Saddam's army, prior to the invasion did not number one million, not in anyones dreams.
"Weapons and manpower remain at about the same levels as immediately after the Gulf War, according to London's International Institute for Strategic Studies, which publishes annual detailed estimates of military strength worldwide.
Across the board, the Iraqi military is smaller - down 618,000 from a 1990 high of 1 million active-duty forces; down 2,800 main battle tanks from 5,500 in 1990; down 1,500 towed artillery pieces, half the 1990 number; and down 197 fighters and fighter-bombers from 507 in 1990. These figures largely agree with separate analyses conducted by the Pentagon's Defense Intelligence Agency.
In addition to the destruction wrought by the Gulf War, Iraq has chafed under an international embargo on arms imports and oil exports, cutting off easy access to a country that before 1990 bought $2 billion to $3 billion in weapons every year. Iraq has faced pressure as well from the United Nations Special Commission on Iraq to eliminate its weapons of mass destruction."
