TM 5-3895-368-14&P Section II.  MAINTENANCE 2-1. THE MAINTENANCE STRUCTURE: There   are   four   levels   of   maintenance:      Unit,   Direct Support,  General Support, and Depot.  These four levels of  maintenance  form  the  baseline  for  determining  task assignments   at   each   level.      However,   the   number   of maintenance  levels  may  be  tailored  to  accommodate  a specific  material  system  or  commodity  grouping  when justified. a. Unit     Maintenance:          Each     combat,     combat support, and combat service support activity is authorized   an   organic   material   maintenance   element (i.e.,    crew/operator    and    maintenance    personnel)    to perform    authorized    unit    maintenance    operations    on equipment  assigned  to  or  used  by  it  to  accomplish  it’s mission. b. Direct    Support    Maintenance:        Divisional    and nondivisional  direct  support  units  are  authorized  in  the Army force structure to provide direct support maintenance  service  to  the  Army  in  the  field.    One-stop service, to the extent practical, is the goal of these units. c. General Support Maintenance:  General support maintenance operations primarily are aimed at the repair of  end  items  of  modules  for  return  to  the  local  area  or theater   stocks   of   the   support   of   the   direct   exchange program.      Normally,   general   support   units   operate   in shops and are considered movable, but not mobile. d. Depot Maintenance: Depot maintenance operations    support    both    the    overall    Army    inventory management program and the combat forces.  They are used    as    an    alternative    or    a    supplement    to    new procurement  as  a  source  of  serviceable  assets  to  meet Army material requirements. 2-2. MAINTENANCE ALLOCATION CHART (MAC): The   Maintenance   Allocation   Chart   (MAC)   will   be   the primary  tool  for  assigning  tasks  within  the  levels  of  the Army maintenance system. 2-3. QUALITY   DEFICIENCY    REPORT    (QDR)    AND EQUIPMENT IMPROVEMENT RECOMMENDATION (EIR): All   Army   material   is   subject   to   QDR   and   EIR.      The purpose   of   submitting   a   QDR   is   to   report   conditions which are the result of below standard quality workmanship.    This  purpose  of  an  EIR   is   to   suggest material improvements in design, operations, or manufacture.  Reporting instructions for QDRs and EIRs are  contained  in  DA  PAM  738-750  and  DA  PAM  738- 751. 2-4. MAINTENANCE EXPENDITURE LIMITS (MEL): The average life expectancy for the Asphalt Melter is 15 years. PRODUCTION YEAR EXPENDITURE LIMITS 50% 45% 40% 35% 30% 20% 1995 2005 2006 2007 2008 2009 2010 2-5. PRESERVATION, PACKING, AND MARKING: The items destine for POMCUS or  long  term  storage  at CONUS  Depots,  the  preservation,  packing  and  marking shall  be  level  A/A  in  accordance  with  MIL-D-771.    For items   destine   for   OCONUS   for   immediate    use,    the preservation,  packing  and  marking  shall  be  level  B/B  in accordance   with    MIL-D-771.        For    items    destine    for CONUS   for   immediate   use,   the   preservation,   packing and   marking   shall   be   commercial   in   accordance   with MIL-D-771. 2-6. DESTRUCTION TO PREVENT ENEMY USE: Refer  to  TM  750-244-6,  Procedures  For  Destruction  of Tank-Automotive    Equipment    to    Prevent    Enemy    Use (U.S. Army Tank-automotive and Armament Command). 2-7.
