Equipment technical bulletins are numbered in the same manner as equipment technical manuals. In
TB 9-1005-226-12, for example, "9" is the series number, "1005" is the FSC, "226" is the bulletin
identifier, and "12" is the category of maintenance. If there is more than one bulletin on a specific item
or piece of equipment, another number is added to the series. For example, TB 9-1005-226-12-2
indicates the second bulletin in a series.
As an ammunition officer, you must pay special attention to the warnings, cautions, and notes in
technical publications. Warnings and cautions appear just before the text to which they apply. Notes
usually follow the related text. Every technical manual, technical bulletin, or supply bulletin that
contains warnings or cautions has a warning page inside the front cover or in the front matter of the
Warnings are instructions that you must follow to avoid the injury or death of personnel. An example of
a warning is shown in Figure 1-4.

Cautions are instructions that you must follow to avoid damaging or destroying equipment. For
example, certain test procedures require that cable connections be made in a specific order. An
example of a caution is shown in Figure 1-5.
