T
he M205 tripod will soon replace the M3 tripod. Unfortunately, a general safety warning
was left out of the M205’s TM 9-1005-437-13&P.
The most recent edition of the TM adds the caution. You can download the TM at:
WARNING
PINCH HAZARD
Use caution when placing hand or fingers near tripod pinch points. Keep hand and
fingers clear of pinch points when releasing leg(s). The operator must wear gloves
during SETUP and BREAKDOWN. Failure to comply may result in pinching bare fingers.
Seek medical attention if necessary.
M
ortars use sighting devices that contain radioactive tritium. If one of these devices
gets banged around and broken, the tritium can leak out. That poses a health risk if it
gets on your skin. Plus, any radiation leakage must be reported to the local radiation
safety ofFcer.
So it’s in your best interest to do
everything possible to protect all
components containing tritium. That’s
not as much of a problem when it
comes to the M64A1/M67 sight units
and the M58/M59 aiming post lights.
They have hard cases you can keep
them in when they’re not being used.
But things get trickier with the 60mm cannon tube. Its range indicator contains four
separate tritium lamps. If it’s left unprotected and unsecured in the back of the truck,
it can roll around and get banged up by other equipment. It doesn’t take too big a blow
to break one of those lamps.
So before you hit the road, make sure
the 60mm cannon tube is secured so it
can’t roll every which way. If possible,
give the range indicator extra protec-
tion by wrapping it in bubble wrap or
a blanket.
If one of the range indicator lamps fails
to light up, something is wrong. You need
to report it to your radiation safety ofFcer.

Dear Half-Mast,
The new M249 TM 9-1005-
201-23&P (Apr 13) does not
show the same configuration
for the pistol grip as the
previous version did.
Fig C-7 in the old version
showed the pistol grip, NSN
pin, NSN 5315-01-309-
7192; and the locking plate
assembly, NSN 1005-01-
131-1911. Fig 8 in the new
version shows only the pistol
grip. Is this a mistake?
SGT M.S.
Dear Sergeant M.S.,
No, it’s not a mistake.
The pin and locking
plate assembly are no
longer part of the pistol
grip. You need only the
pistol grip.
