Military: Electronic warfare: From RF to EO: Electrooptics gains on RF and acoustic technologies in electronic deception, jamming, and neutralization

The importance of electronics in modern combat was dramatically demonstrated in the October 1973 Middle East war, when the Israelis used U.S.-developed chaff rockets to evade about 50 Russian Styx antiship missiles fired at them by combined Arab forces. In 1967, without such electronic warfare (EW) countermeasures, the Israelis lost a destroyer, the Eilat, and a merchant ship, both of which were sunk by Styx missiles.
