The embassy compound is by far the largest the world has ever seen, at one and a half square miles, big enough for 94 football fields. It cost three quarters of a billion dollars to build (coming in about $150 million over budget). Inside its high walls, guard towers and machine-gun emplacements lie not just the embassy itself, but more than 20 other buildings, including residential quarters, a gym and swimming pool, commercial facilities, a power station and a water-treatment plant.
Yet the embassy is turning out to be too small for the swelling retinue of gunmen, gardeners and other workers the State Department considers necessary to provide security and "life support" for the sizable group of diplomats, military advisers and other executive branch officials who will be taking shelter there once the troops withdraw from the country.
The number of personnel under the authority of the U.S. ambassador to Iraq will swell from 8,000 to about 16,000 as the troop presence is drawn down, a State Department official told The Huffington Post. "About 10 percent would be core programmatic staff, 10 percent management and aviation, 30 percent life support contractors -- and 50 percent security," he said.
