Women have served in the United States military for over two hundred years. Some female veterans perceive themselves as discriminated against by their male counterparts and, as such, women who have served in the armed forces have sometimes been known as "the invisible veterans". Women were not fully recognized as veterans until after WWII, and prior to this they were not eligible for VA benefits. The current percentage of U.S. Veterans who are women is more than 8 percent. Women make up nearly 11.6 percent of OEF/OIF/OND Veterans. A tri-state (Washington, Idaho, Oregon) women veterans conference in Pendleton, Oregon, in April 2008, attracted 362 women veterans, according to the "East Oregonian" newspaper. A growing number of states are recognizing June 12 as Women Veterans Day, either through proclamation or legislative action.
