  PhaseII –– Assault
  1-108. Assault phase, in airborne and air assault operations, a phase beginning with delivery by air of the

  activitiesinclude:
  (cid:122) Initial assault designed to surprise and overwhelmthe enemy with decisive force and to protect
  assaultforce.
  (cid:122) Overcoming natural and man-made obstacles intended to restrict or halt movement that allows

  PhaseIII – Stabilizationofthe Lodgment
  1-109. Stabilization of the lodgment involves securing the lodgment to protect the force and ensure the
  continuouslandingofpersonnelandmateriel.
  (cid:122) Organizing the lodgment to support the increasing flow of forces and logistic resource
  requirements.
  (cid:122) Expanding the lodgment as required, support the joint force in preparing for and executing
  follow-onoperations.
  (cid:122) Transitionto introducing follow-on forces intended to conduct follow-onoperations, in extreme
  circumstances, follow-on forces may be required to assist assault forces in the seizure of initial
  objectives,ormaybeusedtohelpsecureanddefendthelodgment.
  PhaseIV – Introductionof Follow-OnForces
  1-110. The introduction of follow-on forces is required when subsequent operations are planned for
  conduct in or from the lodgment. It provides the joint force commander with increased flexibility to
  conductoperationsasrequired.
  Phase V – Terminationor Transition

  SECTION II – VERTICAL ENVELOPMENT
  1-112. Operational experience has demonstrated that the rapid projection of combat power is the key to
  successful ground and littoral maneuver. Experience and analysis have shown that the most effective
  method of doing so is through a combination of vertical and surface means. These complementary means
  provide flexibility in negating threats unique to operational access. This section addresses vertical
  maneuverwithinforcibleentryoperations,theairborneorairassaultforce,andcommandresponsibilities.
  TACTICAL APPLICATIONS
  1-113. Forcible entry, composed of an entry force, together with other forces that are trained, organized,
  and equipped for entry operations, project power. Forcible entry can be executed through vertical
  envelopment, directly against the enemy in a sudden attack in force to achieve decisive results or to
