Chinese Naval Infantry

Strategypage discusses the expansion of the Chinese marine forces (to 40,000 with 7 brigades and a special forces brigade).

Note that America has about 200,000 active Marines with about the same number of brigade-like regimental combat teams. The United States Marines are a fighting force with depth while the Chinese force is more like shock troops.

While the Chinese marines aren't necessary for amphibious invasions (they have army divisions trained for amphibious warfare, like America used in Europe during World War II for all the landings, recall, as well as in the southern Pacific offensive), the additional Chinese marines could be used for spearheading a joint invasion force (of Taiwan, for example) in addition to independent smaller operations in the South China Sea or East China Sea--or abroad in peacetime missions.

So yeah, they should be tracked when they move around.

UPDATE: I corrected the text to note 7 brigades. I misread the post.
