WEST POINT, N.Y. - The 121st football game between Army and Navy would be different, and that was obvious well before it started. Three hours before kickoff Saturday afternoon, during March On - the entrance in formation of the Corps of Cadets, followed by the Brigade of Midshipmen - the Cadets moved in relative silence, wearing their dress grays as the sound of the band echoed around Michie Stadium. The only people in the stands at the time were Department of Defense leadership.
