Why isn't the numbering of all the Regulations, Field Manuals, Guides, TMs and etc sequential?

Don't know about the TMs but there's a DoD Standard Subject Identifier (SSI). It basically lists the numbers you're supposed to use in preparing letters, instructions, etc. Doesn't cover everything.

Mainly because each series covers a specific set of areas. For example, in the Air Force, the 36-Series of publications covers all matters personnel. 36-2903 is the Air Force Instruction for Dress and Appearance of Military Personnel, 36-2201 covers training.

They are broken down by subject areas?

They use a filing system as opposed to a sequential system. #XXXX revA dtd DDMMYYYY. This means that unless superceded by a more tailored (smaller) or a broader (larger) Manual or Reg, you will always be able to find it.

It gets convoluted when you get into regs because they apply to specific areas, so the numbering is more akin to the Dewey Decimal System. Reg X applies to something particular so it has number 6-X, while reg Y applies to something else getting 6-Y.

The codes used designate very specific pieces of information. In theory every piece of correspondence produced from Memo to Manual will have "a" code on it, so that we know how to file it.

Manual Numbering System (U.S.War Department 1944)

a. The basic number will be as follows: 1. Army Air Forces. 2. Cavalry. 3. Chemical Warfare Service. 4. Coast Artillery Corps. 5. Corps of Engineers. 6. Field Artillery. 7. Infantry. 8. Medical Department. 9. Ordnance Department

There is a method to the madness, see: DA PAM 25–40 Army Publishing Program Procedures, Chapter 8 Numbering and Indexing Publications
