This is the official Quartermaster's description of C-Rations used in Vietnam

"The Meal, Combat, Individual, is designed for issue as the tactical situation dictates, either in individual units as a meal or in multiples of three as a complete ration. Its characteristics emphasize utility, flexibility of use, and more variety of food components than were included in the Ration, Combat, Individual (C Ration) which it replaces. Twelve different menus are included in the specification.

Each menu contains: one canned meat item; one canned fruit, bread or dessert item; 
one B unit; an accessory packet containing cigarettes, matches, chewing gum, toilet paper, coffee, cream, sugar, and salt; and a spoon. Four can openers are provided in each case of 12 meals. Although the meat item can be eaten cold, it is more palatable when heated.

Each complete meal contains approximately 1200 calories. The daily ration of 3 meals provides approximately 3600 calories."

How to make a C-Ration Stove

The small cans included in the meal were ideal for making a stove. Using a "John Wayne" pierce a series of closely spaced holes around the top and bottom rims of the can. This stove was satisfactory, but did not allow enough oxygen to enter which caused incomplete burning of the blue Trioxin heat tablet, causing fumes which  irritated the eyes and respiratory tract. A whole heat tab had to be used.

A better stove was created by simply using the can opener end of a "church key" (a flat metal device designed to open soft drink and beer containers with a bottle opener on one end and can opener on the other commonly used before the invention of the pull tab and screw-off bottle top) to puncture triangular holes around the top and bottom rims of the can which resulted in a hotter fire and much less fumes. With this type of stove only half a Trioxin heat tab was needed to heat the meal and then the other half could be used to heat water for coffee or cocoa. A small chunk of C-4 explosive could also be  substituted for the Trioxin tablet for faster heating. It would burn hotter and was much better for heating water.

A stove was usually carried in the back pack or cargo pocket and used repeatedly until the metal began to fail.

How to Heat a C-Ration Meal

How to make a  C-Ration Coffee Cup

Obtain the B (large, dry) can from the C-ration meal 

Follow steps 2 thru 4 in How to Heat a C-Ration Meal above.

 

Remove the top of the can completely.

Obtain 2 lengths of the bailing wire off of the C-Ration case.

Obtain a solid, sturdy stick about 4 inches long.

Notch out a groove around the stick near both ends.

Wrap each length of wire around both top & bottom ends of the can and twist the wire around itself leaving enough twisted wire to twist around the grooves in both ends of the stick 1 inch from the can creating a very nice handle.

Trim off excess wire.
