The American Civil Liberties Union filed a suit Tuesday challenging the policy that keeps women from thousands of ground-combat positions. “Nearly a century after women first earned the right of suffrage, the combat-exclusion policy still denies women a core component of full citizenship—serving on equal footing in the military defense of our nation,” the suit reads. The ACLU says that women are currently barred from more than 230,000 military positions. A spokesman for Defense Secretary Leon Panetta said that he is still “very committed to examining the expansion of roles for women in the U.S. military and he’s done so.”
