our M1’s laser rangerfnder (LRF) is essential when you’re engaging an enemy
target or per±ecting your gunnery skills on the range. But, without precautions, the
LRF can deliver a potentially blinding laser hit to your ±ellow Soldiers.
I± your tank is equipped with a non-eye sa±e laser, NSN 1240-01-264-2040 or
1240-01-381-5086, remember to always do the ±ollowing two things:
1.
Install the eye-sa±e flter, NSN 1015-01-234-8165, on the LRF. This’ll protect
Soldiers ±rom eye damage in case the LRF is activated by accident.
You can tell i± the flter’s
installed by the green tag that
hangs out o± the LRF.
2.
Make sure to put the sa±ety
guard,
NSN
5930-01-171-
4788, back in place on the
LRF once the mission’s done.
The
sa±ety
guard
makes sure the LRF isn’t
accidentally
armed
while
you’re moving around inside
the
tight
confnes
o±
the
turret. The sa±ety guard keeps
the LRF switch ±rom being
accidentally moved.
There’s no need ±or the flter and sa±ety guard i± your tank has an eye-sa±e laser,
Dear Half-Mast,
Our mechanics are
finding that the oil filter,
NSN 2940-01-197-
7106, called for in the
M113A3’s TM 9-2350-
277-24P, can fail.
When taking M113A3s
for a road test after a
scheduled service, we’ve
experienced several oil
filter seals that have
blown, causing a real
HAZMAT mess and
requiring a tow back to
the shop for repair.
We’ve found a different
oil filter, NSN 2940-01-
314-1345, that doesn’t
seem to have any problems.
Is it OK to use?
SGT C.S.
Dear Sergeant C.S.,
Don’t use the substitute oil flter. Only use
the oil flter called For in the TM. IF that flter
has a soFt rubber gasket rather than a hard
one, it’s likely a bad flter. Don’t use it.
The best way to correct this problem is by
submitting a PQDR. Go to:
Once there, click on EZ PDR Logon in the
leFt-hand column, log in with your CAC and
Follow the instructions. Make sure you hold on
to the flter and packaging. It may be needed
as part oF the investigation.
