Hi everyone, I do not have a strong background in Military science. Most of my knowledge of military equipment comes from computer games - obviously a very unreliable source of information. I have a few questions. I would be grateful for any help. 1. China is often portrayed as having a very advanced cyber capability. Is this true? Is it better than the US cyber capability or is it just a case of the rest of the world is well behind the US, and China is the only country that comes close to matching the US capability? 2. Is the Russian S400 system really the best AA system in the world or is this just an effective marketing strategy? 3. Do countries like Russia, China, North Korea, and Iran have any equipment that would be a match for western equipment? 4. Does Russia out do the United States in any military fields? Thank you for any help.
