This building allows Chinese generals to access the most advanced Chinese weapons and tactics in the field. Its primary role is akin with Battle Lab or Tech center. A commander requires a Propaganda Center in his base of operations to access the Nuclear Missile Silo, Overlord Tank and a number of other units.
On the left side of the Propaganda Center, there is a yellow sign, which has the Chinese words "提防偷鞋" (Beware of thieves stealing shoes) written on it. This is very strange and awkward considering that a place where highly classified military information is stored can be infiltrated by regular thieves who steal shoes.
