As many as 70 percent of the members of the Ohio National Guard could be called for active duty if the United States goes to war with Iraq. That’s according to Ohio Guard spokesman Major Neal O’Brien, who says the numbers will be similar to those called for World War two. That would represent the largest mobilization in decades. By comparison, less than ten percent of the National Guard force was mobilized for the gulf war. There have been no similar projections by the military reserves, but a 70 percent call-up makes sense for them too, according to retired Marine Colonel Allen Millett, a military historian for Ohio State University.
