Larry Johnson wrote an excellent review. Here is one excerpt.
First, from the last year of WW II until now the US has always fought with air superiority and never faced a comparable air force. Russia changes that calculus. Not only does it have a robust combat air capability that rivals anything the United States or NATO can put in the air, the Russians have the largest interconnected air defense system in the world. Five systems that are all data linked according to Karber. And this was the status quo from four years ago. Russian has made additional significant technological gains on this front.
Read the whole thing by following the link to Larry's blog. Netcentricity rules in this case. Both main Russian combat helis Ka-52 and Mi-28 have data links to ground units which designate targets. This is apart from having links between each-other.
