Redshirts

Redshirts is John Scalzi's Hugo Award-winning novel of the starship ensigns who were expendable...until they started comparing notes.
Tor Essentials presents new editions of science fiction and fantasy titles of proven merit and lasting value, each volume introduced by an appropriate literary figure.
Ensign Andrew Dahl has just been assigned to the Universal Union Capital Ship Intrepid, flagship of the Universal Union since the year 2456. It's a prestige posting, with the chance to serve on "Away Missions" alongside the starship's famous senior officers.
Life couldn't be better...until Andrew begins to realize that (1) every Away Mission involves a lethal confrontation with alien forces, (2) the ship's senior officers always survive these confrontations, and (3) sadly, at least one low-ranking crew member is invariably killed. Unsurprisingly, the savvier crew members belowdecks avoid Away Missions at all costs. Then Andrew stumbles on information that transforms his and his colleagues' understanding of what the starship Intrepid really is...and offers them a crazy, high-risk chance to save their own lives.
With a new introduction by Mary Robinette Kowal, author of the Hugo-winning The Calculating Stars.
