The AIM-9M Sidewinder is an American short-range air-to-air missile, a much more modernized and improved variant in the AIM-9 Sidewinder lineup developed in the 1950s. Most models of Sidewinder missile make use of infrared homing systems, including the AIM-9M. The AIM-9M itself is an improvement over the AIM-9L, which itself was a major step in the direction of creating a more capable all-around anti-air missile.
The AIM-9M Sidewinder is a secondary weapon for American aircraft featured in Battlefield 2. It is the statistical equivalent of the AA11 Archer, which is used by Middle Eastern Coalition and People's Liberation Army jets as their respective secondary weapon, and does 100 damage with a force of 10 and an explosive radius of 4. It is also the missile projectile used by the in-game RIM-162 Evolved SeaSparrow Missile system on the USS Essex (LHD-2), evidenced by the in-game file.
