The man in front was hired to dispose of our fecal waste by burning it. This act required a precise mixture of gasoline, diesel and semi-liquid waste. This was base camp 'shit' with solids and was difficult to burn. This job was my specialty in our field battery.
Papa San did not return to work after a failed and costly enemy attack on Tay Ninh base camp; few if any of the shit burners returned to work after that.
