Battlefield 2: Armored Fury is the second booster pack released for Battlefield 2 and was released on June 6, 2006. It added 3 new maps, as well as two new vehicle classes: attack jets for close air support and reconnaissance helicopters that operate as a mobile UAV. The booster pack has the USMC defending U.S. soil from invasions from the PLA and MEC. Operation Midnight Sun features the Chinese landing at the Alaskan port Valdez where they are trying to secure much needed fuel from the pipeline. Operation Road Rage is a MEC vs. USMC map, where the MEC are using US Highways to transport units to industrial areas. Operation Harvest sees the United States trying to stall the MEC en route to the capital from the northwest, being blocked in a Pennsylvania Dutch farm, while waiting for reinforcements. New vehicles include Attack or Close Air Support aircraft such as the A-10 Thunderbolt II, Su-39 and the Nanchang Q-5 as well as new light utility helicopters such as OH-6 Little Bird, EC-635 and the Z-11. As well as the addition of new helicopters and planes, DICE also added the Muscle Car and Semi Truck.
