  Figure 4-1. Mail flow
  4-77. The initial standard for the JOA is restricted mail service, including restrictions imposed by the
  host-nation. Mail is limited to first-class mail items, including audio and video media, weighing 13 ounces
  or less. The commander may lift restrictions and permit parcels as the JOA matures, more postal personnel
  become available, and the theater ground transportation and airlift logistical systems mature.
  4-78. It is important to note that organic transportation assets within units performing postal missions are
  structured to move assigned personnel and equipment, not mail. The postal operations management network
  must coordinate all inbound and outbound mail transportation requirements with transportation managers at
  each level of command, from the MMT to the brigade mail delivery point. Ultimately, effective mail
  movement requires assured military, contracted, and/or host-nation transportation support. The standard mail
  delivery time from CONUS to the JOA MMT is 14 days’ contingent upon a developed transportation network
  and METT-TC.
