Battlefield 2's first expansion pack, Special Forces, first began its development sometime during or shortly before the release of the original Battlefield 2 by DICE Canada: Battlefield producer, Mike Doran, commented in August 2005 that "The truth is that work on Battlefield 2: Special Forces began several months ago.". It was officially announced on July 14, 2005 and released on November 21 of the same year. The focus of the development was infantry-based combat as opposed to vehicle-centric combat from the original. As such, most of the additional content in the expansion pack can only be used by or for infantry. Maps of Battlefield 2 Special Forces are: Devil's Perch:U.S.M.C. M.E.C. Ghost Town:SAS, Spetsnaz Mass Destruction:Spetsnaz, Rebels Night Flight:SAS, Insurgents Surge:Spetsnaz, Rebels Warlord:SAS, Insurgents
Players play in eight maps (six of which can be played in singleplayer) with ten more vehicles such as the AH-64D Apache and Mi-35 Hind, though all jets have been removed. In addition to these new contents, players have access to new equipment such as night vision goggles, tear gas, gas masks, zip lines and grappling hooks which can alter gameplay. There are eight more small arms weapons available such as the G36K/E and FN SCAR L/H and several weapons from the original are replaced. The expansion offers more awards in the form of badges, ribbons, and medals that players can earn. Finally, many of the weapons from the expansion may be used in the original Battlefield 2.
