T
ry to remember that when you’re getting ready for the next hot turn-around. Yes,
there’s plenty of danger outside the wire, but what about the risk you’re taking if you
don’t do PM?
That HMMWV or Bradley you’re driving or commanding or riding in is only as
good as its maintenance—and someone has to do that PM. If it’s your neck on the
line on patrol or in a convoy, it ought to be you.
It’s tough enough out there without making more problems for yourself. Since
you gear up with the most protection you can get before you go on duty, doesn’t it
compute that your vehicle needs the most protection you can give it?
Your vehicle does its job protecting you from external threats, but the only pro-
tection your vehicle has from internal threats is YOU!
Did you check
oil levels in the
engine and
transmission
before
you tore
out the gate?
Do you want to
get miles from
nowhere and
have your vehicle
become a sitting
target because
there was
no
oil
in it?
What
other
little things do
you let slide
because it’s
late or you’re
in a hurry?
Are you going
to bet
your
life
on the
chance that
someone else
has made those
last-minute
checks?
you
bet!
heck
no!
not a
one!
no way!
You
Must
Do PM!
