As odd as it is, our best action right now is to pass this and destroy the OF in Occupation Authority, not in the space yard. If we are luckly, the OF here will destroy a ship that is worth 1 and we will not take a population loss, removing all the OF on the map.
The risk here is that that ship contains 2 pop, of course. 2 out of those 7 ships do.
(I will roll that when the actual destroying happens, right now I still have no idea.)
