Ready for the last battle? You better be. It's appropriately tough and will test all your skills as a commander. The SEALs dropped in should eliminate the power plant first, then eliminate all the leftover Soviet structures. This is somewhat an annoying defensive postion because the base is vulnerable on all sides. Build plenty of patriot missiles and prism towers to defend this area as you will be defending as much as attacking here. Capture all the derricks around as well as the airport so you can get the free troops every now and then. This isn't easy, but if you handle it like a normal base assault you will be fine. I had an interesting chain of events with the nuclear reactors of the Soviets in this mission. I had captured the two on the eastern side of the map and had damaged their base quite a bit by repeated prism/mirage tank assaults. I used 4 chrono legionnaires, jumped two on the western and two on the eastern side of their base. Once they were out of the delay I jumped them again next to the nuclear reactors. One for each of the four reactors, when they began using their chrono gun on the plants, the entire base's power went offline. The last phase of my assault went flawlessly as a result. There isn't a whole lot of information I can give you on how you should finish this yourself, but I can give a few tips here:
