There was a show on TV in the late 80s to early 90s, it was a war show. It was not Tour of Duty, it was something else. All I remember from the prelude is a Sunset at the end of it. The sunset was wavy looking because of the heat. I want to say that the title has one of these words in it... Sun... China... Rising or something of that nature.

Hi Tarabare,
I think the show you are looking for is "China Beach" which starred Dana Delaney.
I hope this helps. Take care. :)
