==Unit Description==
The '''Gray Death Legion''' was the elite mercenary unit of military mastermind [[Grayson Death Carlyle]]. Starting as an offshoot of the [[Trellwan Lancers]], an ad hoc militia unit set up by Carlyle for the defense of [[Trell I]] in [[3024]], the unit eventually grew to regimental size.<ref name=DoHp38>''Day of Heroes'', p. 38</ref> The Legion became famous for the discovery of the [[Helm Memory Core]], which set off a technological renaissance throughout the [[Inner Sphere]], as well as for the most effective use of combined arms tactics, culminating in the development and deployment of [[Gray Death Standard|their]] [[Gray Death Scout|own]] [[battle armor]] models.{{cn}}

The unit was all but destroyed in [[3065]] during the defense of [[Hesperus II]] against [[Free Skye|Skye Rebels]].{{cn}}

==History==
===Founding===
In [[3024]], the planet [[Trellwan]] was garrisoned for the [[Lyran Commonwealth]] by [[Carlyle's Commandos]] when forces working for [[Duke]] [[Hassid Ricol]] of the [[Draconis Combine]] tried to seize the world. The invaders, elements from the [[Oberon Confederation]], shattered the garrison and drove the survivors off planet. [[Grayson Death Carlyle]], the son of the Commandos' commander and the sole remnant of the unit left on Trell I, was hired by the planetary government to build a military force to defend the world against the bandits. Under his skilled command and because of his great knowledge about [[BattleMech]]s the newly formed Trellwan Lancers achieved some astonishing victories and managed to capture several enemy 'Mechs and [[MechWarrior (pilot)|MechWarrior]]s including [[Lori Kalmar]], who Carlyle was able to recruit for his Lancers and who would be his future Executive Officer and wife.

Carlyle also met and befriended [[Renfred Tor]], the unlucky starship captain who had been forced to bring the bandits to Trellwan. With the help of Tor and his [[JumpShip]] Carlyle, after uncovering Ricol's plot, managed to inform the Lyran Commonwealth of the developing situation, forcing the Duke to leave Trell I after the Combine forces were unable to destroy Carlyle and his troops in a final battle. Carlyle took the remains of the Lancers to create a new [[mercenary unit]]: The Gray Death Legion.<ref>This is described fully in the novel ''Decision at Thunder Rift''</ref><ref name=mhb3055p49>''Mercenary's Handbook 3055'', p. 49</ref>

This victory is celebrated on 11 November, the [[Day of Heroes]], when the [[Roll of Honor]] is read and other observations made.<ref>''Mercenary Handbook 3055'', p. 57</ref>

===Verthandi Campaign===
The newly formed Gray Death Legion traveled to [[Galatea]], known as the Mercenary's Star, seeking employment. There they recruited new members, eventually numbering 186 men and women in the Legion. This included seven MechWarriors and two Aerospace pilots in the roster. In the six months on planet, and facing disbandment due to lack of funds, they were forced to accept an offer  by a representative of the [[Verthandi]] Revolutionary Council. The planet had been traded to the [[Draconis Combine]] several years earlier by [[House Steiner]] as part of a treaty obligation and many people were engaged in a guerrilla war against the Combine forces. The Legion was hired to provide training for the rebels, especially in anti-'Mech infantry combat. The initial contract was for 900 hours of training, but no combat engagements. The unit traveled to Verthandi and barely succeeded in running the blockade. The [[DropShip]] ''[[Phobos (Individual Trojan-class DropShip)|Phobos]]'' was severely damaged running the blockade; converted to a steam-powered oceangoing vessel it was actually sailed across the Azure Sea to a safe harbor for repairs. Two of the Legion's members—Captain [[Ilse Martinez]] and [[Davis McCall]]—were primarily responsible for enabling this transformation.

It quickly became clear to Carlyle that the Legion forces would not be able to simply train the rebels, but would need to participate to ensure that the rebellion was successful (which, without the DropShip, was their only chance to leave the planet and evade the cruel House Kurita). Several members of the rebel council were against the Legion's participation, primarily due to concerns of their ability to pay the mercenary unit, but Carlyle succeeded in reassuring them that his forces were committed to fighting the injustices on the planet regardless of their mercenary status.

While the Legion trained the rebel pilots and infantry, Governor-General [[Masayoshi Nagumo]] struggled to locate the mercenary unit. His lord, Duke Hassid Ricol (the same Duke that Carlyle had beaten on Trell I) was pressuring him to crush the rebellion. Through the capture of [[Sue Ellen Klein]], one of the two Gray Death aerospace pilots, Nagumo learned of the location of the rebel stronghold. He arranged a [[Draconis Elite Strike Team]] raid on the complex which resulted in many of the rebels being killed or captured, including rebel leaders and the Legion's technicians. The Legion 'Mechs were on a raid elsewhere when the base was attacked and avoided the ambush relatively unscathed. They then launched a prolonged, guerrilla campaign, increasing their attacks on outposts whenever possible and encouraging outright rebellion by the populace.

The rebellion was concluded successfully when Carlyle led a raid to free [[Lori Kalmar]] who had been captured by the Kuritan forces. The raid freed Kalmar and several of the rebellion's leaders. During the raid, Carlyle was able to secure an enemy ''[[Marauder]]'' which later became strongly associated with him. The Legion forces caught the Combine 'Mechs in a crossfire during the final moments of the rescue and, despite heavy casualties, the rebel forces emerged victorious and the Combine forces abandoned the planet. The Verthandi Campaign was over barely a year after the Legion had run the blockade on October 3025 and beating Nagumo's Trap late August 3026. Finding the cost of holding the world against such determined resistance too high, the Draconis Combine signed a peace agreement in August 23rd 3026, granting Verthandi independence and awarding mining concessions in the planet's southern desert to the Lyran Commonwealth.

===Free Worlds League Service===
After the Verthandi campaign, the unit returned to Galatea to refit.<ref name=mhb3055p51/> Their reputation preceded them. Almost immediately, a representative from Duke Marik and [[Free Worlds League]] signed the Gray Death to their service, for a prolonged series of campaigns against the [[Capellan Confederation]] in late 3026.<ref>''[[Gray Death Legion (scenario pack)|Gray Death Legion]]''(The write-up for Grayson Carlyle notes on p. 9 that the offensive took place (or began) in 3026).</ref>
The Gray Death Legion being hired specifically to conduct aggressive campaigns into [[Capellan Confederation]] space demonstrates that the [[Concord of Kapteyn]], which had been signed for over five years, did not cause much of a détente between Houses Marik and Liao after all. The unit was hired to keep the Confederation off-balance, and for over one standard year enacted a series of hit-and-run strikes against communication centers, fleet depots, 'Mech assembly plants, mines and industrial worlds.<ref>The ''[[Gray Death Legion (scenario pack)|Gray Death Legion]]'' pack notes (in the unit history section on p. 7)</ref>

The unit performed admirably during several operations and garnered a good reputation. Following their successful [[Battle of Sirius (3028)|Liberation of Sirius V]] in early [[3028]], the unit planned to return to its landholding of [[Helm]]. One of the terms of the contract with House Marik stipulated that the Gray Death Legion would be granted an extensive fief on the planet. Unfortunately, unbeknownst to either the Gray Death Legion or [[Janos Marik]], that fief held an ancient [[Star League]] weapons cache including a field library.<ref name=DoHp6>''Day of Heroes'', p. 6</ref>

A rogue [[ComStar]] [[Precentor]] named [[Emilio Rachan]] created a byzantine plot involving a [[Free Worlds League]] noble whereby the Legion was framed for the [[Tiantan massacre]], the destruction of the domed city of Tiantan on Sirius V which killed between 12 and 17 million people. The unit was kept uninformed about the atrocities committed following their departure, yet, sensing something amiss and despite orders from the Duke to go to [[Marik]], Carlyle instead led the Legion back to their landhold on Helm. The general outrage produced by repeated airings of holovids of the massacre resulted in the Legion being declared outlaws.<ref name=DoHp6>''Day of Heroes'', p. 6</ref>

====Discovery of the Helm Memory Core====
While the unit was off-world, Free Worlds League militia units had invaded [[Helm]], among them the [[12th Atrean Dragoons|Twelfth Atrean Dragoons]], believing the story of the atrocity at Sirius V. They killed or captured many of the unit's dependents who had remained. When the Legion landed on March 24th, they found their stronghold [[Durandel]] devastated and found themselves under attack by a League Unit, House Marik's 5th Light Battlemech Guards of the Hammerfall Company.<ref>''[[Gray Death Legion (scenario pack)|Gray Death Legion]]'' scenario pack established that the first battle with the Hammerstrike Company in the ruins of Durandel, immediately after landing on Helm, occurred on 24th March. ("Thirst for Vengeance" scenario epigraph, p. 33 top header)</ref> They eventually learned about the possible existence of a [[Star League]] cache on the planet; as it turned out, none other than Duke Hassid Ricol had come all the way from the Draconis Combine following the same leads as Rachan and his Marik conspirators. Carlyle struck a deal with Ricol, managed to find the cache, and realized the library to be the true target of Rachan's machinations. By 1st of April, besieged and attacked by the pursuing three Regiments of Marik forces, Ricol and the Gray Death Legion narrowly managed to secure a copy of the [[Helm Memory Core]] and a small fraction of the cache's extensive treasures before the entire facility self-destructed. <ref>''[[Gray Death Legion (scenario pack)|Gray Death Legion]]''
The final battles and the recovery of the memory core occurred on 1 April 3028 ("Betrayal at Helm" scenarios, p. 35 top header).</ref>

Carlyle subsequently felt that the memory core was too valuable for humanity at large, and too big a blood price had been paid for it, to keep it for himself. He made sure that many copies were created and disseminated throughout the entire [[Inner Sphere]], an action that made him and his unit extremely famous and popular.<ref name=mhb3055p51>''Mercenary's Handbook 3055'', p. 51</ref>

===Fourth Succession War===
The Legion were actively involved in [[Operation GÖTTERDÄMMERUNG]], the major Lyran Commonwealth offensive of the [[Fourth Succession War]]. During the opening wave of attacks in August [[3028]] the Legion captured [[Shionoha]], where a light recon 'Mech lance had scratched out a victory over the militia garrison. Then to [[Aubisson]] in the followup attacks, a more important target sixteen lightyears in from the frontier.<ref>Battletech Legends - All Wet page 24 (short story)</ref> This time with a Battalion of 36 mechs. Aubisson in particular proved the incredible tactical cunning of Grayson: instead of attacking the capital, the lone 'Mech Battalion of the Legion attacked ''PowerOne'', the planet's main fusion plant, located in an island. With Khaled leading a frontal attack, Grayson led a lance underwater by the opposite side. Despite having to haul his ''Marauder'' over a cliff, the attack caught the defenders by surprise and surrended quickly, with the planet following soon.<ref name="NAIS4SWp44">''NAIS The Fourth Succession War Military Atlas Volume 1'', p. 45: "Operation GÖTTERDÄMMERUNG"</ref><ref>''BattleTech Legends'', pp. 24–31</ref>

The Legion was subsequently hired by a faction within the Lyran Commonwealth in [[3029]] and tasked with several raids into Kurita space as part of House Steiner's [[Orestes]] campaign, including savage fights on [[Caldrea]] and [[Otho]], a delaying action on [[Trolloc Prime]] and leading the assault on [[Baldur]]. In [[3030]], the unit allowed Steiner forces to disengage on [[Lothan]], disrupted an invasion fleet at [[Nox]], and captured a vast store of supplies and equipment on [[Darius]], growing to regimental size.<ref>''Gray Death Legion'', pp. 7–8</ref><ref name=mhb3055p51/>

Because of his attitude and the experience with Marik, Carlyle would subsequently not consider contracts from Houses Kurita, Marik or Liao.<ref>''The Price of Duty'', p. 57</ref>

===War of 3039===
====Altais====
The LCAF had special interest in [[Altais]], as a staging point for further invasion and also to block any counterstrikes from the DCMS. The task force invading the planet consisted of the [[Eighth Donegal Guards]] supported by two mercenary commands, the First [[Dragonslayers]] and the Gray Death Legion. Official reports suggested that the planet should be undefended despite rumors of two unknown formations on planet. The [[1st Ghost|First Ghost]] were tasked with the defense of vital spaceports. That was also the target of the Gray Death Legion who landed as second unit of the task force on the world. The mercenaries staged simultaneous strikes at the two spaceports, Willas and New Ross.<ref name=CM>''Combat Manual: Mercenaries'', p. 42</ref> The first combat drops were uncontested but the second were difficult for the Steiner forces. The First Ghost launched three assaults on that position in short order but were always beaten. The other half of the mercenaries traveled over 150 km from their landing point to support their beleaguered comrades. Unexpected by the First, the flanking raids were devastating. The Legion pursued the Ghost forces and barely three companies could retreat off planet.<ref>''Historical: War of 3039'', pp. 29–31</ref><ref name=ER52>''Era Report: 3052'', p. 41</ref>

After the War of 3039 the Legion had a long-term garrison contract with the Federated Commonwealth and were stationed on [[Sudeten]], with occasional pirate hunting missions.<ref name=CM/>

===Clan Invasion===
When the [[Clans]] appeared in [[3050]] and rolled through any and all opposition, the Gray Death Legion were one of the units to fight them with some success. The Legion suffered [[Battle of Sudeten (3050)|heavy defeats]] on [[Sudeten]] where they had been stationed prior to the [[Clan Invasion|Invasion]], losing that world to [[Clan Jade Falcon]], but on [[Pandora]], despite having to disobey orders to succeed, managed to defeat the Clans for the first time ever. On Pandora they used modified battle armor suits and other upgraded technology.<ref name=ER52/> With severe damage to the Legion and having acquired substantial salvage of [[lostech]], or, as the Legion call it "Foundtech," they became very famous as one of the premier mercenary units in the Inner Sphere.<ref>''Mercenary's Handbook 3055'', p. 52</ref>

===First Skye Secession===
In [[3056]] the Legion was gifted with the world of [[Glengarry]] in a political move by [[Victor Steiner-Davion]], but they immediately had to defend the world against Skye Separatists who did not want them there. The defensive guerrilla campaign was led by [[Alexander Carlyle]], the son of Grayson and Lori Kalmar Carlyle. The younger Carlyle held out until the unit could return home to take care of things, though the forces on the planet suffered heavy losses and Alexander lost his best friend, Davis Clay, who was the son of one of the original members of the Legion.

===Second Skye Secession===
The third most senior member of the Legion, Davis McCall, received word from his estranged family that atrocities were occurring on his homeworld of [[Caledonia]], three jumps from Glengarry, and he went, with Alexander Carlyle, to investigate in the event that the Legion were deployed there as per rumors that were heard. This was all part of an elaborate plot by Marshal Brandal Gareth to discredit and disband or destroy the Legion as part of his plot to carve an empire for himself centered on Hesperus in the Skye March. After a failed assassination attempt by Gareth on Grayson and Lori, elements of the Legion deployed to Caledonia and were ordered by the government to fire on civilians, leaving them with the option of either causing atrocities and breaking interstellar law, or refusing to obey and breaking their contract with the Federated Commonwealth. With the previous intelligence gathered by McCall and Alexander Carlyle, Grayson sided with the rebels and, even though outnumbered two-to-one by elements of the [[3rd Davion Guards|Third Davion Guards]], defeated them in combat. However, a traitor planted within the unit by Gareth ambushed Grayson Carlyle and crippled him, including damage to his inner ear that would prevent him from ever piloting a BattleMech again.

Meanwhile, Gareth moved against Glengarry in an attempt to destroy the Legion in response to their breaking of the contract with the Federated Commonwealth. [[Lori Kalmar-Carlyle]] managed to hold the attacking force at bay until the rest of the Legion arrived from Caledonia and Gareth retreated off-world, leaving the battle to be fought in the courts. The senior staff of the unit were summoned to the capital world of [[Tharkad]] just as [[Katherine Steiner-Davion]] announced the separation of the [[Lyran Alliance]] from the rest of the [[Federated Commonwealth]] and the Legion were found guilty of breaking their contract, though Grayson Carlyle resigned from the unit in order to absolve them of blame, citing his personal choice as the deciding factor in the crime. From there, he left the unit and went to work with Gareth on Hesperus, though he was secretly an agent for the Lyran Alliance, attempting to ascertain what Brandal Gareth had planned. He agreed to side the Legion with Gareth in whatever plot was being hatched, pretending to not have any loyalty with the Steiners after their handling of his court martial. Gareth then declared an independent state called the [[Free Star Republic]], having gotten the young, impressionable [[Daniel Brewer]], CEO of [[Defiance Industries]] to support his grab for power. The Legion were deployed to support Gareth on Hesperus, but instead turned around and took over the BattleMech factories for [[House Steiner]]. Defending them against Gareth's forces while Grayson Carlyle led a daring commando raid to capture a JumpShip and go for help from other House Steiner forces. After these actions, both Grayson and Lori were awarded the McKennsy Hammer by a grateful [[Katherine Steiner-Davion]] and again awarded Glengarry as a home.

===Destruction===
In [[3065]], they received orders to reinforce the defenders of [[Hesperus II]] against possible invaders, whether they might be [[Victor Steiner-Davion]]'s forces or [[Skye]] rebels (at this time, the Gray Death Legion consisted of two 'Mech battalions, one tank battalion, one battle armor battalion and one aerospace [[Wing (Military Unit)|wing]]). There, they fought alongside the [[Fifteenth Lyran Guards]] and [[36th Lyran Guards|Thirty-sixth Lyran Guards]] against the [[Fourth Skye Rangers]], [[Seventeenth Skye Rangers]], and [[Twenty-second Skye Rangers]]. They were able to defend [[Defiance Industries]]. The victory of the Lyran forces essentially spelled the end for the rebellion, though it came at a heavy cost to the Legion. They ceased to exist as a combat command. What remained of the unit was folded into the [[Defiance Self-Protection Force|Defiance Security Forces]], as the highest-ranking surviving officer [[Daniel Brewer]] was also chief executive of Defiance Industries. The Defiance Security Forces were annihilated during the [[Jihad]].

Alexander Carlyle, who had been serving in the [[LAAF]] in the [[Second Royal Guards]] on [[Tharkad]], had intended to rebuild the Legion, but was prevented by several factors. First, he was not allowed to leave his unit in midst of the [[FedCom Civil War]]. In the aftermath of the war, his family was stripped of its holdings on Glengarry, and the [[Mercenary Review Board|Mercenary Review and Bonding Commission]] indicated that because of the Legion's spotty track record with turning on their employers, they could not be appropriately graded.<ref name="TR3058Upgradep22">''Technical Readout: 3058 Upgrade'', p. 22</ref> Still an LAAF officer, Alexander Carlyle was on Tharkad when it was bombed from orbit at the onset of the Jihad.

Some of the surviving support staff would return to Glengarry to form [[Gray Death Technologies]], to continue to manufacture and market the Legion's unique battle armor, the [[Gray Death Standard]] and the [[Gray Death Scout]].<ref name="TR3058Upgradep22"/> Gray Death Technologies would later be bought out and absorbed into Defiance Industries in the post-Jihad era.<ref name="xtros15">''Experimental Technical Readout: Steiner'', p. 15</ref>

===Rebirth===
In 3151, after their former LCAF unit, the [[26th Arcturan Guards|Twenty-sixth Guards]], defected to the [[Tamar Pact]], siblings [[Ronan Carlyle]] and [[Isobel Carlyle]] formed a mercenary company on [[Garrison]] using salvaged equipment and staffed with other former LCAF members, Twenty-sixth Guards loyalists who had been cashiered from the LCAF. The new unit resurrected the Gray Death Legion name and logo used by their great-grandfather [[Grayson Death Carlyle]], their great-grandmother [[Lori Kalmar-Carlyle]], and their grandfather [[Alexander Carlyle]] before he joined the LAAF. The reborn Legion won its first battle easily, containing a defecting Lyran recon company, targeting their equipment and stopping them without suffering or causing losses, taking a lot of salvage from the surrendered company. After the battle, an officer of the reborn Tamar Pact informed the Carlyles about the imminent expulsion of the company, suggesting the Legion to recruit them and offering them a contract for the Pact.<ref>''The Price of Duty''</ref>

===Working for the Pact===
The Legion commanders accepted the advice, ultimately growing to about two companies, and accepting work for the Tamar Pact. Their first post was on the planet [[Crimond]], recently absorbed by the Pact, in February [[3152]]. There, the unit divided in two: Ronan took the main body to help police forces to crush a terrorist group, while Isobel took the remainder, which she called ''[[Carlyle's Commandos]]'' to another continent, to secure an old Star League base. Both groups completed the tasks assigned without casualties and in no time, proving their high quality and adaptability, even bringing more recruits to the Legion.<ref>''Mercenary's Honor''</ref>

Sometime later, the Legion absorbed the remnants of another mercenary unit shattered on planet, [[Fitzroy's Fusiliers]]. That made the Legion a short battalion, with two full companies and the bones of a third. After finishing their work on Crimond, their employers send to garrison [[Pandora]] at least for six months.<ref>''Decision at Pandora'', chs. 2–3</ref>

However, the garrison contract wasn't uneventful: Barely days after the Legion settled on Pandora, the planetary governor launched a coup to attempt to secede from the Tamar Pact, and as the Legion had refused to be bribed, they blamed them for a terrorist attack and attempted to destroy the Legion. 
However, the Legion was warned and they managed to easily crush a rebel company of 'Mechs, and later launch a counterattack which defeated the secessionists, returning the planet to the Pact's control. The salvage taken allowed the Legion to become a full battalion, at least on paper.<ref>''Decision at Pandora'', chs. 6–16</ref>

Eventually, after finishing the six months garrison contract with the Pact, the Legion didn't renovate it, and, in 7 June 3152, they were on the Draconis Combine world of [[Gram]], where they made a short stop, while going for their next contract.<ref>''A Lesson Learned''</ref>

===3028 (Glengarry)===
After the debacle at Helm, Col. Carlyle negotiated a new landhold. In exchange for past services to the Lyran Commonwealth, the Legion was offered one on Glengarry. Without even being able to recover from their losses, they were offered a contract for counter raiding into Draconis Combine space. 11.5 million C-bills plus expenses to raid Imbros III. Grayson accepted with the proviso of only taking volunteers and leaving both their Unions to support their dependants, most of whom had suffered loss of friends and family on Helm.

==Uniforms and Color Schemes==

====Field Uniform====
The field uniform is a dark gray, loose-fitting tunic and trousers, featuring several large pockets. Officers wear their rank and unit insignia on the uniforms epaulettes, with rank insignia closest to the point of the shoulder. Noncommissioned officers and enlisted men wear their insignia on the upper sleeves of their tunics, with their unit crest above their insignia.

====Dress Uniform====
A more formal version of the standard field uniform, the Legion dress uniform replaces to loose-fitting, many pocketed fatigues with tailored pants and a jacket worn over a close-fitting white shirt. The trousers, a lighter shade of grey than the vintage jacket, are trimmed with red stripes running down the outside of each leg. A dark gray half-cape with red silk completes the uniform dress occasions. Rank and unit crest are displayed in the same manner as on the field uniform.

Retired officers add a white shoulder and collar flashes to the Legion's dark gray and red dress uniform.<ref>''Mercenary Handbook'', p. 57: Gray Death Legion</ref>

====Color Scheme====
The Gray Death Legion employs a gray-on-gray camo pattern. A colored circle on the right leg tells what battalion they belong to. Yellow for first, Green for second, Blue for third and Red for Headquarters and Command.<ref>''Field Manual: Mercenaries'', p. 56</ref>

==Other Appearances==
{{ApocryphalContentStart}}
* The Gray Death Legion appear in the ''[[MechWarrior IV: Mercenaries]]'' PC game as potential sponsors. Due to the timeline the game is set in, the Legion is described as rebuilding after their decimation on Hesperus II (instead of being destroyed). This was not considered [[canon]] by the writers of the BattleTech timeline. The Legion was also portrayed as being very loyal to House Steiner, a sentiment which is echoed in the BattleTech novel ''[[Tactics of Duty]]''. Units sponsored by the Gray Death gain earlier access to Lostech weapons.
