That wasn't about moly - it was only about anti-seize on brake slides.

I think the first time I heard about it was from an instructor at 11MC2 school (Bradley IFV crewman) back in the mid 90s, I guess. The specified grease for part of the Bushmaster's receiver or feeder was GMD which stands for "grease, molybdenum disulfide". But he said it stood for "grease'll makeya dead" because of its toxicity, and because he had trouble pronouncing the chemical names. Ford used to (as late as '89) specify the same grease for speedo cables & several other general maintenance items, but now recommends PTFE in old speedo cables.

I only just thought of digging up an MSDS for it, and although I haven't found one for the grease version yet, I found these for the powder:
