The best military science fiction & fantasy books by veterans

Heinlein, who served in the Navy, is best known for Starship Troopers, but The Moon Is a Harsh Mistress is a more nuanced tale about rebellion, politics, and war. I have a PhD in political science and I worked on the staff of the US Army/USMC Counterinsurgency Center, so I have a soft spot for Moon. Military science fiction and fantasy (SFF) is awash in stories about state-sanctioned military forces duking it out with cool tech, but Moon tells about the rebels. The Loonies launch a shoestring rebellion using a self-aware supercomputer, an electromagnetic catapult, and a DIY ideology summed up by the now-famous acronym TANSTAAFL (there ain’t no such thing as a free lunch). In Moon, as in real life, politics and warfare are inextricably intertwined, which is why I can’t recommend this novel enough. 

When I met Joe Haldeman, I was struck by how such an unassuming, witty person could write such a gritty, visceral novel about war. Haldeman served in Vietnam, and (by his own admission) his combat experience shines through in Forever War. Yes, this novel captures combat in unflinching detail, but I’m a former professor of war, so what I really care about is the intriguing interplay of time, space, and war. As captured so well in the short story version of the novel, “Time Piece,” this novel is less about fighting and dying and more about what war over relativistic distances does to society. I love this novel because it says just as much about those who stay home as it does about those who go into combat.

We need more characters like Paksenarrion Dorthansdotter, the daughter of a sheep farmer who joins a mercenary company to avoid an unwanted marriage. Moon, who served as a Marine in Vietnam, gives us a perfect hero’s tale. Paksenarrion (“Paks” for short) doesn’t set out to garner fame and glory, but she works hard at what she does, and her moral compass is firmly attuned to a sense of justice and truth. Paks captures everything we want in a hero, and Moon’s understanding of infantry, siege, and melee tactics filters through in subtle yet powerful ways, from details like foot soreness on the march to how most sieges end with rebellion within the gates. Sheepfarmer’s Daughter literally has it all. Go read it today. 

Drake served in an armor unit in Southeast Asia in the 1970s, so it’s no coincidence that Hammer’s Slammers, a collection of short stories, revolves around a tank unit. So many military SFF stories focus on knuckle-dragging ground-pounders, so it’s refreshing to see war from a tank turret. Drake has been accused of writing gun porn, but I find a lot of nuance in his writing, especially on combat motivation and small-unit leadership. He was one of the first military SFF authors to write an openly gay character, and women fight right alongside men without the misogynistic or objectifying undertones that sometimes afflict the subgenre. To get a sense for Drake’s writing, “But Loyal to His Own” and “Caught in the Crossfire” are two of my favorite stories.

Mammay, who served multiple tours in Iraq, gives us a completely different kind of military SFF story. Planetside is a murder mystery set in a (space) combat zone, but I love this book because Mammay captures the mannerisms and culture of the military so exquisitely. Every detail is spot on, matching everything I’ve experienced interacting with military officers and enlisted personnel from armed forces around the world. This book is also an absolute page-turner, and it comes together at the end in a way that readers will not expect. And readers need not worry—this murder mystery also has plenty of combat for warfare geeks. For readers that want a window into how the military really works (and not just how it fights), this story is perfect.
