3-17: Sustainment

Previous: 3-16: Reserve

3-17. The sustainment mission in an area defense requires a careful balance between establishing forward supply stocks of petroleum, oil, and lubricants (POL); barrier materiel; and ammunition in adequate amounts to support defending units and having too many supplies located in forward locations that they cannot be rapidly moved in reacting to enemy advances. All suitable POL, barrier materiel, construction equipment, and laborers can be lawfully obtained from the civil infrastructure reducing the defending unit’s transportation requirements. Likewise, maintenance and medical support with their associated repair parts and medical supplies also must be forward deployed.
