If New to sound Files.
You use them in the Mission Editor after you put the sound file in a folder for the editor to find.
A Simple way is to create a folder like I did called "Mission Sound Files" inside the 
C:User\*YourUserName*\SavedGames\DCS\Missions Folder. Put all sound files you get in this Folder.
I will not teach how to use the Mission Edit Program so this is the end for me.
This sound file is in the *.ogg format
Playtime is just over 1 hour.
Rated R for 18 and over because it is REAL life Combat Radio Chatter from Vietnam and has
Dirty words in it so do not use it if Children are around.
