Spike MR (formerly known as GILL) is a lightweight (less than 13.0 kg) Medium range weapon,  designed to offer the infantry an effective anti-tank and precision attack capability at ranges from 200 m to 2,500 meters. A system, comprising a missile and launcher weighs less than 26 kg. A typical Gill anti-tank team include two soldiers, one carrying two missiles and the other - the tripod and fire control unit. Further reduction of weight is enabled by utilizing the missile's imaging seeker for target acquisition, which eliminate the need for a dedicated thermal sight which weighs 4 kg. However, such a sight improves the target acquisition range of the system, especially at long range. The system can deploy and be ready to fire within 30 seconds. Gill can be reloaded and be ready to fire again within 15 seconds. The missile is safe to operate from enclosed spaces, which is an essential capability for combat from protected firing positions and in urban warfare. The missile uses a dual mode IIR/CCD seeker to locate the target and lock on it from the maximum operating range. Further enhancing the troop’s safety is the “Fire-and-Forget” operating mode. The missile uses a tandem warhead to defeat even the latest advanced armor.
