Dear Editor,
According to AR 25-30,
Army Publishing Program, units are supposed to have one operator’s TM for each piece of equipment. But because the M50/M51 protective mask’s
TM 3-4240-542-13&P is around 350 pages, that’s not practical. So the Army has issued a waiver for the M50/M51.
Units need only two copies of the TM. The TM is available on the AESIP/LIW’s ETM site:
But they do need a set of operator cards, NSN 7690-01-529-1398, for each mask.
Please spread the word about this.
