Burn   assemblies   and   components   on   a priority   basis,   if   possible.   Proper   concentration of  equipment  to  be  burned  will  produce  a  hotter, more   destructive   fire. Fires   should   be   lit   after mechanical  destruction  has  been  accomplished. b.   Gunfire. Fire   on   equipment   with   the heaviest   weapons   available   aiming   at   the   major assemblies   and   controls.   Continue   fire   until   the equipment  is  completely  destroyed. c. Mechanical    Destruction. Using   an   axe, pick,   mattock,   sledge   or   any   other   heavy   imple- ments,  damage  or  destroy  all  vital  elements  such  as controls,   and   any   other   major   assemblies   and components. d.  For   further   information,   refer   to   TM   750- 244-3   (Procedures   for   Destruction   of   Equip- ment  to  Prevent  Enemy  Use  for  U.S.  Army. 1-7.   Administrative   Storage If  the  generator  sets  must  be  placed  in  adminis- trative  storage,  proceed  as  follows: a.   (A)   Army. (1)  Store  equipment  so  as  to  provide  max- imum  protection  from  the  elements  and  to  provide access  for  inspection,  maintenance,  and  exercising. Anticipate removal   or   deployment   problems and   take   suitable   precautions. For    example, strategically   locate   recovery   vehicles,   snowplows, slave-units,  and  similar  items,  likely  to  be  needed on  short  notice. (2)   Take   into   account   environmental   con- ditions,  such  as  extreme  heat  or  cold;  high  humi- dity;   blowing   sand,   dust,   or   loose   debris;   soft ground;   mud;   heavy   snows;   earthquakes;   or   com- binations  thereof  and  take  adequate  precautions. (3)   Establish   a   fire   plan   and   provide   for adequate    fire    fighting    equipment    and    personnel. (4)   For   further   information,   refer   to   TM 740-90-1  (Administrative  Storage). b.   (AF)   Air   Force.   Refer   to   TO   35-1-4   (Pro- cessing   and   Inspection   of   Aerospace   Ground Equipment). c.  (MC)  Marine  Corps.  Refer  to  MCO-P4450-7. 1-8.  Preparation  For  Shipment  and  Storage a.   (A)   Army.   Shipment   and   storage   for   U.S. Army   will   be   in   accordance   with   the   following: (1)  Select  the  best  available  site  for  admin- istrative   storage.   Separate   stored   equipment   from equipment   in   use.   Conspicuously   mark   the   area “Administrative   Storage.” (2)   Covered   space   is   preferred.   When   suf- ficient   covered   space   for   all   items   to   be   stored is  not  available,  priority  should  be  given  to  items which   are   most   susceptible   to   deterioration   from the  elements. (3)   Open   site   should   be   improved   hard- stand,   if   available. Unimproved   sites   should   be firm,   well   drained,   and   kept   free   of   excessive vegetation. (4)   Truck,   vans,   Conex   containers,   and other  containers  may  be  used  if  they  provide  the best  available  protection. (5)   Prior   to   storage,   perform   the   next scheduled   major   preventive   maintenance   service. (6)   For   further   information,   refer   t TB    740-97-2    (Preservation    of    USATSARCOM Mechanical  Equipment  for  Shipment  and  Storage). b.  (F)  Air  Force.   Reference  TO  35-1-4  for  end item   generator   set   and   TO   38-1-5   for   installed engine. c.  (N,  MC)  Navy  and  Marine  Corps.   Reference individual service directives for requirements. d.  Placement   of   equipment   in   administrative storage  should  be  for  short  periods  of  time  when  a storage  of  maintenance  effort  exists.  Items  should be  in  mission  readiness  within  24  hours  or  within the   time   factors   are   determined   by   the   directing authority.   During   the   storage   period   appropriate maintenance  records  will  be  kept. e.  Before   placing   equipment   in   administrative storage,   current   maintenance   services   and   equip- ment  serviceable  criteria  (ESC)  evaluations  should be   corrected   and   all   modification   work   orders (MWO’s) should be applied. f.  Storage    site    selection.    Inside    storage    is preferred   for   items   selected   for   administrative storage.   If   inside   storage   is   not   available,   trucks, vans,   conex   containers   and   other   containers   may be used. 1-2 Change 8
