you open the "C" or "T" pack, take the schnapps and the "Gauloise" cigarettes, throw all the rest (corned-beef, tuna fish, pâté...) to the trash or give it to a kid (there are always kids watching the tanks around a military exercise) and then you tell the people in the nearest village or farm that you're starving and they give you fresh bread, sausages, apple pies, beer cans

Well I admit it's not very well suited for real operations in an enemy territory or a commando operation, but anyway that's the French army...

I guess the legionnaires don't use this method, except for the beer!
