I have a MSR Sweetwater and a good idea of where the local water can be found.
That's what makes us guerillas instead of just soldiers. We can operate in our backyards and survive in areas where the enemy can't. If we blow up a water tanker, that is one thing. But if we get our water from rivers and streams, seepages and wells, we're far ahead of an enemy which must ship in reliable water.
