|Boolean values: yes or no, true or false, 1 or 0
Can be set to 'yes' or 'no' and specifies whether or not this BuildingType can produce a replica of the current unit being produced at a Factory=. This is used only on the Cloning Vat in Red Alert 2.
Note that when setting this on a structure (let's call it 'Structure A') which has Factory=InfantryType set aswell, the structure will produce infantry like normal barracks, but these infantry units will not be cloned by any instance of Structure A if they are produced by an instance of Structure A. Infantry units will however be cloned by all instances of Structure A owned by a given player if that player produces these units in an instance of another type of structure (such as normal barracks). An interesting effect could thus be achieved by giving one side (or country) a building for infantry production which has Cloning=yes set. The side (or country) could produce infantry the normal way, however upon capturing or building another side's Barracks, all of their own barracks would function as Cloning Vats for every infantry unit produced in that other sides's Barracks.Wether instances of a structure type with Cloning=yes clone infantry that has been produced by an instance of another structure type with Cloning=yes still requires testing.
