  STRATEGIC AND OPERATIONAL REACH
  1-152. Strategic and operational reach enable Army forces to deploy rapidly, fight on arrival, and conduct
  extended campaigns as part of a joint and multinational force. Doing so requires proficiency at force
  projection, protection, and sustainment. Soldiers require an expeditionary mindset to prepare them for short
  notice deployments into uncertain, often austere, and lethal environments.
  1-153. Strategic reach provides the capability to operate against threats operating anywhere in the world.
  The distance across which the United States can project decisive military power is its strategic reach
  (FM 3-0).
  1-154. Operational reach is the distance and duration across which a force can successfully employ military
  capabilities (JP 3-0). Extending operational reach is a major concern for commanders throughout an
  operation. The limit of a unit’s operational reach is its culminating point. Signal support using beyond line
  of sight satellite communications capabilities extends operational reach by increasing the geographic area a
  commander can effectively control.
  OPERATIONAL MOVEMENT AND MANEUVER
  1-155. Operational movement and maneuver combines global force projection with maneuver against an
  operationally significant objective. Successful operational movement and maneuver allows a unit to—
  * Secure and defend a lodgment.
  * Develop support infrastructure and base camps.
  * Receive, stage, and build up forces.
  1-156. Signal support to operational movement and maneuver combines operational science and art to
  ensure the right capabilities are available to support Army commanders, staffs, and units at the right time and
  place. The science of signal support is the technical aspects of communications and the ability to properly
  employ the Army’s wide variety of communications capabilities. The G-6 (S-6) must understand the
  operation plan and articulate the capabilities and limitations of the unit’s communications assets. The scheme
  of signal support effectively distributes capabilities across the organization and employs the network in a
  manner that ensures the commander’s ability to exercise command and control at any time and place on the
  battlefield.
  EXPEDITIONARY CAPABILITY
  1-157. The Army requires expeditionary forces with the endurance to prevail in protracted conflict against
  determined enemies. Expeditionary capability requires deploying the right mix of Army forces to the right
  place at the right time to achieve the desired mission objectives.
  1-158. Expeditionary signal systems and formations enable commanders’ exercise of command and control
  in a constrained environment, whether they are restricted to single-channel radios or are operating with full
  DODIN-A capabilities. The tactical portion of the DODIN-A can scale up or down to meet changing
  operational needs. The signal staff determines the smallest, least complex system available, and the minimum
  staffing necessary to meet the expeditionary mission requirement. Signal staffs determine whether to deploy
  servers forward, utilize reachback to the home station, or rely on strategic enterprise services to support an
  expeditionary mission.
  FORCE PROJECTION
  1-159. Force projection is the military component of power projection. Seizing the initiative generally
  requires force projection. Force projection is a race between friendly and enemy forces. The side that most
  rapidly builds combat power can seize the initiative. During force projection, the ability to scale
  communications packages up or down to meet mission requirements gives commanders flexibility when
  tailoring force projection packages.
