  mass combat power and conduct continuous offensive operations for an extended time is key to the success
  of the offense. General engineering focuses on the requirements to sustain operations and ensure that
  commanders can commit follow-on forces decisively. Besides maintaining LOCs, engineers—
  * Develop or improve transportation nodes (airfields, ports, railroad terminals).
  * Manage real estate.
  * Provide and operate large-scale power-generation capabilities.
  * Find and drill for water.
  * Perform vertical and horizontal construction in support of the theater.
  * Validate and disseminate current geospatial information.
  Other Tasks
  Engineers also enhance protection through the execution of countering explosive hazards tasks. See
  ATP 3-34.20 for more information about countering explosive hazards. These include area and route
  clearance; specialized searches using engineer mine-detection dogs and patrol explosive-detection dogs; and
  the collection, analysis, and dissemination of explosive hazards information. These tasks mitigate the effects
  of explosive hazards and can be performed by engineers at all echelons or by specialized units (explosive-
  hazards teams, area clearance platoons). Where the tactical situation permits, area clearance is accomplished
  by a USACE-contracted capability.
  Engineers who are trained by EOD trained personnel and have explosive ordnance clearance
  experience not only play a vital role in the assure mobility line of engineer support, but are also equally vital
  for the enhance protection line of engineer support. EOCA trained personnel advise the on-scene commander
  on recommended personnel and equipment protective measures and isolate blast and fragmentation danger
  areas within the AO. EOCA trained personnel may assist EOD personnel in disposing of explosive hazards.
  Engineer mobility and countermobility tasks typically support the assure mobility line of engineer
  support, but they may also support the enhance protection line of engineer support. Examples include
  constructing a trail for use as a perimeter road to secure a base and providing protective obstacles or entry
  control points for the protection of base camps. See ADP 3-37 for additional information.
  Engineer divers enhance protection through force protection dives by identifying and removing
  underwater hazards. Engineer divers improve underwater security measures by checking for the enemy
  tampering of ships, docks, piers, intakes, and other marine facilities. Engineer divers are trained in explosives
  and can identify and remove explosive hazards through sympathetic detonation. Planners and senior staffs
  should be aware of diver capabilities and integrate them into early-entry operations.
  Firefighting teams are limited assets that provide fire prevention and fire protection services. Some of
  the key protection tasks provided to commanders are fire prevention inspections and investigations, fire
  suppression, search and rescue, and hazardous material response. Additionally, these teams provide medical
  response and assistance to victims and offer technical oversight of nonfirefighting personnel when supporting
  firefighting operations.
  Other specialized engineer support teams can be embedded at the tactical level to conduct baseline
  surveys and environmental assessments that enhance protection. These teams identify potential hazards
  before force projection or base and base camp establishment. See ATP 3-34.5 for additional information on
  environmental considerations.
  ENABLE FORCE PROJECTION AND LOGISTICS
  Tasks in the enable force projection and logistics line of engineer support free combat engineers to
  support maneuver forces, establish and maintain the infrastructure necessary to support follow-on forces, and
  sustain military operations to enable force projection and logistics to continue after hostile action and to
  provide recommendations for the site selection of facilities, joint fires, and protection. Engineers combine
  capabilities from the three engineer disciplines to enable force projection and logistics. Primarily through the
  general engineering discipline, these capabilities are applied to enhance strategic through tactical movements.
  Tasks in this line of engineer support sustain military operations in-theater.
