The SAM system, which stands for Surface to Air Missle is a new unmanned weapons that showed up in Grand Theft Auto: San Andreas. Unfortunately it cannot be used by the player, and is rater used against him/her. They are found in the restricted zone on San Andreas and will fire guided missles at any plane that flies over the base. The launchers can be temporairly destroyed; and will respawn once the player is far enough. Caution must be taken when flying over these as they will take down any helicopter; and all but the fastest planes. The Hydra has launched countermeasures (flares) that can deter the missles.
