GUN:  Gun system, which may vary according to the ship firing ("Ctrl-F9")

CIWS:  Close-In Weapon System ("Ctrl-F10")
You can control whether or not a friendly asset uses any, all or a 
combination of the weapon systems available to it. To toggle a weapon 
system on or off for the currently hooked target, enter "Ctrl-F1" through 
"Ctrl-F10" as shown above, or click on the weapon text. 

     NOTE:  Beginner-level players can use the same controls for enemy 
assets.
