M120/M121 Mortar…
B
ecause three soldiers recently lost their lives during misfire removals with the
M120/M121 mortar, the misfire and PMCS procedures have been changed by
Change 3 to TM 9-1015-250-10. If you haven't seen the new procedures, see Pages
22-25 in PS 601 (Dec 02) or ask your TACOM logistics assistance representative to
get you a copy. The article is on the Internet at:

Part of MWO 9-1015-250-30-2 is to
add warning decals to the M120/M121
that say: WARNING! SET SELECTOR
LEVER TO SAFE BEFORE ATTEMPT-
ING
TO
EXTRACT
MISFIRED
ROUND. The decals should be put on the
cartridge extractor, on each side of the
carrier ammo racks, on the rifle rack, and
on the underside of the step lid. The decal
shows the proper setting for SAFE.
If you haven't gotten the decals or you have missing or damaged decals, contact
your TACOM LAR or call TACOM-Rock Island's Joe Schmidt at DSN 793-
3369/(309) 782-3369 or James Hayes at DSN 793-3229/(309) 782-3229 or email:
TACOM-RI-Mortar-Systems@ria.army.mil
MWO 9-1015-250-30-2 also explains where to put the decals on your mortar and
TB 9-1015-250-30-1 shows how to replace damaged decals. Your TACOM LAR or
TACOM-Rock Island can get you both publications.
