King Khalid Military City (KKMC or "Emerald City") at Al Batin, Saudi Arabia was built to defend the north-eastern border of the Kingdom of Saudi Arabia. Designed for an army division of three brigades, the city had a design population of about 65,000 people. In the 1960s and 1970s, U.S. Army and Air Force engineers designed and constructed several Saudi bases, including Taif, King Khalid Military City and Khamis Mushait. History shows these bases and support facilities provided the needed infrastructure to help absorb a deployment of the size and speed of Desert Shield.
