f your Avenger Missile System's identi-
fication friend or foe (IFF) is not accu-
rate, the consequences could be tragic.
Many units aren't sure how to test the
accuracy of the IFF, so it doesn't get
checked. Help is now at hand in the form
of a training videotape.
The tape shows you how to check to
IFF and contains the codes for running
the checks. Your COMSEC custodian
will need to order the tape, AKZT-3662,
because it's a controlled item.

Dear Editor,
We have some suggestions for Patriot crews that should keep their
launchers launching longer.
ECU/PPU
needs
O-r
ing
A
venger repairmen, every time the
valve cover on the environmental
control unit/primary power unit
(ECU/PPU) is taken off the cover's
O-ring must be replaced. The O-ring
is not reusable. If the old one is used
again, you risk oil leaks and damage
to the ECU/PPU.
But it looks like the O-ring is not
being replaced. Defense Supply
Center-Philadelphia (S9I), which
manages the O-ring, reports there has
been zero demand for the O-ring.
Because the ECU/PPU tappets are
supposed to be adjusted at least twice
a year, the O-rings should also be
replaced at least every 6 months.
Order the O-ring with NSN 5331-
01-400-5772.
O-ring must be
replaced every
time valve cover
is taken off
gosh, I
can’t tell if
those are
good guys
or bad
guys!

When you drain the launcher's
M860A1 trailer air tanks, pull the
handle straight back. If you twist the
handle as you pull it back, you can
break the handle's cable. That cable
is very difficult to replace.
•
The GPS (global positioning
system) antenna cable is
fragile. If you just jam the
GPS in its storage box, you
damage the cable and you
have no GPS. Avoid that
problem by pushing the cable
to the side before putting the
GPS in the box.
