Strategic help

[Poliorcetes]

Ok, while having played lots of games I never used Strategic combat much. Now that I'm in an email game I find strategic combat very difficult. My fleets ignore space stations to bomb defenceless planets. I have a mixed fleet of bombers and torpedo ships. Everytime my leader ship shoots it moves away (good tactic), which makes every other ship in the formation turn away also (bad tactic). How do I get them to bLast the space station? I changed the capture planet tactics to include the disabled weapons option which I thought would make them stop bombing once the weapon platforms were destroyed . . . didn't work.

Can anyone give me some hints on how to use the strategies effectively with mixed fleets?
