The Czechs are currently developing a new type of ERA (Explosive Reactive Armor) for APCs and tanks. What makes it special is the ability to destroy incoming RPG's and ATGM's before they reach the tank itself. Another beneficial feature is the possibility to use Slat armor (Cage armor) in conjunction with Fire Shield, as they would not interfere with each other as the "standart" ERA would. Theoretically, this system would not limit the use of other defensive countermeasures, however no other reports were available at the moment and it is still being developed. The video shows the effectivity against RPG-7. The true defensive capabilities or if the system would be able to defeat tandem warhead anti-tank weapons is currently unknown.Source: www.ceskatelevize.cz/ct24/domaci/220993-armada-vyviji-ohnivy
