The Desert Stove provided hot rations for the LRDG.
It was an efficient contraption that was simple to make. Take a canister and punch some holes in it for ventilation Next fill it with sand, if you can find some. Add petrol and light. A grill could be placed over top or more typically a pot could be placed right on top of the heated sand.
All the comforts of home without the home. Did you notice the trooper with the ladle is barefoot!
