Dear Editor,
We support the Bradley units at Ft Carson. We have run into a couple of
mistakes crews are making that can seriously hurt the Bradley’s accuracy:
Not using TM for collimating.
When operators do the boresighting
and zeroing procedures, they can follow the steps on the commander’s
tactical display,
except
for collimating the borescope to the M242 barrel.
To boresight correctly, you must follow the procedure in WP 0018 through
0020 in TM 9-2350-293-10 (Dec 01). Many times they don’t have the
-10, so collimating is done wrong or not at all.
It’s critical
that you keep
a current copy
of the TM in
the Bradley
at all times.
That way the
procedure
will always be
handy.
Use hand station for last M242 zeroing step.
To zero the
M242, you are supposed to hand crank the turret until the M242 is lined
up with the target. Shoot one round. If the reticle jumps off target, use the
crank to put the reticle back on target. Then push AIM POINT and use the
hand station to align the reticle with the round’s point of impact.
The problem is that crews use
the crank instead of the hand
station to do that last step. The
M242 isn’t really zeroed as a
result. All they need to remember
is to use the hand station for
the final step to get it right.
Crews can find the correct
procedure in Para B-77 in FM
3-20-1,
HBC Gunnery Manual,
which explains how to zero the
improved Bradley Acquisition
System (IBAS) to the M242.

Editor’s note:
Bradley
crews should zero in on your
zeroing tips. Thanks, guys.
Dear Editor,
I’m writing to let your readers
know there was a problem with
a posted MWO for the Bradley
in the Modification Management
Information System (MMIS).
The MMIS site listed MWO
9-2350-373-50-2 for the
Bradley. But this MWO was only a
draft, so if you printed it out for
use, get rid of it. The correct mod
is MWO 9-2350-294-50-2.
You won’t find the correct MWO
in the Bradley’s EM 0043 or on
the LOGSA ETM website, but it’ll
be added in the next revision.

Editor’s note:
Thanks for writing
in. That will keep Bradley units from
making the wrong modiFcations to
their vehicles.

how did I
miss
that
bad?
but
they
zeroed
you
wrong.
hope you
brought
a current
copy of
the TM!
hey
what’s
wrong
with you?
you look
terrible!
somebody used
the wrong mwo for
me and now I don’t
feel so good!
I don’t want
you doing the
collimating
procedure
from
memory.
my crew
zeroed
me.
