track laying vehicle (2350-), specifically the M2/M3 Bradley Fighting
The next two digits, 3 and 4, represent the lowest and
highest levels of maintenance responsible for performing the procedures
listed in the TM.
In this case, 3 would represent intermediate direct
support (IDS) and 4 would represent intermediate general support (IGS).
However, if the second digit had been a zero (0), then the maintenance
responsibility would have been determined by the first digit only.
this system, it is easy to distinguish that TM 9-2350-252-10 contains tasks
that are performed by the operator and that TM 9-2350-252-20 contains
procedures that are performed by unit maintenance only.
If the two-digit
number were a 12, the procedures contained in the TM would be performed by
either the operator, at the lowest level, or by the unit mechanic at the
(6) Additional identification Digits.
All identifying digits that are
added to the manual identifying number are defined by the maintenance level
of the manual.
(a) Operator/Crew Level. There is only a single digit that follows
the -10 level indicator at the operator/crew level.
This digit, when
present, represents the volume number of the manual.
Whenever a manual
exceeds one thousand pages, it is divided into three volumes, with each of
the volumes containing some of the chapters of the manual.
(b) Unit Maintenance Level.
The unit maintenance level -20
identifier can be followed by as many as three individual digits, each
separated by a dash.
o The first of these digits designates the portion of the vehicle
covered by the manual. A 1 would indicate that that portion of the manual
would be for the hull, a 2 represents the turret.
o The second digit designates the volume number. At the unit level of
maintenance, volume 1 contains the preventive maintenance checks and
services (PMCS), volume 2 contains the troubleshooting procedures, and
volume 3 contains the maintenance procedures.
