==Description==
The '''''Ostroc''''' is a [[heavy 'Mech]], weighing in at the lower end of its weight class, originally designed to act as an urban combatant during the [[Age of War]].  The best-known of Ostmann Industries' Ost class of 'Mechs, the ''Ostroc'' debuted in [[Introduction Year::2511]] and proved so successful in this role production continued for approximately 200 years.  Its unique walker/pod profile, later seen in the ''[[Stalker]]'' and ''[[Marauder]]'', combined with a low silhouette similar to the ''[[UrbanMech]]'' makes the ''Ostroc'' difficult to spot in an urban environment.  Fast for its size, well-armored and boasting good medium- and short-range firepower, the ''Ostroc'' was also capable when fighting outside a cityscape, particularly as a heavy scout/raider.<ref name=TRO3039/><ref name=TRO3025>''Technical Readout: 3025'', p. 76</ref>

While a quality 'Mech, the low production capacity of Ostmann Industries made the ''Ostroc'' a rarity; indeed the company licensed their other "Ost" 'Mechs out to [[Kong Interstellar]] just to maintain their rate of production, and the majority of those produced were assigned garrison duties within the [[Terran Hegemony]].  Still, the 'Mech saw action in every major conflict of the [[Star League]], especially towards the end in the [[Amaris Civil War|civil war]] and subsequent [[First Succession War]].  The destruction of Ostmann Industries meant an end to any new ''Ostrocs'', although all sides of the [[Succession Wars (History)|Succession Wars]] continued to field these 'Mechs in combat, particularly the [[Draconis Combine]].  It was because of the small number and wide dispersal of surviving ''Ostrocs'' that the design was largely passed over while others were being updated after the [[Helm Memory Core]] discovery.<ref name=TRO3039/><ref name=TRO3025/><ref name=TRO3050>''Technical Readout: 3050'', p. 122</ref>

A major revitalization of the design took place within the [[Capellan Confederation]] after the [[Clan Invasion]].  Having largely rebuilt their forces after the previous decades' setbacks, the [[Strategios]] wanted to update the ancient 'Mech, but rather than reverse engineering the original they ordered all Capellan 'Mech manufacturers to submit bids for a replacement.  Ceres Metals was the only one to send in a proposal which matched exactly what they wanted and won the contract, completing the first production run in January [[3067]].  Versions of these new ''Ostrocs'' also started showing up in the [[Taurian Concordat]] and [[Circinus Federation]], a result of espionage according to Capellan charges.<ref name=TROPP>''Technical Readout: Project Phoenix'', p. 34</ref>

==Weapons and Equipment==
The ''Ostroc'' carries as its primary weapons two [[Fuersturm-C]] [[large laser]]s in the left and right torsos. These give the ''Ostroc'' good medium to long range damage capabilities. The ''Ostroc''<nowiki>'</nowiki>s secondary weapons are two [[Fuersturm-b]] [[medium laser]]s also mounted in the side torsos and a [[Totschlagen]] SRM-4 launcher in the right torso for close-range combat, with one ton of reloads carried in the center torso.  While the ''Ostroc''<nowiki>'</nowiki>s laser-heavy weapons payload allows it to operate well as a guerrilla fighter since it has limited dependency on supply lines, its short arms are a handicap in close combat, and the shocks of hand-to-hand fighting can easily damage the Fuersturm systems.  The nineteen-ton [[Vlar 300]] [[fusion engine]] propels the ''Ostroc'' to a cruising speed of 86.4 km/h, fast for its size, while fifteen [[heat sinks]] provide adequate heat management.  Although nine tons of armor provide good protection for the 'Mech, very little is used to protect the arms, meaning the loss of one or both in battle is likely.<ref name=TRO3039/><ref name=TRO3025/><ref>''Record Sheets: Phoenix Upgrade'', p. 118</ref>

==Variants==
:'''''Ostroc Mk II''' redirects here.''

*; OSR-2Cb : This upgrade of the 2C was used by the [[SLDF Royal units|SLDF Royals]] starting in [[2729]]. The large lasers are upgraded to [[ER large laser]]s, and the SRM-4 is replaced with a pair of [[Streak SRM-2]]s. Fourteen [[double heat sink]]s keep this 'Mech cool, while [[ferro-fibrous]] armor gives it additional protection.<ref>''Technical Readout: 3075'', p. 169</ref> BV (2.0) = 1,478<ref>''Record Sheets: 3075 Unabridged'', p. 170</ref><ref>''Record Sheets: 3075 Unabridged - Age of War'', p. 24</ref>

*; OSR-2D : Upgraded with [[Star League]] technology, the 2D variant of the ''Ostroc'' extends the 'Mech's maximum range by replacing the large lasers with two ER large lasers. The 2D retains the medium lasers and SRM-4 of the 2C model. To handle the heat burden it is also equipped with double heat sinks. Being a relatively rare design, the ''Ostroc'' had no official field refit kit but the 2D variant was a common upgrade in [[3050]] if the parts could be obtained.<ref name=TRO3050/><ref>''Record Sheets: Phoenix Upgrade'', p. 119: "Note that the record sheet erroneously supplies this design with single heat sinks. They are, in fact, double heat sinks." [http://www.classicbattletech.com/forums/index.php/topic,3308.msg121586.html#msg121586] (dead link)</ref> BV (1.0) = 942;<ref name=BV1 /> BV (2.0) = 1,396<ref>''Record Sheets: 3085 Unabridged — Project Phoenix'', p. 97</ref>

*; OSR-2L : The 2L variant of the ''Ostroc'' introduced in [[2884]] is modified for long range combat. The SRM-4 launcher has been replaced with an [[LRM-5]] launcher, increasing the 'Mech's long-range damage capabilities slightly by sacrificing some of its close range firepower.<ref>''Record Sheets: Phoenix Upgrade'', p. 120</ref> BV (1.0) = 970;<ref name=BV1 /> BV (2.0) = 1,233<ref>''Record Sheets: 3039 Unabridged'', p. 467</ref>

*; OSR-2M : An experimental model produced by Kong Interstellar for the [[Free Worlds League]] in [[2793]], the 2M variant of the ''Ostroc'' focuses on the 'Mech's maneuverability. Five [[jump jet]]s, two in each leg and one in the rear torso, have been added to the design, giving it a maximum jumping distance of one hundred and fifty meters. In order to make this change, the medium lasers and the SRM-4 launcher were removed.  Relatively few of these were built between the League's annexation of [[Connaught]] and the factory's destruction.<ref name=TRO3039/><ref>''Record Sheets: Phoenix Upgrade'', p. 121</ref> BV (1.0) = 1,036;<ref>''Combat Operations'', p. 130</ref> BV (2.0) = 1,239<ref>''Record Sheets: 3039 Unabridged'', p. 468</ref>

*; OSR-3C : The 3C variant looks to improve the long-range direct firepower of the ''Ostroc''.  Introduced in [[2876]], the two medium lasers and the SRM-4 have been removed in order to add a third large laser mounted in the right torso.<ref>''Record Sheets: Phoenix Upgrade'', p. 122</ref> BV (1.0) = 976;<ref name=BV1 /> BV (2.0) = 1,288<ref>''Record Sheets: 3039 Unabridged'', p. 469</ref>

*; OSR-3M : The -3M is a modest upgrade, a bracket fighter created with [[Regulan]] self-sufficiency in mind. Built on [[Wallis]] by  [[Ronin Incorporated]] the variant Heavily drawing on locally sourced ''[[Ostwar]]'' components, a bevy of tried and true extended-range lasers provide the bulk of its firepower, managed via double heat sinks. A [[supercharger]] is the greatest update, giving it a burst of speed when the occasion demands.<ref name=ICR21p6>''IlClan Recognition Guide, vol. 21'', p. 6</ref> Its armor is upgraded with [[light ferro-fibrous]] armor, while it is armed with an ER large lasers and two [[ER medium laser]]s in each torso, with the additional upgrade of the SRM-4 to a [[Streak SRM-4]]. BV (2.0) = 1594<ref name=ICR21p7>''IlClan Recognition Guide 21'', p. 7</ref>

*; OSR-4C : A [[Periphery]] variant of the ''Ostroc'' produced by [[Vandenberg Mechanized Industries]] on [[New Vandenberg]] and also found in the Circinus Federation, the 4C is strikingly similar to the Capellans' 4L variant.  Its armor has been upgraded with nine tons of ferro-fibrous armor, giving it more protection than previous models. Additionally, the SRM-4 launcher has been removed in favor of two [[rocket launcher 10]]s and two [[rocket launcher 15]]s, giving the 'Mech an incredible one-shot damage capability.<ref name=TRJp132f /><ref>''Record Sheets: Phoenix Upgrade'', p. 123</ref> BV (1.0) = 1,089;<ref>''Combat Operations'', p. 138</ref> BV (2.0) = 1,325<ref>''Record Sheets: 3085 Unabridged — Project Phoenix'', p. 98</ref>

*; OSR-4K : This version was introduced by [[House Kurita]] in [[3077]]. A [[heavy-duty gyro]] allows it to stay in the fight longer, making good use of twin [[snub-nose PPC]]s and ER medium lasers. Though it's slightly slower than the standard ''Ostroc'', jump jets allow it to maneuver around the battlefield, striking where it will inflict the most damage. After the [[Jihad]] ended, this model went into factory production.<ref>''Technical Readout: 3085'', p. 246</ref> BV (2.0) = 1,490<ref>''Record Sheets: 3085 Unabridged — Project Phoenix'', p. 99</ref>

*; OSR-4L : A complete redesign of the ''Ostroc'', the 4L carries the best technology the Capellan Confederation has to offer in 3067.  It uses a [[Ceresplex Ostroc Lite Endo Steel|Ceresplex Ostroc Lite]] [[endo steel]] chassis to carry two [[Martell]] ER large lasers and two [[Ceres Arms]] ER medium lasers split between the side torsos.  Five [[HildCo (Jump Jets)|HildCo 13]] jump jets split between the side and center torsos gives it a jumping distance of 180 meters. Finally, the 4L ''Ostroc'' has a Guardian [[ECM suite]] for electronic warfare use and to work with ten and a half tons of [[stealth armor]] which makes it extremely difficult to hit.  While it was originally supposed to use only standard armor, the addition of stealth capabilities makes this variant well suited for operating as a member of Capellan Shadow Lances.  For electronics the ''Ostroc'' carries the [[Ceres Metals Model 686]] and [[Ceres Bullseye]] systems.<ref name=TROPP/><ref>''Record Sheets: Phoenix Upgrade'', p. 124</ref> BV (1.0) = 1,431;<ref>''Combat Operations'', p. 122</ref> BV (2.0) = 1,832<ref>''Record Sheets: 3085 Unabridged — Project Phoenix'', p. 100</ref>

*; OSR-5C : Based on the 4C, this Taurian version introduced in [[3082]] uses an XL Engine, endo steel chassis, and five jump jets. The armament has been replaced with a [[heavy PPC]] and [[light PPC]].<ref>''Technical Readout: 3085'', p. 246</ref> BV (2.0) = 1,788<ref>''Record Sheets: 3085 Unabridged — Project Phoenix'', p. 101</ref>

*; OSR-5W : An upgrade of the 4L, the 5W was produced by [[Kressly Warworks]] for the [[Word of Blake]] starting in [[3070]]. It uses Kallon Unity Weave ferro-fibrous armor, a [[Defiance Industries|Defiance]] [[light engine]], and a [[small cockpit]] to save weight. It uses a [[compact gyro]] to save space. The ER large lasers are replaced with [[Ceres Arms Thrasher]] [[snub-nose PPC]]s, while the ER medium lasers are essentially the same, but [[Diverse Optics]] models instead. Instead of the ECM, the 5W carries an [[improved C3 computer]] in the head.<ref>''Record Sheets: Phoenix Upgrade'', p. 125: "Blakist In-Fighter"</ref> BV (2.0) = 1,655<ref>''Technical Readout: 3085'', p. 247</ref>

*; OSR-6R : Kong Interstellar, a licensee of Ostmann, survived the Succession Wars, and in 3139 returned to its roots and resumed construction with the help of [[Clan Sea Fox]]. This new model opted to upgrade the design to include [[reflective armor]], an [[endo-composite]] skeleton, a larger 360 XL engine that can reach 97.2 km/h, [[CASE II]] and Clan-grade lasers.<ref name=ICR21p6/> Its weapons include two Clan-Spec ER large lasers, two ER medium lasers, and an Inner Sphere Streak SRM-4. BV (2.0) = 2,095<ref name=ICR21p7/>

*; OSR-9C ''Ostroc Mk II'': This [[FrankenMech]] variant of the ''Ostroc'', built with parts from the ''Ostwar'',<ref name=ICR21p6/> swaps the SRM-4 for one [[SRM-2]] launcher in each arm, with one ton of ammunition in the center torso. Half a ton of armor was added to the front torso and legs (adding one point to each leg and side torso, and four to center torso), and four more heat sinks were installed along with three jump jets for a jump capacity of 90 meters. To make room for these components, the engine had to be changed to a Pitban 240, reducing the top speed to 64.8 km/h. (See also Notes below).  BV (2.0) = 1,230<ref name=ICR21p24>''IlClan Recognition Guide 21'', p. 24</ref>

*; ''Ostwar'' Hybrid : Spare parts for the ''Ostroc'' were hard to come by in the [[lostech]] days of the [[Succession Wars era]], which resulted in many ''Ostrocs'' being refitted with parts from an earlier design by the same manufacturer, the ''[[Ostwar]]''. ''Ostroc''s mounting the ''Ostwar''<nowiki>'</nowiki>s arm/hand assembly with paddle-like SRM-4 launchers became such a common sight that many falsely believed this to be the original configuration of the ''Ostroc'' (see Notes below).

===Custom Variants===
*; OSR-2C ''Ostroc'' Michi : Piloted by Michi Noketsuna (see ''Notable Pilots'' below) in the fighting on [[Misery]] against [[Wolf's Dragoons]] in [[3028]], this customized ''Ostroc'' had a top speed of 64 km/h. The reduced engine size allowed the ''Ostroc Michi'' to jump 120 meters and replace the SRM-4 with an [[SRM-6]] launcher. BV (2.0) = 1,321<ref>''Historical Turning Points: Misery'', p. 17</ref>
**This design has a similar flavor to the [[Ostroc Mk II]]

== Design Quirks ==
The ''Ostroc'' has the following [[Design Quirk]]:<ref>''BattleMech Manual'', p. 93: Design Quirk Table - Ostroc Entry</ref>
* [[Narrow/Low Profile]]

==Related BattleMechs==
* ''[[Ostsol]]'' - The ''Ostsol'' was designed and introduced near the end of the ''Ostroc''<nowiki>'</nowiki>s production.  The ''Ostsol'' was designed to be independent of ammunition, allowing the ''Ostsol'' to be a much better deep raider than its primogenitor.
* ''[[Ostwar]]'' - The ''Ostroc'' was designed as an upgraded replacement to the ''Ostwar'' BattleMech.

==Notable Pilots==
*[[Michi Noketsuna]] piloted a red ''Ostroc'' while he was aide to [[Minobu Tetsuhara]], from the training of the [[Ryuken]] [[regiment]]s up until the battle against [[Wolf's Dragoons]] on [[Misery]] in [[3028]]. The 'Mech was destroyed in the fighting on Misery, and Noketsuna was severely injured when he ejected, including the loss of an eye. He later went on to become the [[Bounty Hunter]].

* [[Thomas Reeves]] used an ''Ostroc'' when he served as a Davion mole in the [[Chesterton Reserves]], leaking information to AFFS raiders.{{cn}}

* [[David Levine]] was a well-known MechWarrior-Technician in the [[22nd Avalon Hussars]], who enhanced his blue-and-grey ''Ostroc''<nowiki>'</nowiki>s electronics. His modifications (and success as a raider) drew the attention of [[Hanse Davion]], who held a personal conference with Levine around 3025.<ref name=TRO3025/> Kurita-aligned bounty hunters, however, accidentally killed him and destroyed his 'Mech in a failed kidnapping before the NAIS could attempt to duplicate his innovations.<ref name=TRO3039/>

==Notes==
*The original art going with the ''Ostroc'' when it was first published in ''[[Technical Readout: 3025]]'' and ''[[CityTech]]'' pictured the 'Mech with two flat, paddle-like devices with what looked like four missile ports each for "hands" on both arms instead of the torso-mounted launcher. Although associated with the 'Mech, this image was later clarified to be a common but nevertheless nonstandard variant employing spare parts that were originally meant for another 'Mech, the rare ''[[Ostwar]]'' (which does feature SRM-4 launchers instead of hands); the ''Ostwar'' was a precursor of the ''Ostroc'' and many of their components were interchangeable. (See ''Ostwar'' Hybrid variant above.)<br />It should be noted that the standard ''Ostroc'' mounts its single SRM-4 launcher in the right torso, and has two fully modeled hands. The launcher of this standard version sits upright in the right torso section. This standard configuration with hands and a launcher in the right torso was used for the miniature (see left), depicted in ''[[Technical Readout: 3050]]'' and also used in various artwork such as the [[McCarron's Armored Cavalry (scenario pack)|''McCarron's Armored Cavalry'' scenario pack]] which depicts three ''Ostrocs'' with hands and a shoulder-mounted SRM launcher on the cover.

*The ''Ostroc Mk II'' as canonized in the 2021 ''[[Recognition Guide: ilClan, vol. 21]]'' actually stems from an obscure apocryphal product published 35 years prior that first introduced the 'Mech, the 1986 ''[[TCI Set 7: Marauder and Ostroc Mk II]]'' model kit set from [[Twentieth Century Imports]] (TCI). It contained game stat sheets for the classic MAD-3R ''[[Marauder]]'' and the OSR-9C ''Ostroc Mk II''. Of the design's three [[jump jet]]s, one sits in the center torso while the other two are reportedly mounted in the arms. This fits with the picture and was legal under the earliest design rules from the original ''[[Battledroids]]'' game, but has been illegal since ''[[BattleTech 2nd Edition]]'' (BattleTech rules allow jump jets only in the legs and torso sections). Other than that, the design is legal under current construction rules, including the correct mass to the jump jets (1 ton each). The additional armor was allocated to the front torso (4 points to center torso, 1 to each side torso) and legs (1 point each).In the scenario accompanying the model kit and stat sheet, a [[House Davion]] [[MechWarrior (pilot)|MechWarrior]] recounts how he encountered an ''Ostroc'' that "had been obviously modified" in the defense of Brittany III against a [[House Kurita|Kurita]] invasion. The name of the ''Ostroc Mk II''<nowiki>'</nowiki>s pilot is given as DeMici.
