A HERCulean Bestiary:

Everyone has their favorite combination of HERC's and weapons. I've found the following set to work well in most situations. You may want to make modifications to the weapons list depending on the particular mission you're going on, such as loading up on precision weapons for salvage runs, or snapping on a missile pack or three if you know you're going to be up against flyers.
