This is a Chinese game made by Giant Network Technology Co. as a recruiting and training game for the PLA (People's Liberation Army). As with most stuff in China involving military matters, they aren't very forthcoming with lots of details, but from various descriptions I've heard, it sound like the "enemy" is going to be the US Army.

Youtube Videos from Chinese news station CCTV that contain news reports on the game are here:

Here's a screenrecording video showing the game being played (presumably either from a soldier recording the gameplay in violation of Chinese military secrecy policies, or a civilian playing a pirated copy).
