==History==
===Formation===
The '''Twenty-second Dieron Regulars''' were one of thirty-one regiments of Dieron Regulars to be created by the [[Draconis Combine Mustered Soldiery]] after [[2765]].<ref name="FSWp137"/> The Dieron Regulars expanded by ten regiments during the [[Amaris Civil War]],<ref name="FSWp119">''First Succession War'', p. 119, "House Kurita"</ref> and a further twenty-one regiments were raised between the end of the Civil War and the end of the [[First Succession War]]. Of the latter twenty-one regiments, eight were formed by recruiting [[Star League Defense Force]] personnel and units whilst the remainder - including the Twenty-second - were recruited more conventionally.<ref name="FSWp137"/> With the [[21st Dieron Regulars|Twenty-first]], [[23rd Dieron Regulars|Twenty-third]] and [[Twenty-fourth Dieron Regulars]] all being founded in [[2782]], the Twenty-second was most likely founded in the same year.

=== Third Succession War ===
In late [[3021]] The Twenty-second suffered severe casualties assisting in the defense of the [[Kurita]] world of [[Dromini VI]] against large scale operations by the [[Wolf's Dragoons]] [[mercenary unit]]'s Alpha Regiment in the employ of [[House Steiner]].<ref name=WD-SB1>''Wolf's Dragoons (sourcebook)'', p. 27 </ref>

=== Fourth Succession War ===
The Twenty-second were garrisoned on [[Dyev]] when the second major [[Lyran Commonwealth]] offensive of the [[Fourth Succession War]] began.<ref name="FSWMAv2p75">''NAIS The Fourth Succession War Military Atlas Volume 2'', p. 75, "Dyev"</ref> Dubbed [[Operation HOLDUR]], the offensive was [[Margrave]] [[Jack Sphire]]'s plan to make headway into the [[Dieron Military District]] and saw almost a hundred [[Lyran Commonwealth Armed Forces]] [[regiment]]s attack eight assorted Combine worlds. For [[Archon]] [[Katrina Steiner]] destroying [[DCMS]] 'Mech regiments was as important a goal as seizing territory,<ref name="FSWMAv2p73">''NAIS The Fourth Succession War Military Atlas Volume 2'', p. 73, "Ryde Theater"</ref> and as a result, the [[Seventeenth Donegal Guards]] [[RCT]] was deployed to destroy the Twenty-second. The Regulars were a well-led, seasoned unit, and when the Guards landed they discovered that the Regulars held the two mountain passes that controlled the water supply to the Epsi River Basin, a prosperous region of Dyev. Colonel [[Tommy Gaherty]] made numerous attempts to dislodge the Regulars from their position, but the Guards were unable to pry them out of the mountain passes, and the battle for Dyev became a siege that only ended when the [[Gray Death Legion]] arrived to reinforce the guards in November. Although the Regulars' position remained highly defensible, defending both approaches would have spread the Kuritan forces too thinly, something the Twenty-second's commander knew. The Twenty-second staged a breakout, racing past the Guards to meet with their DropShips in the Basin before abandoning Dyev.<ref name="FSWMAv2p75">''NAIS The Fourth Succession War Military Atlas Volume 2'', p. 75, "Dyev"</ref>

===War of 3039===
The Twenty-second was the garrison regiment on [[Konstance]] when an [[Armed Forces of the Federated Commonwealth]] invasion force struck the planet in July [[3039]]. Konstance was anticipated to be a problem for the [[AFFC]], as the world had four major continents and an atmosphere rich in carbon dioxide. In an attempt to secure the world quickly and prevent the Twenty-second from escaping the AFFC deployed the [[Fourth Crucis Lancers]] and [[Fourth Lyran Regulars]] line regiments and the mercenary unit [[Mobile Fire]] to the attack, which hinged around landings on the continents of Perragea and Epigaus to swiftly seize the major cities and spaceports there. The assault began with problems and proceeded to get steadily worse for the invaders; forced to delay the planned invasion by two weeks because of a [[JumpShip]] problem and issues with coordinating the mix of [[AFFS]], [[LCAF]] and mercenary forces, the invaders found the Konstance system on alert and the defending forces ready for them.<ref name="H:WO3039p31">''Historical: War of 3039'', p. 31, "Konstance (April-July)"</ref>

The main invasion force arrived at the nadir [[jump point]] and swiftly dispatched the local security cordon, while a second, smaller task force arrived at the zenith jump point and captured the DCMS ships there, leaving the Twenty-second isolated on Konstance... and with ''Sho-sho'' [[Tatyana Sobiroff]] determined to avoid a disastrous direct confrontation with the more numerous invading forces in favor of a campaign intended to make life as difficult as possible for the attackers until the Twenty-second could be reinforced. The first battle of the campaign was fought at Ishtalia, the planetary capital city, when a task force led by the Fourth Crucis Lancers spent sixteen minutes defeating the pro-forma defense of the city offered by the defending forces, which consisted of just a [[company]] of [['Mech]]s, a battalion of armor and a battalion of infantry. The limited resistance was a cause for concern on the part of the Fourth, who had anticipated greater resistance, but interning and interrogating the three thousand DCMS personnel captured at Ishtalia failed to reveal any information on the location of the bulk of the Twenty-second or any details of ''Sho-sho'' Sobiroff's plans.<ref name="H:WO3039p31"/>

The Fourth Lyran Regulars and Mobile Fire landed forty kilometers west of Lazarus Bay, the main port city on Epigaus, and moved to secure the city; heavier resistance was encountered at Lazarus Bay than had been met at Ishtalia, with numerous, heavily dug-in conventional DCMS forces holding the city itself while a battalion of 'Mechs from the Twenty-second launched swift flanking attacks against the Fourth. The Lyran Regulars were a light unit themselves and responded with equally swift counter-attacks, turning the flank of the battle into a swirling high-speed battlefield that saw relatively few casualties on either side but an increasing number of mechanical breakdowns due to the tempo of operations. By late May the invaders had secured Lazarus City, but had only captured a few hundred DCMS personnel - the bulk of the defenders having either escaped to the continents of Juranias and Tiburia in transport submarines commandeered from the locals, or simply gone to ground.<ref name="H:WO3039p31"/>

The next few months were marked by relatively few clashes between the Twenty-second and the occupying forces, leading to the AFFC classing the action on Konstance as a police action rather than a campaign, but the Task Force was forced to remain vigilant because of the continuing presence of the Twenty-second on the planet. The Twenty-second launched a series of raids on Epigaus and Perragea soon after a problem with the supply of filter masks left the Fourth Lyran Regulars struggling to conduct operations, whilst [[ISF]] operatives spread rumors to foment discord between the Fourth Lyran Regulars, the mercenaries and the Fourth Crucis Lancers by implying that the Lancers were refusing to share filters with the Lyran forces - despite the truth being that minor differences with the filter equipment made the AFFS and LCAF systems incompatible. With morale dropping among the occupying forces, personality conflicts between the commanding officers of the Lyran Regulars and the Crucis Lancers over who should be commanding the police action continued to cause problems for the invaders.<ref name="H:WO3039p31"/>

With the invasion stalled in the area around Vega due to an ISF strike that decapitated the Lyran command network in the area, the arrival of the [[Third Dieron Regulars]] on Konstance on the 19th of August caused a step-change in the tempo of conflict on the planet. The Third made a daring drop within ten kilometers of Lazarus Bay and swiftly established a defensive line south of the city, seizing on the battle for Konstance as an opportunity to avenge themselves against the LCAF following defeats in the [[Fourth Succession War]]. An attempted counterattack by the Fourth Lyran Regulars saw the Lyran forces driven back, confusion on the battlefield allowing the command company from the Third to rout two battalions of lighter Lyran 'Mechs. The Third then attacked the Lyrans after they retreated to Lazarus Bay, with the Twenty-second emerging from hiding to support the assault. With the exception of the Third Division of Mobile Fire the defending forces were less experienced at fighting in urban terrain than the Dieron Regulars, and the assault into the city was a brutal slugfest fought at short range that inflicted widespread damage on Lazarus Bay. Mobile Fire managed to slow the Third and inflict heavy damage on the attackers, but the mercenary commanding officer, [[Quinten Moore]], was killed in action, leaving Mobile Fire under the command of his executive officer. Realizing that the Lyran position was untenable, the commanding officer of the Lyran Regulars had his forces fall back to their [[DropShip]]s, but rather than making a sub-orbital transfer and relocating the Lyran Regulars and Mobile Fire near the Fourth Crucis Lancers, he instead had his DropShips rejoin their JumpShips, leaving the Lancers behind.<ref name="H:WO3039p75">''Historical: War of 3039'', p. 75, "Konstance (April-July)"</ref>

Despite being heavily outnumbered, the Crucis Lancers were well-fortified and supported - other than lacking infantry - and could have continued to fight, but both sides knew that the battle for Ishtalia would be costly, and neither General Duncan of the Crucis Lancers, ''Sho-sho'' Sobiroff or ''[[Tai-sho]]'' James Kurenai of the Third Dieron Regulars wished to see the same kind of damage inflicted on the planetary capital that had devastated Lazarus Bay. The Dieron Regulars besieged Ishtalia for six weeks rather than trying to force their way into the city, but the siege soon identified that the Dieron Regulars lacked the forces to assault the city directly, whilst the Lancers lacked the forces to break out. When General Duncan received recall orders from the AFFC High Command he made contact with the Regulars, requesting a cease-fire; a meeting arranged two days later between Duncan and Kurenai allowed the two commanders to exchange pleasantries and compliments on the respective performance of both their commands, as well as mutual agreement that the campaign could easily tip either way but would involve considerable further bloodshed, which would be wasteful for all involved. With the DCMS counter-invasion sweeping through Combine space, the long-term outcome was most likely a DCMS victory on Konstance; to prevent further bloodshed, Kurenai offered to allow the Lancers to retreat peacefully with their honor intact. Duncan accepted and the last of the Lancers withdrew from Konstance on the 12th of November, leaving the Third and Twenty-second to rebuild.<ref name="H:WO3039p31"/>

===Clan Invasion===
In [[3050]] the Twenty-second was stationed on [[Dyev]].<ref name=20YU40/>

=== Operation BULLDOG ===
The Twenty-second was stationed on [[McAlister]] when [[Clan Smoke Jaguar]] launched a counterattack in response to the first two waves of [[Operation BULLDOG]].<ref name="TDRp10">''The Dragon Roars'', p. 10, "Unit Summaries"</ref> When the [[Second Jaguar Regulars]] attacked McAlister<ref name="TDRp13">''The Dragon Roars'', p. 13, "Unit Summaries"</ref> they found not only the Fifteenth Dieron Regulars on the planet, but also the [[Fourteenth Alshain Avengers]], [[First Ghost]]<ref name="TDRp10"/> and the elite [[Davion Assault Guards]] [[RCT]] on the planet.<ref name="TDRp11">''The Dragon Roars'', p. 11, "Unit Summaries"</ref> The Second Jaguar Regulars were initially successful, either destroying or damaging a number of supply bases that the [[SLDF]] had established on McAlister to support BULLDOG, and did so in a remarkably short time. The effectiveness with which the second was operating prompted [[Victor Steiner-Davion]] to caution the garrison forces on all five worlds targeted by the Smoke Jaguars that they mustn't be complacent, despite initial assessments that the counterattack was unlikely to disrupt the third wave of BULLDOG. Despite the Second's successes, they were eventually overwhelmed by the superior numbers of the defending forces.<ref name="TDRp36">''The Dragon Roars'', p. 36, "Smoke Jaguar Counterattack"</ref> The Second evidently knew that their assault was a suicide mission, but had been determined to inflict as much damage as possible; deploying two [[Trinary|Trinaries]] of troops in the assault, and was using information obtained from the Watch to target particular supply bases such as Supply Fort Silk; the bases they attacked were as impregnable as the DCMS could make them, combining fixed defenses at sites chosen for their ability to be easily defended, with garrisons of at least two companies of 'Mechs and supporting auxiliary troops at each fort. If the Smoke Jaguar troops hadn't been determined to win and sacrifice themselves in the process, the damage inflicted might've been less, but as it was enough damage was inflicted to prevent the regiments on McAlister deploying in the third wave of BULLDOG.<ref name="TDRp38">''The Dragon Roars'', p. 38-40, "Kamikaze"</ref>

The Twenty-second was deployed to [[Kabah]] in [[3059]] as a part of Operation BULLDOG, securing the planet with minimal losses.<ref name="FM:Up107">''Field Manual: Updates'', p. 107, "Dieron Regulars"</ref> Kabah was a fourth-wave target; by the time the Twenty-second and the supporting [[Nova Cat Lancers (Clan Nova Cat)|Nova Cat Lancers]] landed, the Smoke Jaguar forces in the Inner Sphere were in full retreat; Kabah was one of the worlds where Smoke Jaguar garrison forces lacked transport to escape in, and were left with no way to retreat. The Kabah garrison - the [[7th Garrison (Clan Smoke Jaguar)|Seventh Garrison Cluster]], a part of the Smoke Jaguar [[Psi Galaxy (Clan Smoke Jaguar)|Psi]] [[Galaxy]] - held out for some time in the hopes that Smoke Jaguar forces returning from the counterattack on [[Matamoras]] would be able to evacuate them. The tempo of operations changed when the commanding officer of the Twenty-second was able to convince the Seventh's commanding officer that no help or relief forces were going to arrive; the Smoke Jaguars switched to fighting [[Trials of Possession]], split almost evenly between the Nova Cat Lancers and the Twenty-second, as a means of satisfying their honor.<ref name="TDRp52">''The Dragon Roars'', p. 52, "Wave Four: Clean-Up"</ref>

===Dominion War===
The Twenty-second was still in place on Kabah when the [[Ghost Bear Dominion]] responded to the attacks launched by the [[Alshain Avengers]]; the Twenty-second found themselves fighting a hard-pitched campaign against the [[3rd Bear Guards (Clan Ghost Bear)|Third Bear Guards]] that lasted just two weeks before the Twenty-second was forced to retreat to [[Garstedt]]. The Twenty-second was still on Garstedt in [[3067]], undergoing refits and repairs from the battle for Kabah.<ref name="FM:Up107"/>

===Jihad===
The Twenty-second Dieron Regulars were attacked on [[Nykvarn]] in [[3070]] by [[Clan Diamond Shark]] forces. Battering the Regulars down to a quarter of their nominal strength, the Sharks also inflicted heavy casualties on the [[Twelfth Dieron Regulars]] at the same time. To give them time to rebuild, the High Command reassigned them to [[Schuyler]].<ref name="FR:DCMSp9">''Field Report: DCMS'', p. 9, "Dieron Regulars"</ref> When the [[Bloody Tricentennial]] attacks swept through the [[Inner Sphere]] the Twenty-second was still on Schuyler; terrorists launched an attack on the Twenty-second inside the Twenty-second's garrison within the [[Wakazashi Enterprises]] plant, but the Twenty-second responded quickly and were able to kill the terrorists before the Blakists could sabotage the factory itself.<ref name="FM:3085p37">''Field Manual: 3085'', p. 37, "Blake's Last Gasp"</ref>

=== Dark Age ===
With the establishment of the [[Republic of the Sphere]] and the absorption of much of the Dieron Military District into the Republic, the Dieron Regulars brigade was disbanded, and reformed as the [[New Samarkand Regulars]]. The Twenty-second became the [[Twenty-Second New Samarkand Regulars]].<ref name="FM:3085p41">''Field Manual: 3085'', p. 41, "New Samarkand Regulars"</ref>

==Officers==
In [[3025]], the commanding officer was [[Brigadier General]] [[Tatyana Sobiroff]]; ''Sho-sho'' Sobiroff continued to command the regiment until at least 3039.<ref name=HKDCp133b>''House Kurita (The Draconis Combine)'', p. 133 "MECH UNIT DEPLOYMENT TABLE (as of 3025)"</ref><ref name="H:WO3039p31"/> In [[3050]], ''[[Tai-sa]]'' [[Jason Ohiro]] was the commanding officer of the Twenty-second;<ref name=20YU40>''20 Year Update'' p. 40</ref> Ohiro retired in honor in [[3059]], and was gifted with paired samurai swords by [[Coordinator]] [[Theodore Kurita]]. The swords matched those given to graduates of the Sun Zhang Academy, and were in recognition of Ohiro's efforts in having the Twenty-second embrace Theodore's military philosophies and tactics. Ohiro was succeeded by ''Tai-sa'' [[Bella Solanice]], Ohiro's executive officer, who also received a pair of swords from Theodore at the same time.<ref name=FMDC54>''Field Manual: Draconis Combine'', p. 54, "Unit Profile"</ref>

==Tactics==
=== Third Succession War ===
The command was specialized in scout missions.<ref name=HSDCp144>''House Kurita (The Draconis Combine)'', p. 144</ref>

=== FedCom Civil War ===
Following Theodore Kurita's reforms the Twenty-second changed tactics; reconnaissance missions were shifted to the conventional and aerospace elements of the Twenty-second, while the 'Mech forces within the Twenty-second specialized in learning to use information on potential battlefields to gain tactical advantages, and training to fight in terrain that limited maneuver, such as dense forests, heavily urban environments and mountain ranges.<ref name=FMDC54/>
