  5-275. EOD commanders must provide support during large-scale offensive operations by detecting,
  identifying, evaluating, rendering safe, and conducting disposal or disposition of explosive ordnance,
  including CBRN weapons of mass destruction. Planners should consider requirements to mitigate explosive
  ordnance encountered during offensive operations. EOD facilitates technical collection of captured enemy
  materiel related to ordnance or weapons systems. Commanders and planners must incorporate EOD
  requirements within their Class V forecasts. Explosive ordnance filled with insensitive high explosives
  requires significantly more Class V for safe disposal.
  SUSTAINMENT DURING OFFENSIVE OPERATIONS
  5-276. The objective of sustainment during the offense is to support operations and enable maneuver forces
  to conduct the four offensive operations: movement to contact, attack, exploitation, and pursuit. Sustainment
  units supporting offensive operations are focused on sustaining and maintaining the combat power necessary
  to defeat, destroy, or dislocate enemy forces. Successful sustainment commanders and planners will act,
  rather than react, during offensive operations. To support offensive operations, sustainment forces at all
  echelons consider echeloning support assets to expedite replenishment of critical support.
  ECHELONS ABOVE BRIGADE SUSTAINMENT
  5-277. During the offense, LOCs lengthen and requirements for many classes of supply and replacement of
  personnel increase. Certain aspects of the distribution network like rail, pipelines, or inland waterways may
  not be feasible during the offense. The fast pace of the offense generally requires ground or air resupply.
  Offensive operations inherently create a need for emergency resupply, but it is vital that sustainers ensure the
  economy and efficiency of the distribution network. Motor transport is the primary mode of transportation
  during the offense. Its flexibility in allowing multiple stops and rerouting assets enables dynamic battlefield
  support. Use of trailer transfer points can speed up throughput velocity of critical supplies to an offensive
  operation.
  5-278. During the offense, Class V supply is critical for maintaining momentum. Depending on the operation,
  consumption rates may double or triple normal consumption. In addition to accounting for volume,
  sustainment planners also forecast the various
  types of ammunition used by the corps and Echelons Above Brigade Sustainment
  division in the offense. For example, fighting a • Lengthening lines of communications.

  personnel replacements.
  Sustainment planners proactively prepare to
  support maneuver units in the offense with
  configured loads of ammunition, along with fuel and repair parts. Considerations for storage points include
  proximity to main and alternate supply routes, supported units, terrain, and security. Additionally,
  ammunition holding area personnel displace forward as the offense progresses to ensure responsive support.
  5-279. In the offense, combat intensity and the depth of the AO increase. Aerial delivery may reduce the
  impact of these factors, allowing the combat commander to take the initiative while reducing the likelihood
  of overextending their supply lines. During periods of air superiority and while operating in areas with limited
  enemy air defense capability, the use of aerial delivery reduces the ground threat to transportation and
  distribution operations and can be used to extend LOCs. In addition, if forces become isolated, aerial delivery
  can be used as the primary means of resupply. It is also an effective method of resupplying combat outposts
  where it is difficult for ground transportation and distribution lines to reach.
  5-280. Medical planners should closely coordinate with other sustainment planners when preparing for an
  offensive operation. Medical planners also work closely with staffs within the other warfighting functions to
  determine the scope of the operation, develop estimates for the quantity and types of support required, and
  develop a priority of support based on the anticipated need. Medical evacuation is an integral planning factor
  when preparing for an offensive operation. Two basic problems confront the supporting evacuation units in
