I was trying to figure out the TM situation in the thread above but they closed it for comment. I went to a different forum here that said I have insufficient credentials so here we go.
I bought the printed version of these three for my 2004 M1123 but found that the information I was looking for was not in them.
TM 9-2320-280-3
TM 9-2320-280-24P2
TM 9-2320-280-24P1
I'm looking for what the military uses to actually do the maintenance procedures with. Would that be
TM 9-2320-387-24-1
TM 9-2320-387-24-2
.
The "Closed For Comments" in the TM Section is just to cut down on opinions about the Technical Manuals. Once posted here and the upload is "Closed" that confirms that we have a known good book. AND that it is confirmed to be Approved for public release (distribution).
Lifted from Mike:
Well, some others have delved into this subject before, so we probably ought to look at what they have to say. First the current Army numbering scheme can be found at
https://radionerds.com/index.php/TM_Numbering_Specification and a writeup I found elsewhere says "
Early TM’s have numbers like “TM 9-2300”. The first number being the subject or branch of the Army. Number “9” means that it is an Ordnance Branch manual. The second series of numbers referring to the particular manual.
The many later TM’s, concerned with single pieces of equipment, especially Ordnance equipment, were numbered like “TM 9-1005-223-12”. The
first number refers to the branch. The number “9” means that it is an Ordnance branch document. The
second series of numbers refer to the subject type. The
third series refers to the particular piece of equipment or subject.
The four series on numbers refer to the level of maintenance which the manual is concerned with. With “10-12” being operator and organizational maintenance level, and with higher numbers concerned with a higher level, 20’s being direct support, 30’s being general support. ".
Other four digits are the Federal Supply Code, which can be found at
http://everyspec.com/FSC-CODE/ which are further broken down for some categories (usually designated by having a dash and a number for the sub-categories).
Like I said, it's all above my pay grade!
