Here's another interesting tidbit...........I was on a planetary assau;lt mission, and I got in real close to the planet with my Coventry and Ptolemy Battle Tug and started pounding the planet with photons and suicide shuttles and phasers, which was quite fun of course. But then all of a sudden some (I think) Phaser-4's started firing presumably from the planet and destroyed my Coventry. Howevr.....the strange thing is......on the status display, the planet showed as having no weapons. If it had had weapons I'd have taken them out, first thing I did.
Do some planets have "hidden" batteries that you can't target?
