the hellfire
missiles
misfired
because
they
weren't protected
during
transport
.
“
the seeker head
s
were
scratched
,
ruining
the
g
uidance
s
ystem
. this can
be prevented
by keeping
missiles in
s
torage
c
ontainers
during
t
ransport
a
nd
in the field
."
“
after connecting
the missile to the
launcher,
clean
the seeker
with a
soft
lint-free
c
loth
slightly
dampened
with
isopropyl
alcohol
. let
it
air dry
."
sir, we've gotten
word the monster has
settled
beneath the city
and seems to be
resting
.
sounds
like an
opportunity
to get
caught up
on
pm
, sir.
yes!
direct hits
! the
mlrs
and
tank crews
have the monster
reeling
, sir.
send in the
apaches
to
finish
it off
!
i just took a look
at the units involved, sir.
their
equipment
just
wasn't
ready
.
what
do you
mean?
the missiles on
each mlrs would not
fire because the vehicles'
launcher/loader
module
(llm)
batteries
were
dead
.
that explains
that
problem. but what
about the
tanks
?
this can be
prevented
by
wiping down
the ammo
compartment as part of
before operation pmcs
and by placing bags
of
desiccant
, nsn
in the ammo
compartment.
the ammo
wouldn't fire
because it was
corroded
.
water
from
condensation
in
the
ammo
compartments
was the
culprit
.
you heard the
master sergeant
!
i want every soldier
doing pm
!
pronto!
“
before
going
to the field,
they should hav
e
checked the
electrolyte
in
each
of the
10 batteries
.
its level should
be
above
the
plates
on each
battery."
“
they also should
have wiped off any
dirt
or
corrosion
o
n the
battery
c
onnectors
with a
clean
c
loth
, then
checked the
c
onnectors
for
tightness
by
g
ently twisting
the
clamp
. it
s
houldn't move
."
a while
later.
