I don't know about you guys, but I rarely use military star bases. They are usually not worth the micromanagement. However in my current game, the Thalans quickly decided to attack me, because they thought I was too weak to be a 'worthy neighbor'. And they were right, my military was pitiful compared to theirs, and their fleets were already on the way. In an act of desperation, I built a military star base in the corridor they would come through and equipped it with some assisting modules for my ships. It was then that I noticed a new module I hadn't seen before, the 'Warp Field Inhibitor', which gives a -2 to enemy ships speed. That alone is not a big deal, but combine that with the Yor's ability (which I was playing this game) as a super isolator, which reduces enemy ship speed to 3, and you get instant space molasses, enemy ships can only move one square per round. This makes it easy to pick the weaker fleets and buys you lots of time. Only have to constructors ready and you can slow down an enemy advance wherever you want.

Anybody else ever used this tactic?
