The U.S. Army’s decision was influenced by the system’s light weight and ability to fire interceptors without shock, as well as an attractive price-tag, Zafir said. He also praised its ability to defend against RPGs, rockets, and anti-tank missiles. The system has been successfully tested against a wide variety of threats including rocket-propelled grenades, anti-tank guided missiles and tank-fired HEAT ammunition and kinetic energy penetrators.
IRON FIST employs a sophisticated, multi-sensor early warning system, utilizing both infrared and radar sensors, providing the crew with enhanced situational awareness and early warning from potential threats. Upon a threat warning, the modular system employs the multi-layered defenses, comprising electro-optical jammers, Instantaneous smoke screens and, if necessary, an interceptor-based hard kill Active Protection System (APS).
IRON FIST APS was also selected by the Israel Defense Forces (IDF) as the Active Protection System designed to protect the Namer heavy infantry fighting vehicle."
