advance numerically in accordance with the provisions contained herein for assigning lot interfix numbers (see 4.4 and all paragraphs thereto).

a.   The manufacturer's identification symbol shall be that of the activity

performing the regrouping.

b.   The year and month codes shall correspond to the year and month in which the regrouping was initiated.

c.   Assignment, changes, etc. of the lot interfix numbers and lot sequence

numbers for the "G" lots, shall be accomplished in the same manner as normal production lots as outlined in 4.4 and 4.5 and all subparagraphs thereto.

The following exemplifies the numbering of regrouped lots by a given depot for any item on which regrouping operations are performed.

Example:

QRS75A001G001, QRS75A001G002, etc. QRS75C002G001, QRS75C002G002, etc. QRS75E003G001, QRS75E003G002, etc. QRS75G004G001, QRS75G004G002, etc.

4.7.9.3 Regrouped lots -  Navy lot numbering exceptions.  In some cases, the

Navy's practice is to assign the manufacturer's identification symbol corresponding to

the activity authorizing the regrouping (see 6.7.f).  In other cases when the manufacturing activity is known, an alternate Navy practice is to keep the original manufacturer identification symbol when assigning the new regrouping lot number (see 6.7.f).

4.7.9.4 Regrouped lots -  lot number revisions.  If any additional actions need to be performed on the regrouped lot after the establishment of the lot, such as rework or repair, then suffixes shall be added or changed per this standard.  If applicable, a lot theater indicator can also be added to a regrouped lot number.

4.8 Ammunition lot number -  ammunition lot theater indicators.

4.8.1 Ammunition lot theater indicator description.  The ammunition lot theater indicators identify items that were exposed to combat conditions and environments and provide a means of tracking which lots were sent to which theaters.  The lot theater indicators are normally applied by the using military service prior to returning from theater.  Previous ammunition lot theater indicators used were Y, W, and T and the practice associated with applying an ammunition lot theater indicator varied greatly by service (see 4.8.5 and 6.17).

4.8.2 Ammunition lot theater indicator usage.  To establish a consistent practice across the services, theater indicators shall be placed after the lot suffix at the fifteenth (15th) or sixteenth (16th) position of an ammunition lot number or a propellant lot number.
