ou’ve closed the cargo hatch on
your Bradley. Why, then, is the OPEN
HATCH warning light on the driver’s
panel still on?
Bradley Tarp
C
rewmen, using the green tarp listed in Appendix B of the Bradley’s -10-1
TMs is like painting a bull’s-eye on your tan-colored vehicle. Keep your
camouflage intact by ordering a tan-colored tarp with NSN 2540-01-330-8062.
ow that you’ve finished bore-
sighting the cannon on your M1-
series tank with the M26A1/M27A1
muzzle boresight device (MBD), it’s
time to hit some targets.
Oops! Don’t forget to remove the
MBD!
Some really bad things can happen
if you fire the gun with the MBD still
in the tube. You can damage the
MBD, the gun and other equipment.
If the blast is strong enough to dam-
age the breech, it can even injure or
kill you or your fellow tankers!
So, don’t rely on your memory.
Use
the red warning flag
that comes with
the MBD. Tie it to the optical unit. A
red flag swinging in the breeze will
catch your attention. It’ll also alert
M2/M3-Series Bradleys . . .
M1-Series Tanks . . .
Flag missing? The one that comes with
the MBD isn’t available in the supply
system, but you can order a suitable
replacement flag with NSN 8345-00-
181-3951. It measures 24x3 inches, but
isn’t marked “REMOVE AFTER
BORESIGHTING” like the original.
As a second check, always take a peek
through the breech before loading a
round.
Before you call your mechanic, take
a close look at the cargo hatch. Look
for dirt and sand that may have built
up on the cargo hatch seal.
Enough dirt and sand can keep the
hatch from closing properly. It’ll shut
if you slam it hard enough, but the
hatch sensor still thinks it’s open.
Clean out the debris and close the
hatch again. If the light still won’t go
off, call your mechanic.
