  reconnaissance and site assessment support to the BEB. The CBRN reconnaissance platoon
  receives administrative and sustainment support from the BEB. See FM 3-11 for more information
  on the employment of CBRN reconnaissance platoons.
  The BCT commander directs command and support relationships within the BCT. These dictate
  whether the BEB will logistically support or coordinate support with the BCT for attachments. Unless the
  BCT directs otherwise, the BEB retains a command or support relationship with organic and attached units.
  Organic companies and companies that are operational control (OPCON) to the BEB may be further task-
  organized to maneuver task forces, the reconnaissance squadron, or a subordinate company or troop. Unless
  the BCT directs otherwise, the BEB retains command and support relationships with organic and attached
  units, regardless of their physical location. The companies may be further task-organized to maneuver task
  forces, the reconnaissance squadron, or a subordinate company or troop.
  Two engineer companies provide the BCT the minimum capability to support the offense and defense
  (breach and cross obstacles, assist in the assault of fortified positions, emplace obstacles to protect friendly
  forces, construct or enhance survivability positions, conduct route reconnaissance and information collection,
  identify and clear improvised explosive devices). This maintains the BCT freedom of maneuver and inhibits
  the enemy ability to mass and maneuver. Each company is slightly different, but the primary focus is to
  support the combat engineering discipline with breaching, gap crossings, digging assets, and route-clearance
  capabilities.
  Company A
  Engineer Company A is identical in the armored and infantry BCTs. This engineer company provides
  combat engineer support, and it consists of a company headquarters, two combat engineer platoons, and one
  engineer support platoon. The company provides mobility, countermobility, and survivability (M/CM/S), and
  limited construction support to the BCT. The combat engineer platoons provide the BCT assets for breaching
  and obstacle emplacement. The engineer support platoon consists of a platoon headquarters; a horizontal
  squad that provides specialized engineer equipment to support limited general engineering tasks assigned to
  the company; and a breach squad that provides specialized equipment to support mobility, countermobility,
  and sustainment tasks assigned to the company. In a Stryker BCT, Engineer Company A has a company
  headquarters and two combat engineer platoons; but instead of an engineer support platoon, it has a bridge
  section. The breach squad of the Stryker BCT is limited to mine-clearing line charges and proofing equipment
  in the company. Generically, each company organization is depicted in figure 1-2, page 1-6.
