I've decided that their destruction is absolutely essential to a successful from-sea-invasion. However, when I went to try it, my fighters would merely destroy farms and such; rails and roads were untouched, and when there were nothing but those left on a tile I couldn't target it anymore.
Are rails and roads immune to destruction or something? Or am I doing something wrong?
The reason I feel I must do this is because in my first several games entire stacks of advanced units were wiped out by enemy primitives merely by virtue of numbers. The AI just seems to have so many freaking units, huge stacks in each city. And when invaded, every single one of those stacks can all attack a single tile simultaneously if they have rails. So I must destroy them, a buffer zone of about 2 tiles.
EDIT: NOTE: when I tested it, I was only targeting roads; the enemy hadn't built any rails by then.
