cancelled and the money reclaimed. The supply department allows you to review their material outstanding file to compare it with your known valid requirements. You should advise supply personnel of those items required, those received, and those to be cancelled. After that, supply personnel will reconcile their records and take steps as necessary to cancel, complete, or follow-up on your requisitions. Your role as a CPO is critical, for you know the requirements of the work center and can best determine requisition validity. Close cooperation with supply department personnel is necessary to ensure the accuracy of the MOV procedure. Your leading Storekeeper is best qualified to advise you of time schedules and local procedures. PRIORITIES You should already know how to identify materials, fill out requisition forms, and submit them to the supply department. The department head is responsible for the assignment of priority designators  to  these  requisitions.  Priority designators  are  assigned  according  to  the Uniform Material Movement and Issue Priority System (UMMIPS), which carefully defines the determining factors.    The  system  places  the responsibility directly on the commanding officer of the requesting activity for the integrity of the priorities  assigned;  however,  the  commanding officer usually delegates this authority to the supply  officer.  This  system  should  make  the assignment of inflated priorities rare and ensure a feasible priority system. Two factors determine which of the 15 available priorities will be assigned to each requisition—the  military  importance  of  the activity and the urgency of the requirement. Each ship  or  activity  is  assigned  a  force/activity designator (F/AD), which indicates its military importance relative to other ships and activities. This assignment is made by higher authority (type commander, fleet commander, and so on). The department head is responsible for assigning the correct urgency of need designator (UND) to each material request. By using the F/AD and the UND, the supply department is able to assign the proper priority designator. Table 4-1 lists the F/ADs (shown in Roman numerals) across the column heads and the alphabetical UNDS in the first column. The Roman numerals represent categories of activities in descending order of military importance, ranging from the combat forces under I to the miscellaneous activities under V. The letters in the first column of table 4-1 represent different degrees of urgency in descending order of need, from an unable to perform status (A) to routine stock replenishment (C). The urgency category is selected by the requesting activity. It indicates relative urgency of need for a require- ment by a force or an activity. Categories of each alphabetical designator are defined in the following paragraphs. Only general categories are covered. A complete listing maybe found in Uniform Material Movement and Issue Priority  System  (UMMIPS),  O P N A V I N ST 4614.1F. In each case, the alphabetical designator preceding the category refers to the applicable UND column heading shown in table 4-1. UND CATEGORIES A The activity or unit is unable to perform its mission. The equipment or part is needed immediately. B Repair parts or equipment is required immediately. Ship operation is impaired without it. Stock  replenishment  requirements  of mission-essential material in fleet ballistic missile  (FBM)  submarine  tenders  are below the safety level and are expected to reach a zero balance before receipt of the material. COSAL-allowed   reactor   components, equipment, tools, and other materials are required to support reactor plant systems. C Stock replenishment and normal supply requirements are routine. Material is re- quired to meet scheduled deployment. NOTE: Additional urgency of need designators (UND) may be found in  Afloat Supply Pro- cedures, NAVSUP P-485. RECEIVING AND INSPECTING Before  accepting  material  purchased  from commercial sources, naval activities inspect the material  to  ensure  that  it  conforms  to  the specifications included in the purchase documents. The receiving supply officer inspects the material for quality and quantity before payment is made. 4-13
