I had seen this 5-part series on TV almost 20 years ago, and still remember much of it.
It provides a background to the Red Armed Forces of China, as well as some history (distant and recent as per the time of the filming).
The filmmaker had unprecedented access to each branch of their forces, revealing much about such a secret and mysterious (to the 'west') entity (much like North Korea still is).
With China today evolving into a contemporary super power, you can see how prescient the subject matter of the film was, and with China's financial rising, you can extrapolate how much more their armed forces must have evolved...
If only it were available for viewing today...
