The AIM-9M Sidewinder is an American short-range air-to-air missile, developed in the 1950s. Most models of Sidewinder missile make use of infrared homing systems, including the AIM9M. The AIM9M itself is an improvement over the AIM9L, which itself was a major step in the direction of creating a more capable all-around anti-air missile.
The AIM9M 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.
