In Star Trek New Worlds Klingon Mission 3: Into The Arena, you play the klingon side of a mission we saw in the federation campaign.
The Taubat have switched sides. They no longer wish to give the Klingon Empire planets even after the empired helped them with their internal rebellion. To respond to this, you must destroy their entire base on this planet. It is defended heavily by distruptor turrets - use artillery to knock them out. To add insult to injury, capture their power facility and take whatever you need. The Federation and Romulans are on this planet too, don't fire on them unless you are fired on first.
