Hwacha

Since rocket launchers are now official I was thinking maybe they could add in the Hwacha. If you do not know that that is here is the wikipedia http://en.wikipedia.org/wiki/Hwacha. It would be cool to have these in game think about a group trying to raid another base and they want artillery cover so they station one of these onto a rock with a player reloading and firing it while the others are able to charge.
