Sure, we're all familiar with guerilla warfare, but what about guerilla coffee-making?

Three men who are Canadian soldiers in Afghanistan according to the video description (no patches or ID are visible on their uniforms) made an instructional short on how to make coffee in the field, using a boot strap, MRE supplies, guns and — perhaps most essential — sweet dance moves to "La Bamba."

"Step one: Adopt a firing position and make sure there's no f*cking insurgents around," they instruct. "Nothing f*cks up your coffee like f*cking insurgents."

Tips you wouldn't expect, among others: Use your gun to cool the boiling hot coffee!
