New enemies (the Stealth Tank and Stealth Tank Prototype)

This video details a new enemy that the fearless hero and bringer of freedom to America (the player) will have to face.

The Russians have ushered in a new breed of warfare and have cracked the code for stealth technology. 

This video shows two two enemies the stealth tank which can turn completely invisible for fairly long periods of time and only needs to reappear right before shooting .

The second enemy is the stealth tank prototype which also has cloaking but for less time and requires a special generator to do so. However that generator can be destroyed making it easier for the tank to be defeated.
