  ENGINEER SUPPORT ACROSS THE RANGE OF MILITARY
  OPERATIONS
  While violence varies across the range of military operations, the magnitude of requirements for
  engineers may remain consistently high from peace through war. This demand results in the application of
  the engineer disciplines to provide a menu of actions available to support military operations.
  Engineer requirements to support peace during military operations may include geospatial engineering
  support to provide a clear understanding of the physical environment. Military engagement, security
  cooperation, and deterrence activities sometimes require large numbers of forces. These forces need
  infrastructure, facilities, LOCs, and bases or base camps to support sustainment. Even in areas with well-
  developed existing infrastructure, significant engineer effort is required for the planning, design,
  construction, acquisition, operation, maintenance, or repair necessary to support operations in-theater.
  Assistance in response to disaster and humanitarian relief usually includes significant engineering challenges
  and opportunities to affect the situation immediately and positively.
  Engineer activities to support war during military operations require support for ground combat (or the
  possibility of ground combat). Engineers and other supporting units integrate with fires and maneuver to
  assure the mobility of friendly forces, alter the mobility of threats, and enhance the survivability of friendly
  forces. It also involves the significant challenges associated with sustaining the operation.
  During transitions between peace and war, engineers are often required to improve stability through
  projects that develop infrastructure and create or improve HN technological capacity. There may also be
  requirements to provide specialized engineer support to other agencies. The USACE uses the Foreign
  Military Sales program to support intergovernmental relations and to enhance capacity through construction.
  Engineers involved in unconventional warfare help overcome challenges to the commander’s ability to move
  and maneuver freely, protect the forces employed, and sustain the operation. Other requirements include
  directly impacting threat freedom of action and improving stability.
  ENGINEER ACTIVITIES SPANNING THE LEVELS OF WAR
  The challenges of planning, preparing, executing, and continuously assessing operations within diverse
  theaters are numerous and varied. The engineer staff must be involved in the operations planning process at
  each level of war (strategic, operational, and tactical). (See ADP 3-0 for additional information.)
  Understanding the challenges and opportunities identified from an engineer view equips the staff with
  relevant information to form a more comprehensive understanding. The omission of engineer considerations
  at any level may adversely affect the effectiveness of the operation. Engineer support to operations must be
  synchronized from the strategic level to the tactical level.
  STRATEGIC
  Engineer planners must determine the means, ways, and ends as part of a joint force to prevent, shape,
  and win decisively. Activities include planning the right engineer force with the right mixture of capabilities,
  engineer policy, and doctrine development in place to mobilize, deploy, employ, sustain, and redeploy forces.
  Engineer activities at the strategic level seek ways to contribute to preventing, shaping, and winning by
  setting conditions for decisive action. Engineers conduct force planning, develop engineer policy, and support
  campaigns and operations, focusing primarily on the means and capabilities to generate, deploy, employ,
  sustain, and recover forces.
  Additionally, infrastructure development is a critical aspect of enabling and sustaining force
  deployments, and it places a heavy demand on engineer requirements. Engineers at the strategic level advise
  on terrain and infrastructure, to include—
  * GI&S.
  * TGD management.
  * SPOD.
  * APOD.
  * Force generation.
