MIL-STD-1168C

If no suffix is currently assigned or a single character suffix is present, then the theater indicator shall be in the fifteenth (15th) position.  When no suffix is present, then a single hyphen shall be used as a placeholder for a possible future suffix.  (Note: To prevent confusion and ensure readability, it was determined that a double hyphen placeholder for the two character suffix shall not be used.)  If a two character suffix is already present or

a single character suffix transitions to a two character suffix, then the theater indicator shall be in the sixteenth (16th) position.  The following examples illustrate how the theater indicator shall be assigned.  While most of the examples use ammunition lot numbers, propellant lot numbers shall follow the same guidance.

Examples:

For the purposes of this example, the character "Z" is hypothetically chosen as the

next lot theater indicator.

a.   An ammunition lot number with no suffix:

EFG02B005-043              becomes          EFG02B005-043-Z

b.   An ammunition lot number with a single suffix:

EFG02B005-043D            becomes          EFG02B005-043DZ

c.   An ammunition lot number with a double suffix:

EFG02B005-043BA         becomes          EFG02B005-043BAZ

d.   An ammunition lot number with a suffix transitioning from single to double suffix:

EFG02B005-043VZ         becomes          EFG02B005-043AAZ

Note: In this case "V" was the last suffix letter since "Z" would not be

allowed to be both a suffix and a theater indicator.

e.   A propellant lot number with no suffix:

IND90B-G70888              becomes           IND90B-G70888-Z

If the theater indicator is to be placed on older format lot numbers, then the theater indicator shall be added at the end of the lot number and preceded by a hyphen if no suffix is present or after the suffix if one is present.

Examples:

For the purposes of this example, the character "Z" is hypothetically chosen as the next lot theater indicator.

a.   An older format ammunition lot number with no suffix: AB-223-5              becomes          AB-223-5-Z

b.   An older format ammunition lot number with a single suffix: AB-223-5A           becomes          AB-223-5AZ
