  Depending on the multinational force arrangement in-theater, Army engineers may control or work
  closely with engineers from other nations. Command and support relationships for multinational engineer
  forces are established to enable unity of effort. Providing adequate U.S. engineer liaison officer (LNO)
  support (linguist support, communications equipment, and transportation) is critical to this process.
  When projecting the force, the initial engineering capabilities in-theater can employ a mix of HN,
  contracted, and multinational capabilities. As Army engineers deploy into a theater, they may be joined by
  multinational and joint engineers. When coordinating multinational engineer plans and operations, the theater
  army engineer staff should consider the joint considerations that are addressed in JP 3-34 and the following:
  * Requesting the latest information and intelligence concerning the HN or multinational engineer
  structures and logistics requirements.
  * Requesting the latest engineer intelligence data from the HN or deploying multinational engineer
  elements to help identify force projection theater army engineer requirements and enemy
  engineering capabilities.
  * Requesting HN geospatial data, including terrain, feature, cultural, demographic, explosive
  hazards, obstacle, and other available geospatial data.
  * Establishing multinational engineer staff links between the theater army, HN, and multinational
  engineer force staff sections through the JTF or combatant commands engineer staff and
  headquarters.
  * Providing NATO multinational C2 with the NATO operation order (OPORD) format and the
  NATO decisionmaking process.
  * Providing necessary Army engineer LNO support.
  * Developing the multinational task organization relationships that enhance HN and multinational
  engineering capabilities following the deployment of Army engineers.
  * Assessing the need for HN and multinational engineer support following the arrival of Army
  engineer units in-theater.
  * Determining if multinational engineer units need augmentation from Army engineer units.
  * Developing procedures for Army engineer units to support multinational engineers with additional
  Class IV construction materials and engineer equipment.
  HOST-NATION CONSIDERATIONS
  In a forward-deployed theater, the theater army identifies wartime facility and construction
  requirements for the Army as part of the deliberate war planning effort. The planning module in the joint
  construction management system (JCMS) is used to identify construction requirements. Construction plans
  may also be requested from one of the USACE Centers of Standardization to site-adapt existing drawings.
  Subsequent analyses further refine construction requirements and provide a basis for—
  * Force structuring.
  * Procurement.
  * Lease provisions and HN agreements.
  The product of these analyses is the engineer support plan (ESP). The goal is to reach HN support
  agreements in peacetime to provide maximum facilities within the theater. Advanced planning and the
  commitment of resources by HNs reduce the early lift requirements needed to support reception, staging,
  onward movement, and integration (RSOI). Written agreements with HNs regarding support items foster an
  understanding of the assistance levels and increase the likelihood of execution. Engineer support from the
  HN usually involves providing—
  * All available geospatial data.
  * Land.
  * Facilities.
  * Construction support.
  * Manpower.
  * Equipment.
