|Unit Profile (as of 3071)|
|CO||Colonel Gregory Millsey|
Suffering increasing damage from Capellan Confederation raiders during the First Succession War, wealthy merchant princes on Calloway VI formed their own private army in an attempt to defend against them, however, as the Succession Wars continued without end, the merchant cartels found their often-greedy and headstrong troops increasingly difficult to deal with. By the Third Succession War with disagreements mounting, the cartels offered their forces to the LCCC just to get rid of them. With his requests for troops increasingly stymied by the League's Parliament refusal to support his grand "Operation Killing Stroke", Captain-General Thaddeus Marik eagerly accepted the new mercenaries. Formally renaming themselves the Langendorf Lancers, after General Mortimer Langendorf the retired officer hired by Calloway VI’s merchants to form the force, the force became a conventional mercenary command, suffering heavy losses during the truncated and ultimately unsuccessful Killing Stroke in 2950.  
The regular ranked Lancers remained stationed on the League world of Colfax from at least 3025 to 3054.   The only notable event in this period was Janos Marik's daughter Kristen Marik, under the assumed identity of Kristen Markus, joining the Lancers. Wanting to make her own way rather than trade on her name, Kristen started as a Tech before capturing a Lyran Hunchback.  After Janos' death provided Kristen with a large inheritance, a number of Lancers accompanied her to form her own mercenary unit, Kristen's Krushers. 
The Lancers' long period of continuous employment with the League ended in 3058 when the increasingly anti-mercenary Captain-General Thomas Marik transferred their contract to Chancellor Sun-Tzu Liao to bolster the Confederation's efforts in the so-called Chaos March.  Sent to Epsilon Indi to support of pro-Capellan factions trying to take control of the planetary government,  the Lancers were stymied when Duke Benson Abraham hired the Tooth of Ymir to oppose them. Hurt by lack of air cover during their advance into the Chaos March, the Lancers combated this by hiring the mercenary fighter squadron the Night Things to become part of the unit. 
Relatively evenly matched, the uneasy stalemate shattered in 3067 during the opening stages of the Jihad when the increasing distrust of mercenaries and Word of Blake misdirection prompted the Second Com Guard Division to inexplicably attack the Tooth of Ymir, the savaged mercenaries withdrawing to Arc-Royal to rebuild. The Lancers never got a chance to significantly aid the House Liao forces in claiming Epsilon Indi, when only a few months later Word of Blake forces assaulted the Second Division. Ignoring the dying Second Division's pleas for aid, the Lancers desperately staged an assault on the spaceport, boarded two freighters and forced the crews to fly them off-world.  
The Lancers were censured by the MRBC for their seizure of the DropShips after arriving on Galatea, but the Commission eventually conceded that the circumstances had been extraordinary, only inflicting the penalty for defaulting on their contract with the Capellan Confederation. With the Lancers desperate for a new contract and noted for their long history of employment with the League, with elements of the Lyran Alliance launching Operation Überschatten, Tamarind Marshall Jeremy Brett quickly hired them for his counter-attack. Part the forces sent to liberate Gallatin,  the Lancers ran into trouble when their inexperienced AeroSpace Fighter wing broke ranks from the rest of the League task force to stop Lyran fighters from attacking the Lancer's DropShips. While successful in turning them back, the wing's lighter Lightnings and Stingrays paid the price for their mistake, suffering extremely heavy losses against Lyran's heavier Chippewas and Eisensturms. 
Compared to the desperate battle during the approach, the fighting on the ground was fairly routine, with the Lancers assigned to help encircle and isolate the 1st Skye Jaegers in Basingstoke City. Maintaining steady progress at first, stiff resistance resulted in the Lancers closing the gap a day behind schedule, allowing most of the Jaegers to escape and delaying the liberation of Gallatin by weeks. The Lancers moved on with the rest of the League task force to drive the Lyrans from Rexburg, Pingree before arriving on Sheridan where the mercenaries’ supposedly secure landing zones came under intense artillery attack from the mercenary Thor's Hammers just as they were half way through disembarking. While suffering heavy casualties, the Lancers were eventually victorious on Sheridan, and with the Lyran forces increasingly on the back-foot, then proceeded to swiftly capture McAffe. The Lancers then received orders to remain in position, becoming the planet's assigned garrison force.

- - As of 3145 the Lancers were under contract to the Federated Suns and stationed in the Quitacas system, operating at one hundred and ten percent of full strength for a standard regiment.
- The Lancers use a red and white color scheme applied like a knight’s quartered surcoat. The regiment’s insignia is a golden lance over a white L on a black square, all set on a blue field. 
- Born as a defensive formation, the Lancers continue to focus primarily on defense rather than attack, partly to reduce the damage suffered and partly to draw out the length of any combat pay. However this also manifests itself in a great reluctance to attack unless presented with an opportunity too good to pass up. 
- To ease their support requirements, the bulk of the Lancers 'Mechs are medium weight designs with only a few Heavy 'Mechs, though they do boast a number of OmniMechs and advanced Phoenix designs. The Lancers also favor energy weapons over missile and ballistic weaponry for the same reasons. 
- The Lancers rely completely upon their employers or third-parties for transport,  part of the reason for their desperate measures to flee Epsilon Indi.
- Sub-unit "Bowman Banshees" among the defenders of Vakarel around 3025; hint that Langendorf's Lancers might themselves be a sub-unit of the 21st Centauri Lancers by then.
