  enemy avenues of approach to best utilize the restricted and severely restricted areas forward in the BCT’s
  area of operations.
  EXAMPLE BCTAREA DEFENSESCENARIO
  This fictional scenario for steps 4,5,and 6 of the EAdevelopment process,used for discussion purposes,is
  an example of how a BCT commander might build EAs within an area defense. In this scenario,an IBCT
  conducts an area defense against a motorized Infantry and armor threat. Army aviation attack and
  reconnaissance units,initially control by division and higher echelon,conducted attacks against enemy forces
  not in direct contact with the ground maneuver forces of the IBCT. As the enemy advanced,aviation attacks
  continued in close proximity or in direct support of IBCT and battalion security forces and main battle area
  forces. Artillery and mortar fire support plans were integrated into forward security area actions and the direct
  fire plans of maneuver companies in the main battle area. Engineer priorities of work were initially to
  countermobility,then to survivability. As the IBCT prepared for the defense,the brigade support battalion
  established the brigade support area (BSA) just forward of the division support area to support the BCT area
  defense.
  The IBCT is task organized with two Infantry battalions,a combined arms battalion,aCavalry squadron,a
  field artillery battalion, a brigade engineer battalion, and a brigade support battalion. Infantry Battalion 2
  (main effort) is task organized with two Infantry rifle companies,a mechanized Infantrycompany team (two
  mechanized Infantry platoons and one tank platoon),and a weapons company. Company C,the third Infantry
  rifle company (mounted) from Infantry Battalion 2, was placed under IBCT control as the reserve for the
  BCT. Infantry Battalion 1 istask organized with its three Infantry rifle companies and weapons company.
  The combined arms battalion is task organized with two armor company teams,each with two tank platoons
  and one mechanized Infantry platoon. The commander weighted the main effort by attaching the mechanized
  Infantry company team from the combined arms battalion to Infantry Battalion 2,as stated above. No change
  in task organization for the IBCT Cavalry squadron,field artillery battalion,and brigade engineer battalion.
  The brigade support battalion is task organized with the logistical elements required to support the combined
  arms battalion. Subordinate unit task organization and scheme of maneuver are as follows:
  (cid:122) Infantry Battalion 2,main effort,conducts an area defense. The battalion defends in-depth with
  two Infantry rifle companies,with one assault platoon each attached,forward,and a mechanized
  Infantry company team (two mechanized Infantry platoons) and weapons company (two assault
  platoons) back. The tank platoon from the mechanized Infantry company team is the battalion
  reserve. (Illustrated within EAdevelopment example,see figure 7-14 on page 7-42.)
  (cid:122) Infantry Battalion 1, supporting effort, conducts an area defense to the north of Infantry
  Battalion2. The battalion defends in-depth with two Infantry rifle companies forward,and one
  Infantry rifle company back. The weapons company (two assault platoons) is the battalion reserve.
  (Not illustrated.)
  (cid:122) The combined arms battalion,two armor company teams,is the counterattack force for the BCT.
  (Not illustrated.)
  (cid:122) Infantry rifle company C from Infantry Battalion 2 is the reserve for the BCT. Company C is
  mounted and has two attached assault platoons from Infantry Battalion 1. (Not illustrated.)
  (cid:122) The Cavalry squadron establishes the security area forward of the BCT main battle area. (Not
  illustrated.)
  (cid:122) The brigade engineer battalion priorities of work, countermobility, survivability, and then
  mobility. Priority of engineer effort initially to Infantry Battalion 2, then to the mobility of the
  BCT counterattack force.
  (cid:122) The field artillery battalion provides priority of fires initially to security area forces, then to
  Infantry Battalion 2,on order to the BCT counterattack force. (Not illustrated.)
  (cid:122) The brigade support battalion establishes the BSA just forward of the division support area.
  Priority of support initially to security area forces,then to Infantry Battalion 2,finally to the BCT
  counterattack force. (Not illustrated.)
  7-145. Step 4. Position subordinate forces and weapons systems. Within the above scenario, the Infantry
  brigade combat team (IBCT) commander’s concept for the area defense required the positioning of
  subordinate forces and weapon systems to accomplish their mission independently and in combination by
  means of fires,the employment of obstacles,and absorbing the strength of the attack within defensive battle
