We had little "petrol" cookers that were supposed to used to make the contents of the famous "Ten Man" ration pack "edible"

Pump them up like an old-time plumber's blowtorch or "pressure lantern" and they got hot REALLY fast.

Then, all of a sudden (ish) they were a problem. EVERYTHING started being run on DIESEL fuel.

You could huff and puff as much as you liked, but those little stoves WOULD NOT work with that stuff.

Next thing, the "fashionable" Digger was sporting a variety of Gucci, camping-store-bought, gas cookers which may just be a bit of a liability on the two-way rifle range.

The good old Hexamine solid-fuel cooker still works fine; even finer if you have friends in low places (Assault Pioneers, Engineers) who have C4 to spare. It burns VERY hot, makes a brew REALLY FAST, but also burns the bottom out of the flimsy, folded tin-plate stoves VERY fast. Was always advised to NEVER douse burning C4 by tipping it on the ground and stamping a big boot on it.
