A
punch in the eye’s not something you go out of your way to Fnd. Your M2A3/
M3A3 Bradley feels the same way when it comes to the commander’s remote
biocular display (RBD) being “punched” by the M242 chain gun.
Crewmen are sometimes leaving the feeder assembly’s feeder handle in the
unlocked position. That means whenever the gun is depressed, the corner of the
feeder handle hits the RBD.
BAM!
The
hit
is
hard
enough
to
damage the feeder handle and will
usually punch a hole in the RBD.
Then, as the nitrogen leaks out,
there’s nothing to keep moisture
from getting in.
Preventing
damage
is
easy.
Just make sure you
always
place
the gun elevation drive in manual
when accessing the feeder, power
cable or feed-and-eject chutes. And
never
depress or elevate the gun
when the handle is unlocked.
Don’t Forget the Cap!
With the hatch open, sunlight shines directly into the
lens. The light is magniFed and focused on the cathode ray
tube (CRT) faceplate, which then cracks from the heat.
Replace a missing or damaged lens cap with NSN
C
rewmen, taking care of the oil can points on your M992A2 ammo carrier is just as
important as any other lubing task. Just take the front and side APU door hinges,
for example.
Without lube, the pins inside those hinges will rust. Over time, they weaken and
can eventually snap. That could let the 210-lb door come
crashing down on you!
Keep those hinges strong and in the fight. Lube
them semiannually with OE/HDO like it says in
WP 0048 00-22 of TM 9-2350-372-10 (Mar 08).

Ain’t That a PunCh in the Eye?!

Wow!
where’ja
get that
shiner?
I bet it
wasn’t
from an
unlocked feeder handle!
Even if you keep the
RBD from becoming a
punching bag, it can
still
be damaged if
you don’t use its
lens cap.
