C-2. GENERAL The    components of   End     Item   and     Basic     Issue Lists   are    divided into   the    following     sections: a. Section II.   Components of   End    Item. This     listing   is   for   informational purposes only,   and    does not give    authority to   requisition replacements. These items     are    part    of  the    end     item,    but   are    removed and    separately packaged for   transportation or  shipment. As   part    of  the    end    item,   these items     must    be   with   the    end    item   whenever it is  issued or   transferred between property accounts. Illustrations are   furnished to  assist you    in  identifying the    items. b. Section Ill.    Basic     Issue     Item(s)     (BII(s)). These are   the    minimum     essential items    required to   place the     Special Diver    Air   Support System (SDASS) in  operation, to   operate it,   and     to   perform emergency repairs. Although packaged separately when shipped, BlIs   must    be    with   the    Special Diver    Air  Support System (SDASS) during     operation and    whenever it  is  transferred between property accounts. The     illustrations will  assist you   with hard-to-identity items.
