stop the looping of the sounds

hey guys. i am making a map called the adventure of the unknown.
The units while playing everytime keep on talking everytime i click on them or move them. how do i stop that guys? Thank you.

open the unit editor for the units you dont want to talk, then scroll down to the stat 'sound - unit sound set' and set it to 'none'. They won't talk anymore.

This isn't a request by the way, it is world editor help. If you have any other help questions relating to the world editor then next time you should post it here
