These were usually dug into trenches and the Army Catering Corps would do their thing. Picture from B.A.O.R. Photos.
Known as a kettle trench. Before the Stove, No.1 shown above the 3 gallon dixie was the standard cooking pot for the British army. A narrow trench would be dug, a fire laid in the trench and a number of dixies set across the trench to heat. If front line troops were being served the hot dixies would be carried forward by ration parties, a duty roundly hated by all involved. Alternatively two pieces of railroad rail would be set next to each other to act as the trench and the dixies set across those. The dixie was in use from before WWI until well after WWII, perhaps into the 60's or 70's.
These 3 gallon dixies were also used by the Belgian army after WW2, but they were made from tinned sheet. I would very much prefer the cast aluminium ones!
