If you would like to honor the military families of the fallen of the Chattanooga shooting on August 15, 2015 the Memorial Service is open to the public. The first 8,500 people will be able to go through screening and attend. 

The ceremony starts at 2 pm and the doors will be open earlier to give everyone enough time to be screened and also seated.
