text: Engineer Echelon Perspectives
  Army commanders assume a support role to one or more designated agencies. Engineers can expect to
  be involved in planning for the support of relief operations, with geospatial products and analysis of potential
  areas to establish life-support areas. Engineers may be called on to provide manpower support or general
  engineering support from units with unique capabilities, such as water purification, temporary shelter, power
  generation, and firefighting. Engineer commanders and staffs work with the proponent planners to identify
  requirements and plan engineer applications. The USACE and other engineering capabilities of the
  institutional force have prominent roles during DSCA operations:
  * Urban search and rescue.
  * Route opening and route clearance.
  * Temporary and tactical bridging.
  * Environmental control and groundwater sampling.
  * Decontamination site and holding-pond construction.
  * Humanitarian and temporary shelter construction.
  * Controlled demolition (in support of mass firefighting operations in urban areas).
  * Power generation and distribution.
  * Firefighting.
  * Debris removal.
