U.S. soldiers, sailors, Marines and airmen march from the Arc de Triomphe to the Place de la Concorde in Paris, July 12, 2017, during a rehearsal for the Bastille Day military parade. The United States led the parade to commemorate the centennial of U.S. entry into World War I and the longstanding partnership between the United States and France. For the 173rd year in a row, Soldiers of the New York Army National Guard’s 1st Battalion, “Fighting 69th” Infantry Regiment, marched at the head of New York City’s Saint Patrick’s Day Parade — the largest in the world.
