Meh, when I'm on the field doing army stuff, I carry 2 canteens each holding about a quart, neither of which are particularly heavy or burdensome at all. So at any one time I'm carrying half a gallon, I imagine that would be enough to do some basic, emergency maneuvers, or like... make a water whip.Edit: I think half a gallon is only something like 4 pounds

This is true. Back when I used to go backpacking a lot, it wasn't uncommon to carry a gallon or two, depending on distance and availability of water. At the same time though, it might be a tad inconvenient. We'll see though.
