  EXECUTIVE OFFICER
  4-193. The XO is the commander’s principal assistant and directs staff tasks, manages and oversees staff
  coordination,and special staff officers. The commander normally delegates executive management authority
  to the XO. The XO provides oversight of sustainment planning (see chapter 9) and operations for the BCT
  commander. As the key staff integrator,the XO frees the commander from routine details of staff operations
  and the management of the headquarters and ensures efficient and prompt staff actions. The XO may be
  second in command. The XO leans heavily on recommendations of the staff in each member’s area of
  expertise,while at the same time balancing competing priorities for the overall situation. This delicate balance
  assists the commander as the XO anticipates the decision-making cycle and commander’s intent,helping the
  commander to make informed decisions,while empowering the staff and guiding them. For example,the S-6
  may recommend an optimal location for the BCT’s main CP based on atmospherics,but the S-2 knows how
  easily the adversary will identify such a location. TheXO might direct them to evaluate the advantages and
  disadvantages to such a location,along with two additional possible locations,determining which best meets
  the commander’s intent,or presenting the accumulated analysis with a recommendation to the commander.

  personnel officer and the equal opportunity advisor and prepares a portion of Annex F (Sustainment) to the
  operation order. When planning an operation,the S-1 provides accurate information regarding replacement
