text: Introduction
  This revision of FM 3-34 aligns with the joint phases as described in FM 3-0. Most joint operations share
  certain activities or actions in common. There are six general groups of military activities that typically occur
  in preparation for and during a large-scale joint operation. These six groups are shape, deter, seize the
  initiative, dominate, stabilize, and enable civil authorities. These six general groups of activities provide a
  basis for thinking about a joint operation in notional phases. These phases often overlap, and they are not
  necessarily sequential. Introductory figure-1 shows the Army’s strategic roles in a general relationship to
  joint phases.

  The Army Engineer Regiment is a mix of capabilities which spans from the Active and Reserve Component
  to the USACE and Civilian corps capabilities. There are two basic categories of operating force engineers of
  the Regiment—organic and force pool. The capabilities and capacity in the force pool exist to augment
  organic brigade combat team (BCT) engineers and provide echelons above the BCT complementary engineer
  capability and capacity. Force pool engineers units and capabilities available from either the Forces
  Command or from those assigned to the Headquarters, Chief of Engineers.
  The Engineer Regiment provides specialized capabilities across the range of military operations. These
  capabilities include sappers, construction engineers, divers, firefighters, geospatial cells, and military
  working dog teams. However, after 17 years of counterinsurgency operations, the Army has shifted its focus
  to large-scale ground combat to ensure that U.S. forces are trained and ready to meet emerging threats. This
  refocus to large-scale ground combat does not suggest a shift in the simultaneous nature of decisive action.
  The latest revision of the engineer framework (see introductory figure-2, page vi) provides the intellectual
  underpinnings for the Engineer Regiment and refines the Regiment’s purpose and major activities. These are
  referred to as the lines of engineer support. The engineer framework describes how engineers combine the
  skills and organizations of the three interrelated engineer disciplines (combat, general, and geospatial
  engineering) to provide support to commanders that assures mobility, enhances protection, enables force
  projection and expeditionary logistics, builds partner capacity, and develops infrastructure among
  populations and nations.
  The three engineering disciplines are commonly interdependent, interrelated, and foundational to how
  engineer units are organized and lines of engineer support. The geospatial engineering discipline is also
  considered the foundation that supports the combat and general engineering disciplines and lines of engineer
  support. In introductory figure-2, the combat and general engineering tasks commonly overlap because of
  the support they provide to the Army’s missions and end states. The lower section of general engineering is
  also greyed as an acknowledgement of general engineering’s inseparable link to United States Army Corps
  of Engineers (USACE) civil works. The engineer disciplines provide the means of enabling the lines of
