A well-conceived and well-written short story which apparently sets up a great series. This is a good way to set the hook: a self-contained story which introduces the setting and perhaps the characters of the greater tale. The reader know what she is, and isn’t, getting.
“Centuries of warfare in the electronic age …”
That said, it reads as if it takes place late in this century, not two hundred years or more into the future. The weapons are current or under development. The technology and electronics is nothing beyond the reach of current science. In fact, the tactics—a “ground” assault on a space platform—seem incredibly archaic. I know space operas thrive on grand battles and fleet engagements, but it strikes as a failure of imagination to have nineteenth and twentieth century forms of warfare the norm.
“With the same information, I’d do it again.”
The issue of culpability is as old as mankind. Even folks who came back from “good wars”, like World War II and the 1991 Gulf War, have regrets and misgivings about the tactics employed to achieve the ends. Our protagonist earned the skeletons in his closet. For readers who have no engaged in combat or combat support, it’s a good stretch of their minds.
Nice set up for future reading.
