"Scud"is the codename for a series of tactical ballistic missiles based on a late 1950s Soviet Union design. The mass-produced R-17 Elbrus "Scud-B" went into service in 1964. It can carry a payload of a thermonuclear, chemical, or conventional warhead to a range of over 180 miles. "Scud-Bs" are usually loaded on a Transporter Erector Launcher (TEL) vehicle allowing the missile and its launch system to be quickly relocated. After arriving at a new location, a "Scud" can be readied for launch in 60 to 90 minutes. With around 7,000 built "Scud-Bs"were used by over 30 countries and saw combat in several wars, Several countries continue to use "Scud-Bs" or foreign built versions of the missile.

 

During Operation Desert Storm the Iraqi Military deployed Soviet built "Scud-B" missiles and Iraqi produced Al-Hussein, and Al-Hijarah versions of the "Scud-B" design. During the war Iraq launched a total of 88 "Scuds" at targets in Israel and Saudi Arabia. One struck a U.S. Army barracks in Dharan, Saudi Arabia killing 28 American soldiers.
