For fighting Spcaemonsters: Woody's guide
1. Use range to your advantage. They don't shoot back so the longer the range the better. Torps seem to do a better job than missiles in my experience
2. Use fighters and bombers because the monsters as far as I can tell don't damage them at all. Also, if the monster runs away (I don't think they are actually fleeing, but I have seen them move away and my ships can't keep up) the fighters and bombers can catch up and kill them!
3. Use overwhelming force! They can't hit you from range, so take overwhelming force and use it to kill them before they reach your ships, focus all fire on a single monster. Or, if you have found and reclaimed a hi-tech ship, sometimes it can take out a whole bunch of monsters by itself!
For Silvermists use Ion weapons, I *think* this is common knowledge, but just throwing it out there!
