Lionel Jackson, the older African-American victim, explains to Logan and Briscoe in the hospital that he knew to duck and run for cover when he saw the shotgun due to his WWII service in the 761st Battalion at Omaha Beech on D-Day. The 761st Tank Battalion was a unit in World War II and was primarily manned by African-Americans (the U.S. Army did not desegregate until after the war) however it was not deployed for action until November 1944, five months after D-Day.
