corps. Therefore, if the first three characters are TM 9-, the manual is a
technical manual for an item of equipment for which ordnance has
responsibility.
(3) Supply Group and Class in Group. The first three characters in the
manual identification number are followed by a dash (-) and a four-digit
identifier.
This
four-digit
identifier
contains
two
different
classifications of identification.
(a) Supply Group. The first two numbers of the four digits classify
items of supply under the federal program. For example, in TM 9-2350, the
23 stands for ground effect vehicles, motor vehicles, trailers and cycles.
(b) Class in Group.
The second two numbers identify the classes
within the group. In the example used above, TM 9-2350, the 50 represents
track vehicles.
If the number were 20, it would represent a wheeled
vehicle.
(4) Manuals on Equipment Covered by the Series.
Following the four-
digit identifier of the supply group and class is a dash followed by a
three-digit identifying number. An example would be TM 9-2350-252. In this
particular case, the manual is a technical manual (TM) for ordnance
equipment (9-) covering a ground effect, track laying vehicle (2350-). The
three digits following the federal supply code (2350-) is the Army assigned
sequence number (in this case 252).
This number stands for the number of
vehicles in the federal supply code of 2350. In other words, two hundred
and fifty-one vehicles preceeded the introduction of the Bradley into the
Army's inventory.
(5) Maintenance Level. The next series of numbers represents the level
of maintenance responsible for performing the procedures in the manual. The
first digit represents the lowest level of maintenance responsible for
performing the procedures listed in the manual.
The second digit, unless it is a zero, represents the highest level of
maintenance responsible for performing the procedures listed in the manual.
For example, consider this number:
TM 9-2350-252-34.
As was previously
discussed, TM represents a technical manual that is under ordnance
responsibility (9-), covering a ground effect,
