Following the terrorist attacks on Sept. 11, 2001, The American Legion resurrected the tradition of displaying the Blue Star Service Banner, reflecting the pride and sacrifices made by families of those serving on active duty during times of war. While the tradition dates back to World War I and was heavily observed during subsequent wars, American Legion posts around the country have now given banners to families of departing troops engaged in the Global War on Terrorism and supported the troops with morale and welfare packages, many adopting entire units on deployment.
