If multiple missiles are shot simultaneously at the vehicle, or if certain missiles are used (which Hezbollah posesses) it creates great vulnerability for this system. For point one, the system cannot protect against two simultaneous hits at the same spot shortly after one another, and for the second point it cannot protect against two-or three stage-type antitank rockets. Suck rockets are designed to absorb the "first" and possible "second" spit of "metal shreds" that the tank fires at the projectile but still maintain the main central charge that can penetrate active armor and damage the hull, and cause an all out explosion and destroy the tank if fired at the correct spots. Furthermore, i think mines will be a much greater hazard for IDF tanks in any future wars than antitank weapons.
