Hi shipmates. This is my first post so please don't laugh if I seem like a complete moron. The thing is that I cant find out what the little "N" symbol means on some of my "Sub" units. I know what the "x"and"g" symbols mean but not the "N". Also some of my aircraft on patrol missions seem to circle around one spot and the unit status window declares that they are waiting. Waiting for what? Help would be gratefully received thanks.
