The EMP Mines are a hidden defense used by China which essentially act as a deterrent for both infantry and vehicles.
EMP Mines are simple defenses used at choke points or other important locations. Though the blast of a Mine can kill or heavily injure infantry, its most prominent feature is that it disables enemy vehicles for a large amount of time. This gives a Soviet commander either more time to set up defenses, or to trap and then destroy helpless enemies. Placing an EMP Mine on a single cell will result in 4 more appearing nearby, wherever free space is available.
In Combustion, Chinese left some of their EMP Mines on the southwestern coast, and they are retaken by European enemies.
The EMP Mines first appears in Unshakeable as a buildable structure.
