Investigate matters affecting the discipline and conduct of the crew and makes recommen- dations concerning these matters to the commanding officer. Approve  or  disapprove  liberty  lists  and  leave requests. Inspect  the  ship  and  receive  readiness  reports from the various department heads when the ship is cleared for action; then report to the CO when the ship is ready for action. If  the  captain  is  disabled  during  battle,  the  XO normally becomes the acting commanding officer. For this  reason,  the  location  of  the  XO’s  battle  station (determined by the captain) is some distance from the captain’s. This prevents disablement of both officers at the same time. After a battle, the executive officer makes a detailed report to the commanding officer. If   the   XO   cannot   fulfill   the   duties   of   the commanding  officer,  normally,  the  next  senior  line officer assigned to the ship assumes the duties of the commanding officer. Depending  on  the  size  of  the  ship,  the  executive officer may have one or more assistants. Some of these assistants and their responsibilities are as follows: Personnel officer.  The  personnel  officer  assigns personnel  to  the  various  departments,  berthing arrangements,  and  to  the  task  of  maintaining  enlisted service records. Training officer.  The  training  officer  secures school quotas, schedules orientation courses for newly reporting  personnel,  and  helps  prepare  long-  and short-range training schedules. Educational services officer (ESO).   The educational  services  officer  (ESO)  receipts  for, maintains,  and  distributes  educational  courses  and training aids. Drug and alcohol program advisor (DAPA). The drug and alcohol program advisor (DAPA) advises the CO and XO on all matters concerning the Navy’s Drug and  Alcohol  Abuse  Program.  The  DAPA  provides onboard  education,  prevention,  screening,  command counseling,  aftercare,  probationary  supervision, motivational training, and referral services. Command master chief (CM/C).  While  serving as  one  of  the  XO’s  assistants,  the  CM/C  has  direct access  to  the  CO  and  is  the  voice  of  all  enlisted personnel. In addition to these assistants, the executive officer may  also  have  a  legal  officer,  combat  cargo  officer, safety   officer,   and   others   as   required.   The master-at-arms  force  also  works  directly  under  the executive officer. DEPARTMENT HEAD As  the  representative  of  the  commanding  officer, the department head is responsible for and reports to the CO about all matters that affect the department. That includes  administrative  matters,  the  operational readiness of the department, and the general condition of equipment. DIVISION OFFICER The  division  is  the  basic  unit  of  the  shipboard organization.  The  CO  assigns  division  officers  to command  the  divisions  of  the  ship’s  organization. Division officers are responsible to and, in general, act as assistants to department heads. The  number  of  divisions  in  a  department  varies among  ships,  with  each  division  having  only  a  few assigned personnel to as many as 200 personnel. The division  officer  is  a  major  link  in  your  chain  of command, particularly in a small ship. At the working level, the division officer carries out command policies and personally sees that division tasks are completed in a timely manner. Some of the division officer’s duties include— Making  frequent  inspections  of  division personnel, spaces, equipment, and supplies Maintaining  copies  of  all  division  orders  and bills and displaying them in a conspicuous place Training division personnel and preparing them for battle 6-10 Student Notes:
