Create marker and create trigger script

Okay so I have this mission where a chopper gets shot down using setdamage 1. I want to create a marker on where the chopper crash site is. The name of the chopper is Heli1. Then I have a group of soldiers that I want to leave the players team and guard the crash site. How can this be accomplished. It might be possible to use the guarded by type trigger, but I don't really know.
