The Bougainville Resistance Army.

"The most extraordinary aspect of the BRA’s resistance was the use it made of Bougainville’s erstwhile staple crop: the coconut.

Islanders ate its flesh, drank its milk and sealed their wounds with its leaves. They wove it into baskets and homes, burned it to ward off mosquitoes and even made music from the husks. 

They cooked with it and cleaned their guns with its oil, boiled it into soap, and when they fermented and cooked it, they distilled a fuel that yielded double the mileage of regular diesel.
