nowing about BII, COEI, and AAL can make all the difference when
you’re trying to figure out what item your unit needs and how to order it. Here’s
a primer:
Basic Issue Items (
BII
) are items your
unit
must
have to support and maintain an
end item—screwdrivers, TMs and grease
guns are usually BII. BII stay with the equip-
ment at all times, even when you turn it in.
Your -10 TM is the authority for ordering
BII based on your unit’s TOE/MTOE.
Components of End Item (
COEI
) are
parts of the end item that are packed sepa-
rately. COEI also stay with the end item if
it’s turned in. The short antenna for the AN/
PRC-126 radio set is an example of COEI.
COEI are listed in your -10 TM only
so you will have the information if you
need to order replacements. That’s the only
time you order COEI—when you need a
replacement.
Your -10 TM is not an authority for or-
dering COEI. Your authority is the parts
manual in which the item is listed.
Additional Authorization List (
AAL
)
items are things like cable assemblies and
batteries that support an end item. AAL
items may stay with your unit when the end
item is turned in. The ordering authority for
AAL is a CTA, MTOE, TDA or JTA.
Expendable/durable supplies and materi-
als are things like rags, lens paper and
lubricants that you need for taking care of
an end item. You get to keep these. The
authority to order them is CTA 50-970 or
CTA 8-100 (Medical).
