PLA offers technology in fight against smog

The People's Liberation Army has come up with a new way to fulfill its mission of protecting the Chinese people. In this case, its adversary is tiny and insidious but at the same time, expansive and wide ranging.

The foe is smog, which currently is covering North China in a gray blanket.

While working in laboratories and testing grounds to develop military technology, PLA scientists have found their tools can also be put to civilian use.
