Airmen from Ellsworth Air Force Base stand post during the Veterans Day parade in Rapid City, S.D., Nov. 11, 2013. Veterans Day was originally known as Armistice Day and symbolized world peace and the end of one of humanities greatest conflicts - World War I. It wasn’t until 1954 and several years after World War II and the Korean War when congress decided the holiday would honor servicemembers who fought in all wars.
