  SECTION II – POSTAL OPERATIONS
  4-56. The MPS is operated as an extension of the USPS as authorized by 39 U.S.C. § 406 and IAW the
  domestic agreement between DOD and USPS which is known as USPS Publication 38, Postal Agreement
  between the United States Postal Service and the Department of Defense. The DOD and the USPS agreed to
  furnish mail services to the military as close as practical to that provided to the civilian population in the
  United States.
  4-57. Postal operations have a significant effect on the morale of Soldiers and their families. General George
  Patton preached to his unit commanders after Operation MARKET GARDEN (October 1944) the critical
  necessity of maintaining morale. General Patton stated, “This required getting the Soldiers the best food
  available, including as many hot meals as possible, and, even more important, ensuring that mail from home
  reached every Soldier rapidly and regularly.” Just as Patton had demanded the utmost of all unit commanders
  in combat, now he called on them to move heaven and earth to get fresh food when, supposedly, only C and
  K rations were available, and to prod their G-3s into giving mail the highest priority.
  4-58. Depending on the combatant commander's priorities, mail service could be available within the first
  30 days of operations. Postal operations consist of a network of military HR organizations. Efficient and
  effective postal operations require dedicated postal organizations with trained postal clerks and HR leaders
  knowledgeable of postal operations laws, regulations, and procedures needed in the execution of providing
  postal services globally to deployed units and personnel. There are two types of postal mission support:
  general and direct support. General support missions are normally assigned to an MMT but can also be
  assigned to a MPO supporting on an area basis. Direct support missions are normally assigned to an MPO
  but can also be assigned to a MMT when multiple MMTs are assigned to a theater due to size and dispersion.
  Mail delivery to DOD patrons is through either an MPO or a unit mailroom for both personal and official
  mail. Refer to ATP 1-0.2 for more detailed information on processing mail and providing postal services.
  PROPONENCY
  4-59. The Army’s functional proponent for the postal operations management system is The Adjutant
  General Directorate, HRC. The Adjutant General is also the executive director for the MPSA. The DOD
  4525.6-M and AR 600-8-3, Postal Operations, provides mandatory policy and procedural guidance for postal
  operations management during military operations. Statutory requirements are found in United States Code
  and Code of Federal Regulations listed by topic in the above references.
