As a soldier you must be creative if you want hot food.
We have also made sausages and bread in aluminum foil fastened to the manifold on a Mercedes GD. You donīt have to drive many miles before you have lovely roasted sausages.
Or you can put canned food beside the oil burner in a M-113 APC. It works quite well - a little too well actually. The first time we tried, it went wrong. The can exploded with a big bang and the entire vehicle inside and every man was covered in spaghetti with meatballs. The
vehicle commander did not think it was funny.
