lubricants. It issues materials and operates various types of  material  handling  equipment. LABOR AND EQUIPMENT BRANCH.— This branch maintains a residual labor and equipment pool. It determines and furnishes requirements for material handling  equipment.  It  also  furnishes  laborers,  high  lift truck  operators,  and  other  ungraded  personnel  not permanently  assigned  to  the  part  of  supply  using  them. This branch also gets and distributes transportation and weight  handling  equipment  when  public  works  does  not provide  them. SHOP STORES BRANCH.— When  established, this  branch  controls  and  operates  shop  stores  according to current directives. It provides personnel for storage, counter  service,  record  keeping,  and  stock  control functions. It works together with the department served in setting the range and depth of needed stock items in shop stores. When other commands set up this store and the stock is part of the store’s account of the supporting command, it is considered a ready supply store. The organization concept of a ready supply store is the same as a shop store. FUEL   BRANCH.—   When   authorized   by NAVSUP supply may set up a Fuel branch when it is required by workload and scope of operations. This branch  receives,  stores,  and  issues  fuels.  At  activities with limited storage capacity, the Fuel branch also may determine  requirements  and  schedule  deliveries  of fuels. FOOD   SERVICE   DIVISION.—   The   supply department may set up this division when authorized by NAVSUP This division is also known as the enlisted dining  facility  (EDF).  The  organization  of  a  Food Service  division  largely  depends  on  the  size,  physical layout, facilities of the station, and number of personnel subsisting in the facility. The Food Service division operates the enlisted dining facility. It also performs administrative  functions,  such  as  maintaining  records and submitting returns. AVIATION   SUPPORT   DIVISION.—   TMS division is also known as the supply support center (SSC).  It  is  responsible  for  providing  supply  support  for assigned  organizational  and  intermediate  maintenance activities  (OMA  and  IMA).  The  Aviation  Support division  (ASD)  is  the  single  point  of  contact  for maintenance  activities  requiring  direct  supply  support. It is where Material Control places requirements for material and equipment needed to support maintenance of  weapons  systems.  Material  Control  places  these requirements  by  submitting  requisitions  to  ASD. Chapter  9  of  this  training  manual  describes  ASD responsibilities  and  functions  in  detail. Afloat The  organization  of  the  supply  department  afloat varies according to the mission, physical characteristics, and complement of the ship. As an AK, you will most likely be assigned to an aircraft carrier (CV or CVN) or an  amphibious  assault  ship  (LPH).  The  supply organization structure for these ships can be found in Afloat  Supply  Procedures,  NAVSUP   P-485,   and Automated  Snap  1  Supply  Procedures,  volume  1, NAVSUP   P-567.   The   NAVSUP   P-567   provides illustrations of typical supply organizations for different types of ships. Figure 1-5 of this chapter provides an example  of  a  supply  department  organization  afloat. As a member of the supply department aboard ship, you will be dealing with personnel in other divisions. To perform your duties effectively, you must be familiar with  the  different  divisions.  During  weekends  and  after normal working hours, only the duty section staffs the supply  department.  The  duty  section  consists  of personnel from other divisions of the supply depart- ment.  With  few  people  in  the  duty  section,  all  its members  have  to  participate  to  accomplish  any  major task. You must know all the members and where they work, because you may have to contact everyone for a muster or meeting. You may become part of different working party evolutions  aboard  ship  or  pierside.  The  underway replenishment  (UNREP)  or  vertical  replenishment (VERTREP)   evolutions   consist   mostly   of   supply personnel  from  different  divisions.  In  separating material, you must know how to differentiate items for ship’s store, stock or direct turnover (DTO). You must be able to segregate stock items for general stores, clothing,   subsistence,   and   aviation   stores.   After segregating the items, it might be your job to tell each division responsible for the material to pick it up. The following paragraphs will help you familiarize yourself with  the  supply  organization  aboard  ship. SUPPLY   OFFICER   AND   ASSISTANT (AFLOAT).— The supply officer (SUPO) is the senior supply corps officer on board the ship and is the head of the supply department. The supply officer is responsible to the commanding officer for the performance and administration  of  all  supply  functions. The assistant supply officer (ASUPO) is also the primary assistant on aircraft carriers. The primary responsibility of the ASUPO is to ensure the proper 1-11
