In the Medium Skirmish missions, the Serco Teradon seems to *refuse* to fire on the Itani Constellation. It will happily dispatch all the Tridents that come up to it, and the Itani Teradon has no problem with ripping Serco's Constellation apart. The Serco Teradon will just sit there, looking at the Itani Constellation.

This has happened in every Medium Skirmish I have tried.

I have noticed gaining full speed and knocking the Serco Teradon closer to the Itani Constellation gets it to start firing, but after a few seconds it backs up and stops firing.

This happens with Itani Teradons and Serco Connies s well. Sometimes you can ram them really hard to get them closer and they start firing, but it doesn't always work.
