The U. S. Army's new M1 9 binocular, which incorporates an unusual modular assembly concept for simplified maintainability, is currently being produced at the rate of 2,000 per month. In succeeding sections of this paper, the origin and development by the Army of the modular concept for this binocular are reviewed briefly and performance requirements are summarized. Following this, the manufacturing engineering approach and implementation developed and carried out by the Optical Division of Bell & Howell Company in producing the M19 binocular are presented.
