Corrected entry: In the finale battle at the Black Gates, the good army is in a tight group surrounded by 10,000 orcs. If just 1/3 of those orcs had bows (which we never see in the final battle), and they volleyed into the group, 3000 men would have died right there (if not everyone, including Aragorn, Gandalf, the hobbits, etc). In all three films, the evil side has some sort of bowmen, but for some magical reason the army protecting the great eye and the orcs' leader, seems to have conveniently forgotten their bows. (Regardless of anyone's feelings, its a logical winning move for the orc, one that someone (PJ) left out, and no trees in Mordor to make bows is not a correction.)

Correction: Sauron is arrogant. He assumes there is no need for bows. He takes pleasure in causing suffering and so do the orcs. The orcs would have preferred to kill the intruders in combat rather than at range, Sauron would rather watch them be killed by ravaging orcs instead of an arrow, and "10,000" orcs should be more than enough to easily kill each and every one of these intruders. And, indeed, they would have been if the Ring had not been destroyed in time.
