Shooting incurs no fatigue?

[OmikronWarrior]

Actually, firing bows can be extraordinarily stressful. For example, the English Longbow is estimated to have 150-200 lb. of pressure, meaning firing it is like lifting that much weight with one arm. Archaelogy digs have found archer skeletons with deformed soldiers.

Obviously, these are the extreme examples, but Dominions does have longbowmen, and lesser bows are still going to have a large amount of pressure.
