在美军的综合防空体系中,低空防空是重要的环节。在陆军部队投入作战时,低空防空用来掩护部队免遭敌低空攻击,保证地面部队的自由机动;还要阻止敌方对已方战场的侦察,协助打赢信息战。低空防空的主要目标是巡航导弹、无人机,以及低空飞行的固定翼飞机和直升机。为了完成上述低空防空任务,美陆军现装备有以“毒刺”防空导弹为基础的三种近程防空武器系统——供轻型和特种部队使用的“毒刺”便携式防空系统;抗击敌人侦察,掩护机动部队和重要设施的“复仇者”机动防空系统;以及用于 In the U.S. air defense system, low-level air defense is an important link. When the army troops put into combat, the low-altitude air defense was used to shield the troops from low-altitude attack by the enemy to ensure the free movement of the ground forces; and to stop the enemy from reconnaissance on the battlefield already side and help win the information war. The main targets of low-level air defense are cruise missiles, unmanned aerial vehicles, and fixed-wing aircraft and helicopters flying at low altitude. To accomplish the above-mentioned low-altitude air defense mission, the U.S. Army is now equipped with three short-range air defense weapon systems based on Stinger anti-aircraft missiles - the “Stinger” portable air defense system for light and special forces units; the anti-aircraft reconnaissance, Avenger mobile air defense systems to cover mobile units and vital facilities;
