I also want to ask, why I can't launch any attack to a country that has invaded mine?
I'm a GDI member, and I think I can attack a country that has invaded mine, right?
You can attack anyone with some attacks. Standard strike, planned strike. Other attacks, the more nasty ones, are forbidden by GDI unless the GDI hymen has been broken by multiple standard strikes, planned strikes, or black spy ops #tmyk
