In Chapter 1 of the story Young Warrior by FantasyLover on SOL, there are discussions about the use of bows and arrows, among other weapons.
One of the characters (in olden times) using an orangewood bow can allegedly hit a target 400 paces away and still penetrate metal or thick wood armor enough to kill an enemy. I don't know how far 400 paces would have been at that time in that fictional place, but if it were 2 feet, 400 paces would be 800 feet (almost 3 football fields away). Today - for a fictional story based on realistic modern abilities, how feasible does any of that sound?
