Mar. 23, 1943 - During World War II, massed fires from II Corps Artillery at the Battle of El Guettar destroyed 30 German tanks. The ability to mass fire of artillery and tank destroyers came after a change to artillery procedures after the U.S. loss at the Battle of the Kasserine Pass in February. After that loss, serveral changes were made, and the II Corps Artillery was given more flexibility in responding to fire requests. At El Guettar, all artillery units within range of a call for fire were free to fire the requested mission.
1983 - In an address to the nation, President Ronald Reagan proposed that the United States embark on a program to develop antimissile technology that would make the country nearly impervious to attack by nuclear missiles. Reagan’s speech marked the beginning of what came to be known as the controversial Strategic Defense Initiative (SDI).
