The threat of rocket attacks have always been a part of Israeli history. Since the first massive missile strike against Israel during the Gulf War in 1991, Israelis live under a constant threat of rocket attack. Since 2001, nearly 13,000 rockets and mortars, an average of 3 attacks every single day, hit Israel, having been fired from Gaza. Since 1951, Israeli law has insisted that all residential or commercial properties be fitted with shelters. The IDF Home Front Command makes sure that Israelis have as much time as possible to find cover before a rocket hits — and recently, a new invention has changed the playing field of alarm systems.
