Bob Kuzmicki (366th AMS 7/69 - 7/70) taped these audio files while at Danang. They are recordings of the sirens and warnings over the base speakers during rocket attacks.

You will need an mp3 audio file player to play these files. The windows and other operating systems should be able to do this. If you can't play them, let me know.
 

Russell Harrell (366th Security Police, 1969) taped this rocket attack. This is a wav file.
