6. The Iranian Army, mobilized and numbering upwards to 15 million men (CIA World Factbook) pours across the border with Iraq, vastly outnumbering US 130K troops.
15 million? Effectives or including the twice yearly militias? Iran doesn't have the supply capacity to mobilize and support 15 million, or anywhere near that many troops. This also strongly ups the ante, and increases the likelyhood that the US would use tactical nukes to wipe out the Iranian units massing across the border.
The 15 million listed in the CIA World Factbook is the estimated number for the statistic of "manpower
fit for military service". This is not the total size of the Iranian army; it is simply the number of people who meet the physical requirements to be part of the army. This statistic for the United States is 109,305,756 men and women. Unless that poster thinks that the American army has over 100 million people in it, perhaps he should do his homework regarding what "manpower fit for military service" means.
