Here is a list of 6 Popular Military Science Fiction Books.
Old Man’s War (Old Man’s War, #1) by John Scalzi
From the blurb:
John Perry did two things on his 75th birthday. First he visited his wife’s grave. Then he joined the army.
The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce– and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding.
Dauntless (The Lost Fleet, #1) by Jack Campbell
From the blurb:
The Alliance has been fighting the Syndics for a century–and losing badly. Now its fleet is crippled and stranded in enemy territory. Their only hope is a man who’s emerged from a century-long hibernation to find he has been heroically idealized, beyond belief…
Captain John “Black Jack” Geary’s legendary exploits are known to every schoolchild. Revered for his heroic “last stand” in the early days of the war, he was presumed dead. But a century later, Geary miraculously returns from survival hibernation and reluctantly takes command of the Alliance fleet as it faces annihilation by the Syndics.
Armor by John Steakley
From the blurb:
Felix is an Earth soldier, encased in special body armor designed to withstand Earth’s most implacable enemy-a bioengineered, insectoid alien horde. But Felix is also equipped with internal mechanisms that enable him, and his fellow soldiers, to survive battle situations that would destroy a man’s mind.
This is a remarkable novel of the horror, the courage, and the aftermath of combat–and how the strength of the human spirit can be the greatest armor of all.
Terms of Enlistment (Frontlines, #1) by Marko Kloos
From the blurb:
The year is 2108, and the North American Commonwealth is bursting at the seams. For welfare rats like Andrew Grayson, there are only two ways out of the crime-ridden and filthy welfare tenements, where you’re restricted to two thousand calories of badly flavored soy every day:
You can hope to win the lottery and draw a ticket on a colony ship settling off-world, or you can join the service.
Dreadnaught (The Lost Fleet: Beyond the Frontier, #1) by Jack Campbell
From the blurb:
The Alliance woke Captain John “Black Jack” Geary from cryogenic sleep to take command of the fleet in the century-long conflict against the Syndicate Worlds. Now Fleet Admiral Geary’s victory has earned him the adoration of the people-and the enmity of politicians convinced that a living hero can be a very inconvenient thing.
Geary knows that members of the military high command and the government question his loyalty to the Alliance and fear his staging a coup-so he can’t help but wonder if the newly christened First Fleet is being deliberately sent to the far side of space on a suicide mission.
First to Fight (Starfist, #1) by David Sherman
From the blurb:
Stranded in a hellish alien desert, stripped of their strategic systems, quick reaction force, and supporting arms, and carrying only a day’s water ration, Marine Staff Sergeant Charlie Bass and his seven-man team faced a grim future seventy-five light-years from home. The only thing between his Marines and safety was eighty-five miles of uncharted, waterless terrain and two thousand bloodthirsty savages with state-of-the-art weapons in their hands and murder on their minds.
But the enemy didn’t reckon on the warrior cunning of Marines’ Marine Charlie Bass and the courage of the few good men who would follow him anywhere–even to death. . .
