As youll read a script is a set of conditions and actions
:state=1,plrwithinzone=1:setposteffect=sharpen,state=2
In the above line the first part before the colon is the conditions which the engine checks to see if the are true.
another words the engine keeps checking to see if the player is in the trigger zone. If the player is in the trigger zone then the engine continues on with the script and starts executing the actions, in this case setting a post effet, and changeing to a different state, state=2
Kinda a simplified crash course I guess. Go to your scipt folder and open a script and practice following the script and understand what it's doing. Like a doorkey script would be a good one to look at.
You have to get into a certain state of mind to write them, because you have to think how the engine thinks, and do things in steps.
To get the tank to move.
Set a way point and lay down the path you want the tank to follow.
Place the tank at the begining of the route.
in the tanks settings change it to dynamic
change the main to people/follow
adjust the speed as desired.
make sure the the "isimobile" field is set to no
That should do it.
