I heard a story once about some US servicemen using surplus fuel to burn out the pit under their latrines in order to “freshen them up”. Apparently an officer didn’t want to listen to the advice of an enlisted man, and was sitting in the outhouse when the fuel was lit. He too ran out with his shorts around his knees.
We used that method in Vietnam - on a daily basis, the local sanitation engineers would pull the container (made by cutting a 55 gal. barrel in half) from under the latrine, pour a cup of diesel fuel on top and light it. There was often little clearance underneath the seat so you made sure your equipment was not hanging down when the barrel was pulled....the edges were ragged and sharp.
