Four days after the Iraqi invasion of Kuwait on 2August 1990, the 4th Battalion (Airborne), 325th Infantry was the Division Ready Force1 (DRF-1) and the initial ground force, as President George Bush's "Line in the Sand" speech to Saddam Hussein part of the largest deployment of American troops since Vietnam as part of Operation Desert Shield. The 4–325th INF immediately deployed to Riyadh and Thummim Saudi Arabia. Their role was to guard the royal family as part of the agreement with King Fahd to station troops in and around the kingdom. The DRF2 and3 (1–325 and 2-325 INF, respectively) began drawing the "line in the sand" near al Jubail by building defenses for possible retrograde operations. Soon after, the rest of the division followed. There, intensive training began in anticipation of desert fighting against the heavily armored Iraqi Army.
