“Don’t fold it” is what every NBC NCO
should be telling his unit about their M40
and M42 masks.
Many soldiers are folding their masks
when they put them in the carriers. But
folding shears the drink tube coupling and
pokes holes in the facepiece. Then the mask
is ruined. Inspections at some posts have
found as many as 40 percent of masks are
ruined.
The folding culprits seem not to be young sol-
diers, but the veterans who started out with the
M17 and M24 masks, which were folded for stor-
age. They forget it’s a different story with the
M40 and M42.
So, NBC NCOs, tell your soldiers—especially
the older ones—”Please don’t fold” and show them
these procedures for storing the M40 and M42.
Make your job easier by copying this ar-
ticle and giving everyone a copy.
