detailer. Commanders or commanding officers screen all candidates. MCPOs seeking a CM/C assignment should submit their requests on NAVPERS 1306/7 with their commanding officer’s endorsement and show their desires on a current duty preference form. After one tour as CM/C, the member may receive an assignment within his or her rating. Consideration for a  follow-on  CM/C  assignment  depends  on  the individual’s desires and performance. Upon showing satisfactory performance in a CM/C tour, an MCPO may request and receive NEC 9580 using NAVPERS 1221/1. ASSIGNMENT AS PRIMARY DUTY CM/C Assignments may be without prior approval of the commander/commanding officer except for flag staffs. Flag officers have final approval over candidates nominated to fill billets in their commands. BUPERS selects, details, and orders MCPOs to NEC 9580 billets. In the submarine force, CM/C responsibilities are held by the chief of the boat (NEC 9579). Medical and construction  rating  personnel  will  only  receive assignments to CM/C billets in activities with a primary mission of medical support and construction. SELECTION AS COLLATERAL DUTY CM/C For units with fewer than 250 personnel, a collateral duty CM/C may come from within the command’s resources. Collateral duty CM/Cs can only be U.S. Navy personnel, regardless of rating, based on proven superior leadership qualities and broad management skills. NEC 9580 will not be given to collateral duty CM/Cs. — When a commander/commanding officer does not have an MCPO allowance, a command senior chief petty officer or a command chief petty officer may have that collateral duty. AUTHORITY AND RESPONSIBILITY Since they deal on a daily basis with existing and potential problem areas, FM/Cs and CM/Cs can make effective  and  meaningful  recommendations  for rectifying or preventing undesirable situations. They have an open door policy with their superiors to communicate for the enlisted members of the command. Each of the individuals addressed in this chapter is in an influential and demanding position with a responsibility to maintain effectiveness both up and down the chain of command. These billets do not have the intent to create a new chain of command but to reinforce the existing chain of communications. The following are some of the functions for which FM/Cs and CM/Cs are responsible: Maintaining and promoting effectiveness and efficiency of the chain of command Helping the commander/commanding officer in all  matters  about  the  welfare,  health,  job satisfaction, morale, use, and training of enlisted personnel to promote traditional standards of good order and discipline Advising the commander/commanding officer on formulation and implementation of changes in policy about enlisted personnel Attending  meetings  as  directed  by  the commander/commanding  officer  to  keep apprised of current issues and provide a representative enlisted input Participating in ceremonies honoring command members including all reenlistment ceremonies When  appropriate,  representing  or accompanying  the  commander/commanding officer to official functions, inspections, and conferences Participating in receptions and hosting official visitors to the command Upon invitation, and as approved by the commander/commanding officer, representing the command and the Navy at community and civic functions Participating in, coordinating, or checking the following: Command orientation and indoctrination division Chief  Petty  Officer  or Petty  Officer Indoctrination  Courses Enlisted warfare qualifications Professional Development Board and/or Striker Selection Board Command retention team Awards board considering enlisted personnel Sailor of the month/quarter/year selection boards Human resources management program 2-4
