Editing Siege Weapon (section)

===Hwacha===
A Korean gunpowder weapon used defensively against large armies. Take a bunch of long arrows, attach small rockets to each arrow, load each of them in a tube, stack the tubes tightly in an open frame, and fire all of them at once out of a portable box container on a fixed cart. A single launcher could fire as many as 200 arrows. Such overwhelming firepower made attackers think twice about charging defensive positions. While reloading them was a time consuming nightmare, they served as a good psychological deterrent and volley weapon from defensive positions.
