War is an extremely common backdrop, setting, and storyline for almost every genre of fiction, but sci-fi war is often the most spectacular and the most vicious.

Lengthy loving descriptions of fantastical orbital lasers, heat-seeking antipersonnel rail guns, or existential weaponry that erases the victim's place in time fill the genre. Thankfully, there is one time-honored way to turn a character into one of those exquisitely tuned killing machines.
