Flash & HeyJoe: I hope & assume you're correct w/ your info. I'm 25 yrs out of the cockpit, seldom have the opportunity to talk to current fleet aviators & only know what I read in AW&ST. Maybe "Fresh" above can clarify some of this. The Aviation Week article I read about the Cope India exercise was that the Sukhoi's waxed the AESA-equipped F-15's & the IR gear played a big role. The Russians are famous for great scientists but lousy engineering & maintenance.
The Indians did quite well, better than anyone gave them credit for before the excercise. But we did not bring everything we have to the fight, and you generally heard only one side fo the story, so take it all for what it is worth.
Several things to note about the Indians. They have had the unique experience of creating their own tactics for almost the entire history of their air force. They have taken a mix of Russian and western tactics and added a lot of their own original ideas into the mix, resulting in a unique set of training and tactics that you don't find elsewhere. That is unlike our NATO partners that use mainly the same tactics across the alliance, along with our other major allies that use similar tactics formulated by the US over the years. The USSR spread its own brand around the world to their allies and client states, resulting in two broad way of doing things. While India has gotten the vast majority of its arms from the USSR, they never subscribed to the Russian way of business and as a result their tactics were a big unknown to most of the rest of the world (much less so since Cope India, they have taken part in an increasing number of excercises since then with the Brits and others). Hence a big part of the surprise at Cope India, the first major aerial excercise we have done with them in a very long while (if ever?), was the new tactics.
Another thing to note is that while they fly the Su-30, as Fresh pointed out they fly their own version, the Su-30MKI. A big difference between this and the Russian Flankers is that the MKI has a lot of French and Israeli elctronics/avionics, which are slightly more dependable than the Russian equivalents. And while they might have a very capable IRST, it is by no means a replacement for radar. It is a lot easier to find someone when you have briefed it with the guy in the same room before the flight, different story when you have the whole sky to search.
Finally, while AWS&T is an excellent source of info, I think you may know that it is not the be all to end all. They, as do many in the foreign/international press, like to gloat over any supposed weakness or foible of the US and quickly pounce all over it. Not only that, it gave the Indians something to crow about, which they seemed to do with some glee (who wouldn't?). So take some of the press reports with a grain of salt. Though as always, there is a lot of truth to them. Clear as mud?
