27. Lot number.-When ammunition is manufactured, an ammu-
nition lot number which becomes an essential part of the marking
is assigned in accordance with pertinent specifications. This lot
number is marked on all packing containers and on the identification
card inclosed in each packing box. It is required for all purposes
of record, including grading, use, and reports on condition, function-
ing, and accidents in which the ammunition might be involved. No
lot other than that of current grade appropriate for the weapon
will be fired. (See par. 28.) Since it is impracticable to mark the
ammunition lot number on each individual cartridge, every effort
should be made to maintain the ammunition lot number of the car-
tridges after they are removed from their original packing. Car-
tridges which have been removed from original packing and for which
the ammunition lot number has been lost are placed in grade 3
(unserviceable ammunition which will not be fired). Therefore,
when cartridges are removed from their original packings they should
be marked so that the ammunition lot number may be preserved.
28. Grade.-Ordnance Field Service Bulletin 3-5 lists numerically
each lot of ammunition with its correct grade as established by the
Chief of Ordnance. Only lots of proper grade will be fired.
29. Marking.-a. Color bands painted on the sides and ends of
the packing boxes may be used to identify the various types of
