i have multiple questions to do so here they go:
1.It is possible to add energy(electrical) of a city?
2.It is possible to make a troop launch a missile?
3.It is possible to add unque troops?
4.It is possible to add a 'low power' advertence and keep the city in thw swadows?
1. please expand upon this... don't really undertand what you mean
2. yes, hoggy of the Blue Lotus team made there be rocket firing koreans if you mean have legionaires fire arrows or something then you need to change the model, change which animation they use and then change the EDU.txt file
3. yes... if you mean like the spartans (area specific recruitment) then yes, if you mean just making new units for each faction then yes also
4. same as 1

hope this helped... you should expand upon your questions though to make it easier for us
