A long while ago, I read a story that had a small group of villagers defending their town/planet against an invading force. When the troops showed up, they all just disappeared.
They had tunnels all through the town and were able to set up a guerrilla resistance and slowly overwhelm the troops until they holed up in a forest camp and were destroyed.
It was definitely sci-fi, but didn't use a whole ton of theming. It took place on a small planet (farming colony maybe?). The troops came in on dropships from space. Unfortunately I can't remember a lot more.
Anyone know what it may have been called / who wrote it?
I read it probably 5-10 years ago, though I don't know the age of the story itself. And it was a short story, not a novel.
Just remembered something else... the story opens (and closes) with an older gentleman on a hill overlooking the town casually cleaning his laser(?) rifle and then making his way off-scene with a hovercraft. (I remember both he and the other townspeople not actually being that concerned, just kind of dealing with it as though it was a storm or something.)
