Now speaking of reality, have any of you ever worked in the trades (carpentry, electrical, plumbing, etc) and had to wear steel toed work boots, a tool belt, leather gloves, and a hard hat all day? I have (was an electrician for 12 years) and let me tell you, I am not going to walk 5 miles through the forest, run from a pack of wolves, and then get in a fight at the local tavern wearing all that. Now add to that a heavy winter coat, a backpack with a mild load of 30lbs of gear, while carrying a big baseball bat and a garbage can lid.
Closest to reality might be our soldiers that go to battle. They might carry (generally speaking) a rifle with spare ammo, a 60lb pack that includes a 2-4 liter water bladder (water weighs 8lbs per gallon), wear a flak vest, helmet, a bowie knife, and combat boots. That's a mighty heavy load but does not even come close to approaching DDO loads.
