Seconded. I suggest putting this in the actual suggestion thread and creating a link to this conversation (steve reads these less frequently than the 50 page suggested thread, amazingly)
Once you build up your schools, you get hundreds of officers-- and you don't always need them all. I'd like to filter out and fire all the bad scientists and perhaps clear out the lousy officers and civilian administrators, in bulk, periodically. Simply because the game is tracking their promotions and I'd be amazed if that isn't a contributing factor to late game slowdown. I think it would be better for standard officers to be hired as needed depending on the level of academies available.
