The American Spy Satellite network is the world's most extensive and advanced. During the GLA War, American commanders are granted access to use Spy Satellite to survey the battlefield and observe enemy troop movements. Every 1 minute, American commanders may link to the Spy Satellite at the Command Center and select an area on the map to reveal. The Spy Satellite will reveal the area and all enemy troop movements there to the commander for about 15 seconds, including any stealth units.
