First, I would like to say welcome aboard. I suggest searching the forums. There is a lot of infomation here. Helped me alot! I don't know if you have played SH3 but the U-boot tatical is pretty much the same. Finding range, AOB, and speed. Here is a link you might find usefull.

Your best bet is to search the forums and I am sure there are a couple of Captians in port the will help you out. Good luck and happy hunting.
