I am a Newbe to the game only owning the game for 5wks now. Defeating the USA levels on heard was not nearly has hard as the GLA levels. Thank you all for your posts. I find allot of your comments helpful in playing the game. I find not only good tips in this form, I also find a nest egg of good advise as well. On level 5 I had to use every resourse I could to win. The key I found was to keep destroying the USA power supply so the partical cannons would not work. Then I had to capture the four upper airfilds with supprise attacts. Allot more skill had to be learned here then on the other levels. I am now starting the China missions. I plan to defeat the General challange before I play online. I still have to learn how to better mannage each faction. KEEP UP THE GOOD IDEAS AND SHARE YOUR TACTICTS.
