Nevertheless, the Soviet Navy achieves an advantage by occupying Iceland, taking control of the NATO airbase in Keflavík and ensuring command of the strategically important GIUK gap. U.S. Air Force lieutenant Mike Edwards escapes the attack and hides behind enemy lines, serving as a scout for NATO forces. The Soviet Navy also attack several resupply convoys from North America as well as a NATO carrier battle group in the North Atlantic, causing severe losses to the other side. Meanwhile, the Soviet Air Force engage in a fierce air battle over Norway and later secure a rocket launch site there, bringing key NATO radar and air stations in nearby Scotland within range of sustained air attack.
