Here's a few excerpts from the Navy Mess Management Specialist training manual:
Gasoline field range outfits are the most satisfactory appliances available for preparing meals in the field. The armed forces now use model M59. Chapter 10 of the Basic Doctrine for Army Field Feeding, FM 10-23, covers the operation of the model M59 field range. Operator, Organizational and Direct Support Maintenance Manual including Repair Parts and Special Tools List for Range Outfit Field, Gasoline, Model M59, TM 10-7360-204-13&P, covers the maintenance and repair of model M59.
One field range is adequate for 50 personnel or less. With two ranges, you can cook for 50 to 100 personnel. With three ranges, you can cook for as many as 225 people.
The gasoline field range outfit is designed to provide a complete outfit adaptable to the different requirements of field operations. The outfit consists of a cabinet with a burner unit, accessory outfit, and necessary cooking utensils. The outfit is portable and can be operated while in transit.
The range outfit can be used for boiling, roasting, frying and griddle cooking and can be adjusted to work as a bake oven. Some baking can be done in the covered roasting pan or in the cake pan placed inside the covered roasting pan. Pies bake well in the roasting pan alone. However, for all other baked foods, you should use the cake pan. If you do a great deal of baking with the range, make the necessary adaptation.
