Dear Half-Mast,
In the latest version of TM 9-
2320-387-10, Item 5 of the weekly
PMCS says that a bad door will make
your HMMWV NMC. Why is a canvas
door considered an NMC item? Does
the truck headshed really mean that
bad ballistic and up-armored doors
make the vehicle NMC?
SPC. A.S.
Dear SPC. A.S.,
You’re right. That
is
what
TACOM LCMC meant. They will
include the correct information in
a future TM update. Until then,
note these comments from the
HMMWV maintenance experts:

{Whew!}

is getting
harder and
harder to
close!
that’s
weird…
based on the
operator’s
manual,
your door is
good.
OUCH!
there’s
some
new
NMC

my doors is super
hard to close.
