''Hammer's Slammers'' is a series of MilitaryScienceFiction short stories and novellas written by DavidDrake, based loosely off of various historical models and his time in the 11th Armored Cavalry during the UsefulNotes/VietnamWar.

The Slammers are a futuristic mercenary group under the command of Colonel Alois Hammer, who leads the toughest mercs who ever killed for a dollar. According to WordOfGod, partly based on the French Foreign Legion in the 1950s, when that service had a large proportion of former [[UsefulNotes/NaziGermany SS]] in its ranks, but also loosely based on the Vietnam-Era [[http://en.wikipedia.org/wiki/11th_ACR 11th Armored Cavalry regiment]], with fusion-powered hovercraft "panzers" replacing tanks and smaller combat cars replacing M113 cavalry vehicles.

[[folder: The Slammer Stories]]
The series consists of the following works:
* ''Hammer's Slammers'' - A series of short stories describing the core characters of the Slammers and the beginning and end of the tank regiment.
* ''At Any Price'' - Another collection of short stories. The titular story describes the Slammers fighting an unconventional war with aliens who can teleport.
* ''Counting the Cost'' - Based on the suppression of the Nika riots, with a Slammers officer taking the place of Narses (Belisarius' role is played by an officer from another mercenary unit working with the Slammers).
* ''Rolling Hot'' - The Tet Offensive in the Vietnam War retold in the Slammerverse.
* ''The Warrior'' - Another short story collection. The titular story recounts the one-sided rivalry between Slick Des Grieux and Luke Broglie, two Slammers tank aces.
* ''The Sharp End'' - Rewrite of Creator/DashiellHammett's ''Literature/RedHarvest'' on a CrapsackWorld in the Slammerverse, except that the hero is leading one of Colonel Hammer's contract teams.
* ''Paying the Piper'' - The Macedonians against the Aetolian League InSpace! Okay, on a planetary surface. (Happy now?) Available free [[http://baencd.thefifthimperium.com/15-WhentheTideRisesCD/WhentheTideRisesCD/Paying%20the%20Piper/index.htm here]].
Two more novels are set in the same universe but not directly involving the regiment:
* ''Cross the Stars'': a retelling of the Odyssey InSpace with former Slammer Major Donald 'Mad Dog' Slade as the Odysseus character. Colonel Hammer plays Zeus off-screen. Available free [[http://baencd.thefifthimperium.com/15-WhentheTideRisesCD/WhentheTideRisesCD/Cross%20the%20Stars/index.htm here]].
* ''The Voyage'': Re-write of the Jason and the Argonauts myth in the Slammerverse. The nephew of 'Mad Dog' Slade from ''Cross the Stars'' is the viewpoint character. Colonel Hammer again is cast as Zeus, but with only a brief message as an appearance.

[[folder: Repackaged Collections]]
The first five stories were repackaged in a three book set:
* ''The Tank Lords''
* ''Caught in the Crossfire''
* ''The Butcher's Bill''

The entire series (excepting ''Cross the Stars'' and ''The Voyage'') were repackaged (again!) by Nightshade Books (and again by Creator/BaenBooks) as The Complete Hammer's Slammers, in three volumes. This included several novellas not included in the previous collections.

There is also a {{Traveller}}-compatible world guide, available [[http://paizo.com/products/btpy86ef?Hammers-Slammers-Hardcover here]].

!!Provides Examples Of:

* AcePilot: Slick Des Grieux and Luke Broglie from ''The Warrior'' definitely qualify. Broglie is also TheAce, while Des Grieux is [[BloodKnight is not]]. WordOfGod says that their rivalry is based on [[UsefulNotes/TheTrojanWar Hector and Achilles]].
* AgentPeacock: Major Steuben is almost CampGay in regards to his attention to personal appearance and behavior most of the time, but woe betide anyone who crosses him or Alois Hammer.
* AllThereInTheManual:
** Drake provides several essays on the technology and setting of the Slammerverse, most of which tend to get included in the first volumes of most collections.
** ''The Hammers Slammer's Handbook'' by By John Lambshead provides additional background material approved by Drake.
* BeamSpam: One of the staple weapons in the novels is the vehicle-mounted tribarrel, a weapon with three rotating barrels that shoots energy blasts (called "bolts") so fast that the bolts leaving the weapon appear to be a solid line - not individual bolts. The weapons scale up, too - his tanks in the series have both a tribarrel ''and'' a 20cm "main gun" that can literally cook mountainsides with one shot. The tribarrel is based on a cross between the real-life MG42 machine gun and the Gatling gun, both of which have beam-spam-class rates of fire.
* CentralTheme: AnyoneCanDie and WarIsHell, especially the morally murky bits.
* CommLinks: Each soldier is fitted out with a tiny communicator that's implanted in the jawbone. It's activated by clenching the teeth and can even pick up subvocal speech. Handy things.
* TheConscience: Danny Pritchard ends up as Colonel Hammer's conscience, as Hammer's been too hardened by war to recognize when he's gone over the line.
* CycleOfRevenge: Played with in the short story ''Cultural Conflict''. A Slammers soldier [[NiceJobBreakingItHero shoots what he thinks is a dumb animal]]. It isn't. The primitive natives and Slammers begin to skirmish with each other in an escalating cycle of violence, [[spoiler: ending with the decimated Slammers nerve-gassing their nests and wiping out almost all the breeders.]] The remaining natives prepare for one final ZergRush just as the Slammers landing craft arrives.
* ExtendedDisarming: A variant occurs near the end of the story ''At Any Price'', when a mercenary genuinely forgets to remove the small knife he keeps up one sleeve. He actually blushes when reminded that he hasn't disarmed completely.
* FailureIsTheOnlyOption: Mostly in the background, but no one who hires the Slammers ever profits by it. The Slammers achieve their military objectives, but outside of that, everyone involved always loses.
* FakingTheDead: While not stated outright, the character of Johann Vierziger from ''The Sharp End" is strongly hinted to be [[spoiler: Joachim Steuben]] despite taking place over 7 years after his supposed death. He has the same mannerisms and personality, same build and "pretty" appearance, same tastes in both sexual partners and weapons(the description of his custom pistol and holster and [[spoiler: Steuben's]] are identical) same incredible skill at quick draw and marksmanship, and multiple times appears to know more about the unit and Hammer himself than a relatively new recruit would be expected to know. More than one character notes that Vierziger reminds them of what they knew about [[spoiler: Steuben]], with one character even questioning if he might be related.
* FasterThanLightTravel: What kind used is never explained, but it's mentioned to be migrane-inducing.
* FictionalGenevaConventions: In addition to it's escrow duties, the Terran Bonding Authority enforces the Laws of War.
* FightingForAHomeland: The Slammers are from many worlds, but the goal is to eventually have a place of their own.
* HandCannon: Pistols have 2 centimeter bores. This works out to having a 20 millimeter pistol. 20mm and up are ''grenade calibers''. Justified in that they're shooting the "powergun" energy beams, so there's no bullet and significantly less recoil than the barrel diameter would indicate for a typical firearm. Powergun technology is closer to lasers than explosive propellant ballistic technology.
* HollywoodTactics: {{Averted}}. Weapons and tactics are (usually) intelligently used by both sides, to the point that an intelligence operative recommends nuking a rebel stronghold rather than trying to dig them out. The use of chemical weapons is also liberally noted.
* HoverTank: The main equipment for the Slammers is their fusion-powered air-cushion tanks. Each lift fan has its own armored nacelle to protect it from anything that damages another fan; "while a single broken track block would deadline a tracked vehicle, a wrecked fan only made a blower a little more sluggish."
* TheGunslinger: Joachim. Despite his delicate appearance, he's an insanely quick draw and accurate marksman.
* KineticWeaponsAreJustBetter: Averted, mostly. Powerguns (a form of energy beam weapon) are by far the most common high tech weapons. Some armies use railgun rifles instead of powerguns because they have better armor peircing capabilities. However, railguns don't [[{{BFG}} scale up like powerguns do]], are no cheaper since, while their workings are much simpler, their barrels have to be [[BlingBlingBang made from diamond]], and are energy-intensive. [[FrickinLaserBeams Lasers]] are a no-go because they require a 400-lbs. fusion reactor to reach killing power, and explosive bullets are "just as likely to vaporize a leaf as an enemy".
* TheMetricSystemIsHereToStay: Powergun calibers are measured in centimeters, as are most other measurements.
* MindProbe: Played with, particularly the story called " The Interrogation Team". Here the mind probe is semi-painless and takes the form of a directed hallucination. BOTH the interrogator and the person being interrogated are given the drug, and a second interrogator asks questions while the first, in rapport with the victim, experiences his/her memories as the questions are asked. The drug in question is a combination truth serum and hallucinogen, and is described by the first interrogator as akin to a drug high.\\
In this particular story, the interrogated person comes from a heavily defended town, [[spoiler: a "red-pill target"]]. When the authorization [[spoiler: to nuke the town]] is given, the interrogator shares one last vision with the interrogated person - as he envisions [[spoiler: his baby girl's eyeballs melted by the nuclear blast]]. Both the interrogator and the interrogated individual were disconnected from the machine when it happened. DavidDrake does not write ''nice'' stories - perhaps because he WAS a interrogator assigned to the 11th Cavalry during Vietnam.
* ObligatoryWarCrimeScene: Usually by way of [[IDidWhatIHadToDo doing whatever victory required]].
** In one of the stories, Colonel Hammer catches some flak from [[ArmchairMilitary rear-echelon types]] for dealing with an insurgency by having [[HumanShield family members]] of known insurgents ridding on Slammers' vehicles while moving through hostile territory; ambushes of Slammers armor columns dropped, and several attempted ambushes failed because, "somebody noticed their wife or kid on the lead vehicle." Also, gassing a village being used as a heavily fortified base by those insurgents, using gas rather than a nuke only because a gas attack could be done without drawing the attention of reporters. Hammer's actions are about par for the course in the setting.
** Obviously, frequent use of Overkill and WMDs (nuclear and chemical) on civilian populations, too. And a specific story about destruction of a historical shrine due to it being abused as a shield for military forces by one side.
* OhCrap: Happens to one Slammer's unit [[spoiler: who through miscommunication, accidentally end up in the center of an enemy ''firebase''.]]
* PlasmaCannon: Powerguns use precisely arranged copper atoms stored in a plastic matrix. The atoms are pulled down the mirror-smooth barrel of the weapon by electromagnets. The barrels are cooled by liquid nitrogen and air, as most use a rotary assembly. The result is something that performs similar to lasers, rather than the short-range plasma cannon typical of other military [=SciFi=].
* PrivateMilitaryContractors: While Drake mostly uses them to tell stories based on historical events, their mercenary nature plays an important role in their characterization. In the series background, war has become so very expensive that mercenaries are common, and usually the most competent soldiers. The Slammers interact with other mercenary companies and are sometimes shortchanged by their employers. At other times, they play both sides off against each other. The mercenaries and their employers are kept in line by the Terran Bonding Authority, which forces both sides to stick to their agreed contracts. Mercenaries which break their contracts are declared outlaw and hunted down. The Slammers' political maneuvering usually consists of sticking to the letter of the contract while violating the spirit.
* PsychoSidekick: Major Joachim Steuben is in love with Colonel Hammer -- and there's '''nothing''' so awful he wouldn't do it if he feels it'd benefit the colonel. [[spoiler: Including having himself assassinated to give Hammer the chance for a "once and for all" crackdown on the opposition and because he recognizes that his continued existence would be bad for Hammer, and Nieuw Friesland]]
-->"And sometimes a fellow who does one job well can see where his job has to be done, even though a better man has overlooked it. Anyhow, Secretary, there always was one thing you and I could agree on -- lives ''are'' cheap."
* ShootTheDog: Oh, so very much. It is [[WarIsHell war]], after all.
* ShoutOut: In the story "Cultural Conflict", the position initially set up by the Slammers contingent is named Firebase Literature/{{Bolo}}.
* ShurFineGuns: When powerguns work, they work great. However, when they jam, it's usually because the copper-containing plastic matrix they use has melted into the workings so they need to be replaced or are otherwise unavailable. This is particularly a problem for pistol handguns, which can't cool the firing mechanisms fast enough for more than a few shots at a time.
* StandardSciFiArmy: With fusion-powered hovertanks and hovercars armed with directed energy weapons, Hammer's forces are state of the art.
* TankGoodness: Most of the Slammers stories revolve around their panzers and combat cars. Other mercenaries also use blower tanks, although wheeled and tracked vehicles are common for low-end units.
* TheUnfettered: Joachim Steuben, whose Unfetteredness is dedicated to Alois Hammer's use; and Don "Mad Dog" Slade of the ''Hammer's Slammers'' books and ''Cross the Stars''.
* WarfareRegression: Technological developments have altered somewhat the face of combat:
** Powerguns, when tied into a computer, are extremely accurate. This, and the sheer destructive power, range, and speed of the weapon, renders ordinary aircraft obsolete. Artillery can also be interdicted, but remain effective.
** Thanks to "nuclear suppression fields", nuclear weapons are rarely deployed.
** Tanks almost disappear from the battlefield, but make a comeback thanks to practical fusion power and improved weapons.
** [=WMD=]s are shown as rare, but definitely used, particularly chemical weapons.
** However, tactics are almost identical to late 20th-century mobile armored combat, with both panzer (tank) formations and mechanized infantry supported by long-range indirect artillery being the dominant force.
** Recon and intelligence gathering closely resemble that of 21st century warfare, dominated by satellites and stealth recon drones with heavy computerized support for intel processing and communications.
