Can't Kamikaze!

[Nitram Draw]

Are they attack ships?
I had problems with my PD ships staying in formation until I added a weapon. Plus I had called them a defense ship.
It's wierd how certain components seem to affect the strategy. It would seem to me that the strategy should override all other factors when determining how the ship acts.
Maybe you can find the cure in the formation or strategy files. I never look at them cause I don't have a clue how they work.
