Painting Table  12-2.—Item  Identification  Designations  for  Cluster Munitions Painting (table 12-1) is the application of the final body coating to ammunition, ammunition components, or  ammunition  containers  by  authorized  activities. Usually,  paint  color  identifies  the  use  or  explosive hazards of the ammunition; however, sometimes it has no meaning. Marking Marking is the application of colored spots, bands, or  symbols  on  ammunition,  ammunition  components,  or ammunition containers. Markings, by their color or shape, identify ammunition fillers or the presence of specific  ammunition  components. Chemical  filler  ammunition,  ammunition components, and ammunition containers are identified by bands that are color coded (table 12-1). Chemical fillers are identified by marking symbols placed on a line parallel to the colored bands. Lettering Lettering  is  the  use  of  letters,  words,  abbreviations, or numerals on ammunition, ammunition components, or  ammunition  containers. Lettering  is  put  on ammunition by die stamping, stenciling, decals, etching, or rubber stamping. Lettering identities the type, mark and modification, ammunition lot number, and loading information of the ammunition item. Lettering applied in  black  or  white  has  no  color-code  significance. Mark and Modification Designation The Mk number is an Arabic numeral and represents a basic design. It is followed by a modification (Mod) number to represent a less than major change in design. For  example,  the  mark/modification  number  assigned  to a general-purpose bomb without a change to the basic design is Mk 82 Mod 0. If a minor change to the basic design is incorporated, it is designated as Mk 82 Mod 1, If further changes are incorporated, the modification designations  are  assigned  in  sequence,  Mod  2,  Mod  3, Mod 4, and so forth. Some explosive devices and ordnance or armament (such as cluster weapons and bomblets used in cluster weapons)  are  designated  by  groups  of  letters  and numbers.  An  example  of  this  type  designation  is BLU-99-A-T-lB   or   BLU-7A/B   (table   12-2).   Other letter-type designators, such as BRU, SUU, FAE, etc., are discussed in other chapters of this TRAMAN. U.S. Army ammunition retains the Army identifier that uses a letter, numeral, and letter and numeral system. For example, the model is designated M23. The  first  modification  of  this  model  is  designated M23A1,  and  subsequent  modifications  are  designated by  M23A2,  M23A3,  etc.  If  an  item  was  jointly developed by the Navy and Army, the model identifying designation  is  preceded  by  the  letters  AN  (Army/Navy). For  example,  a  model  is  designated  AN-M173.  The  first modification  of  this  model  is  designated  AN-M173A1. Later modifications are designated as AN-M173A2, AN-M173A3, etc. Department of Defense Identification Code (DODIC) and Navy Ammunition Logistic Code (NALC) The  Department  of  Defense  Information  Code (DODIC)  is  a  four-digit  code  assigned  by  the  Defense Logistics  Services  Center  (DLSC).  It  identifies ammunition  and  explosive  items  (nonnuclear)  within the supply system applicable to all the armed forces. The  Navy  Ammunition  Logistic  Code  (NALC)  is  a four-digit code assigned by Ships Parts Control Center (SPCC).  It  identifies  Navy-unique  items  of  ordnance. The DODIC and NALC are interchangeable terms and are included as part of the letter identification contained  on  ammunition  and  ammunition  components. These codes are used specifically for logistic control and ammunition  administration. If an ammunition item or ammunition component has been modified, a DODIC/NALC code is assigned to the  modified  item.  For  example,  Mk  105  Mod  0  is assigned code A811 and Mk 105 Mod 1 is assigned code A894. A complete listing of DODICs and NALCs is 12-3
