  * FSCMs—accounting for danger close and other technical constraints—allow maneuver forces to
  get as close as possible to the objective before lifting fires.
  * Signals for lifting and shifting fires on the objective.
  * Do not dilute fire support capabilities to the extent they are unable to concentrate in support of the
  main effort.
  * Plan for echelonment of fires.
  * Maximize use of organic fires.
  SUSTAINMENT
  5-28. Units prioritize their sustainment operations to support their attacking forces. They prioritize
  sustainment support by designating who has priority for resupply combined with task-organizing capabilities
  (for example, shifting fuel tankers and operators from one unit to another). Prioritization weights the main
  effort by ensuring the right forces have the required supplies and equipment to accomplish the most important
  tasks.
  5-29. Lines of communication typically increase during attacks. Therefore, units consider forward
  positioning sustainment assets to increase their operational reach and flexibility. Units also consider the
  availability and feasibility of using aerial assets to augment ground-based sustainment operations. This
  includes the ability to execute aerial resupply and aerial medical evacuation. Units must not assume the
  friendly forces possess air supremacy or air superiority which may preclude the use of aerial assets to execute
  sustainment operations.
  5-30. Units must balance positioning supporting sustainment assets forward to support the attacking force
  with maintaining force protection. Forward positioning sustainment assets can create a risk. If the enemy is
  able to target and destroy these assets, then they may force the culmination of friendly operations prior to
  their success. Commanders need to balance account for this risk when considering the placement of
  sustainment assets during an attack. From these forward locations, units can sustain attacking forces and
  when applicable, shift priority of support to the units conducting the main effort. As attacking forces advance,
  their supporting sustainment units and capabilities displace forward as required to shorten supply lines, using
  displacement techniques designed to ensure uninterrupted support to maneuver units.
  PROTECTION
  5-31. Prioritization of protection tasks is vital to supporting an attack, however the prioritization will vary
  by echelon based on the resources and capabilities available. The mission variables guide the priorities or
  protection tasks and resources. Protections tasks that support the attack include but are not limited to: OPSEC,
  detention operations, CBRN operations, survivability operations, area security, and air and missile defense.
  PREPARING FOR AN ATTACK
  5-32. Even in fluid situations, attacks are best organized and coordinated in assembly areas. Units may opt
  not to use assembly areas if they determine that rapid action is essential to retain tactical advantages. Detailed
  advance planning—combined with digital communications, SOPs, and battle drills—may reduce negative
  impacts of such a decision.
  5-33. Attacking units move into their assembly areas during the preparation phase unless they are already
  located in their assembly area. They move with as much secrecy as possible, normally at night and along
  routes that prevent or degrade an enemy force’s capabilities to observe or detect their movement. They avoid
  congesting their assembly areas and occupy those areas for the minimum possible time. Units are responsible
  for their own protection activities, such as local ground security, while in their assembly areas.
  5-34. Attacking units continue priorities of work to the extent the situation and mission allow before moving
  to attack positions. Preparations include but are not necessarily limited to—
  * Protecting the force.
  * Task-organizing.
  * Performing reconnaissance.
