Second hand story from a plumber I know, who is buddies with a Frozen Chosin veteran.....
A marine unit "attacking in a different direction" needed a resupply of bazooka ammunition. Each round came in a black cardboard tube, and was nicknamed "Tootsie Rolls" for the similar appearance. The moral of the story is "Somebody never gets the word". The Air Force conducted a parachute drop of two pallets of ammunition. Except it wasn't ammunition, it was actually two pallets full of tootsie rolls. I understand that some new curse words and comments on Air Force heritage were invented that day.
However, the tootsie rolls were put to good use. Placed under an armpit for a while, they warm up and become a source of calories which you can eat quite easily on the move. And the pallets are good firewood, albeit not so portable.
For the record, chocolaty tootsie rolls are not especially effective at stopping Chinese tanks.
Rest in peace Marine. You are not forgotten.
