ust, sand and dirt are obvious dangers to your combat vehicle’s air flters. But
water can be just as big oF a hazard.
IF it’s cold out, wet flters
can Freeze and plug up,
keeping the engine From
getting the air it needs to
work. That can lead to a
burned-out engine.
So take steps to keep
those air flters as dry as
possible. When the vehicle
is
sitting,
cover
the
air
cleaner intake with canvas
or plastic to keep out rain,
sleet and snow. Just be sure
to remove the cover beFore
starting the vehicle.
Keep a close eye on the
air cleaner indicator or air
flter clogged light while
operating your vehicle. IF
the element gets plugged,
it needs to be cleaned, dried
out or replaced—whichever
is
needed—as
soon
as
possible.

Dear Editor,
We have discovered that FM 3-20.21,
Heavy Brigade Combat Team
Gunnery,
can make getting your Bradley ready for action much simpler.
Appendix B gives all sorts of information on boresighting, troubleshooting
and zeroing the Bradley’s guns. But what is particularly helpful is Para B-72,
which has a pre-fire checklist for the gunner and vehicle commander. The
checklist will ensure the Bradley is ready to shoot.
