My TT 3 day assault pack will carry more that I probably would want to, especially with all the extra pouches/bags I could attach to it. I would probably start out with a web belt containing 2 one quart GI canteens and a two quarter. I would also have a knife on that belt. Plus I would possibly have a 1 lit SS bottle in each side pocket, or at least one in the Maxped water carrier I acquired. The pack I would fill with clothes, another pair of boots, food and other items needed (ammo for one).
