If you haven’t preordered the game already, we have some great incentives for you to do so. Two exclusive multiplayer units are available only for those who preorder or purchase the game via PSN: The British SAS with the AS-50 BMG sniper/anti-material rifle and the German KSK with the F2000 assault rifle. You can find these pre-order programs at retailers like Best Buy, GameCrazy, GameStop, Amazon.com and other participating retailers. Fans who purchase their copy of SOCOM: U.S. Navy SEALs Fireteam Bravo 3 from the PlayStation Network within the first 30 days of launch will receive the pre-order Special Forces."
