Which of the following is NOT a responsibility of the MAJCOM Postal Representative?

The choice indicating that managing mail transport contracts is not a responsibility of the MAJCOM Postal Representative is correct. In the organizational structure of military postal services, the MAJCOM (Major Command) Postal Representative primarily focuses on overseeing postal operations, ensuring compliance with regulations, and managing the overall efficiency of postal services at their level. While they do coordinate and oversee general operations, the specific management of mail transport contracts usually falls under different logistical functions or specialized offices that handle contracts and transportation services rather than the direct oversight role of the Postal Representative. This allows the Representative to concentrate on the effectiveness and management of day-to-day postal operations and personnel deployment, which are far more critical to their direct oversight responsibilities.
