The army used to use a "yukon stove" to heat it's 10 man and more tents.

It's essentially an "any" fuel stove. The tent must have an appropriate vent for the stove pipe to go through.

The stove itself is the height of simplicity. It's essentially a large steel box with fron legs, the back is supported by the stove pope which goes to the ground. If you are using kerosene or gas a burner is included as well as a fuel line. Fuel stays outside. Heats the tent rather nicely as I recall.

If you run out of liquid fuel, you take the burner out, close off the hole it sits in and you can burn wood,charcoal, coal, dirty sox, whatever.

The standard 5 gallon jerry can would last about a day if the stove was used minimally during the day and shut off about 8 at night. You more or less must have a fire guard awake and in the tent while the stove is in operation.

Not suited to backpacking. Weighs a ton, as does the fuel.
