  AGILITY
  2-15. In operational environments characterized by friction, uncertainty, violence, and change, the ability to
  act faster than the enemy is critical for success. Agility is the ability to move forces and adjust their
  dispositions and activities more rapidly than the enemy(FM 3-0). While initiative implies a bias for action,
  agility enables the action to occur before enemy forces can effectively react. Moving forces on the battlefield
  and conducting transitions requires commanders to assume risk. JAG Corps personnel help assess risk and
  provide legal options to protect the mission and the force.
  CONVERGENCE
  2-16. Peer threats employing adaptable, durable capabilities and formations make it unlikely that they can
  be defeated in a single, decisive effort. Success requires Army forces to sustain attacks against multiple
  decisive points across multiple domains and dimensions over time to create windows of opportunity.
  Convergenceis an outcome created by the concerted employment of capabilities from multiple domains and
  echelons against combinations of decisive points in any domain to create effects against a system, formation,
  decision maker, or in a specific geographic area (FM3-0). Convergence is a top-down driven outcome from
  the senior Army tactical echelon, informed by an understanding of the larger land tactical situation and
  influenced by access to multination, joint, and Army capabilities.
  2-17. Achieving convergence requires an understanding of the enemy and friendly situations and other
  factors in the operational environment. JAG Corps personnel identify critical legal factors in the information
  and human dimensions that contribute to the set of decisive points necessary for achieving the overall
  objectives of convergence.
  ENDURANCE
  2-18. Endurance is the ability to persevere over time throughout the depth of an operational environment
  (FM3-0). Endurance enhances the ability to project combat power and extends operational reach. Endurance
  is about resilience and preserving combat power while continuing operations for as long as is necessary to
  achieve the desired outcome. During competition, Army forces improve endurance by setting the theater
  across all warfighting functions and improving interoperability with allies and other unified action partners.
  2-19. Violations of the law of armed conflict and rules of engagement have the potential to erode
  international support, erode national will to fight, and violate the trust of host nation populations. Legal
  support to operations helps maintain the trust, will, and support required to sustain operations long enough
  to fulfill mission requirements and sustain lasting policy objectives.
  DEPTH
  2-20. Depthis the extension of operations in time, space, or purpose to achieve definitive results (ADP3-0).
  While the focus of endurance is on friendly combat power, the focus of depth is on enemy locations and
  dispositions across all domains. Commanders achieve depth by understanding the strengths and
  vulnerabilities of the enemyforces’ echeloned capabilities, then attacking them throughout their dispositions
  in simultaneous and sequential fashion. Although simultaneous attacks through all domains in depth are not
  possible in every situation, leaders seek to expand their advantages and limit enemy opportunities for
  sanctuary and regeneration. Leaders describe the depth they can achieve in terms of operational reach.
  2-21. Depth does not just apply to geography and physical factors. Legal support contributes to achieving
  depth in the information and human dimensions. Good order and discipline and concerted efforts to uphold
  the law of war and rules of engagement strengthen trust within an alliance and deny threat opportunities to
  disrupt the cohesion of alliances, even when attempting to accomplish difficult missions in complex
  environments.
