Editing Castle Brian

First constructed by the [[Terran Hegemony]] in [[2391]], each '''Castle Brian''' (pl.: "Castles Brian") was a massive defensive fortress. They were built on numerous worlds during the Hegemony and [[Star League]] eras.

==History==
Named after [[Director-General]] [[Brian Cameron]], Castles Brian were originally constructed during the time of the [[Terran Hegemony]] as a buffer between it and the [[Draconis Combine]], with the first Castle built on [[Telos IV]].  Within thirty years over a hundred more were built, all along the Hegemony's borders and on important internal worlds.  While a tremendously expensive endeavor no one questioned the Director-General's decision to build them, and events during the [[Age of War]] would prove this effort to be prudent.<ref name=SL256>''The Star League'', p. 25-26</ref><ref name=JHST201>''Jihad Hot Spots: Terra'', p. 201</ref>  In the wake of the [[Reunification War]], with the formation of the [[Star League]], the [[Star League Defense Force]] took control over these structures and more were built in the [[Periphery]] as a means of controlling the rebellious population.<ref>''The Star League'', p. 64</ref><ref name=JHST201/>  Unfortunately when [[First Lord]] [[Richard Cameron]] withdrew the SLDF from the [[Rim Worlds Republic]] in [[2755]], he gave control over these Outpost Castles to his good friend [[Stefan Amaris]].  Amaris' troops occupied these fortifications and studied them so that, with the onset of the [[Amaris Civil War]], Republican forces had a thorough understanding of the structures and how to defeat them.<ref>''The Star League'', p. 80</ref><ref name=JHST201/>  The total number of Castles Brian constructed has never been found, in part thanks to the skill of the Hegemony in building them right under the noses of friends and allies, and as a result many became lost after the end of the war as [[Aleksandr Kerensky]] took the surviving SLDF with him on his [[Operation Exodus|Exodus]].  Soon even the method of their construction became [[lostech]], as did many other wondrous technologies like stasis chambers and [[Storm Inhibitor|weather control satellites]].  The over twenty Castles located on [[Terra]] were eventually taken over and used extensively by [[ComStar]], which were in turn taken over by the [[Word of Blake]].<ref name=JHST201>''Jihad Hot Spots: Terra'', p. 201</ref>

==Description==
The textbook definition of a Castle Brian had a minimum of twenty heavily armed turrets carrying an assortment of direct fire and missile weaponry, fifty smaller turrets and a hundred smaller antipersonnel bunkers.  These were usually the only visible structures of the fortress, which was usually built deep inside a mountain and safe from all but the heaviest [[Nuclear Weapons|nuclear]] or orbital bombardment.  An average of ten levels allowed enough space to store two [[brigade]]s, which could quickly emerge from any of five secret exits.<ref name=SL29>''The Star League'', p. 29, "Castle Brian Fortresses"</ref>  The reality was that no two Castles Brian were alike, and there were several different classifications for these types of fortified structures.  Almost as impressive as the structures themselves were the lengths taken to build them in secret in some of the remotest regions of a planet, including diverting an entire sea to build a Castle on the seabed and flooding the area once more.<ref name=JHST201/>

While often mistakenly believed to have been built to prevent invasion or takeover of a planet, the static fortresses were not meant to protect anything other than themselves and the forces contained within. With the limited resources of the [[Terran Hegemony]] compared to the nations of the other Great Houses, and the later Star League's sheer size preventing blanket defense coverage of most worlds, a Castle Brian was intended to be a hindrance against a blitzkrieg invasion, storing enough weapons, food and men to allow any defenders to hold out and harass the invaders hopefully until reinforcements could arrive.  In effect their very presence acted as a deterrent against invasion for, while an enemy may succeed in capturing a planet, the presence of one or more Castles would prevent them effectively controlling it bar sufficient garrison forces.<ref name=SL29/><ref name=JHST201/>

The correct plural form is Castles Brian<ref>[http://www.classicbattletech.com/forums/index.php/topic,44839.0.html Official CBT forum reply] by [[Herbert A. Beas II]]</ref>; the name stems from the first name of [[Brian Cameron]]<ref>[http://www.classicbattletech.com/forums/index.php/topic,44881.0.html Official CBT forum reply]</ref>.

==Known Castles Brian==
The exact number of Castles Brian in the Inner Sphere and Periphery is unknown, but in [[2423]] The League had already 120 of them. The planet with the biggest number (outside Terra) was [[Lambrecht]], with six of them.<ref>''Star League'' p. 29</ref> 
Earth have at least twenty. On the planets in a radius of thirty light years around Earth, there are Eighty-three.<ref>''Historical Liberation of terra II'' p. 28</ref>

==Castle Brian Classifications==
The SLDF divided the defense structure into several classes as described below.

*Castles
*:The precursor to the modern Castle Brian, Castles were built on important or rebellious worlds, often into the sides of a mountain or beneath meters of concrete.  Castles were stockpiled with weapons and honeycombed with tunnels to allow the garrison to set ambushes.<ref name=JHST201/><ref name=SL132>''The Star League'', p. 132</ref>

*Castles Brian
*:The most famous and awesome example of a castle were the Castles Brian, the first ones creating a chain of fortresses around the Hegemony and making its hostile neighbors think twice before invading.  Full-sized Castles Brian could hold up to two brigades and extended for hundreds of kilometers underground, essentially forming its own city.<ref name=JHST201/><ref name=SL132/>

*Outpost Castles
*:After the Reunification War the SLDF built many Outpost Castles, essentially Castles Brian on a smaller scale, on rebellious worlds in the [[Periphery]].  The [[Rim Worlds Republic]]'s occupation of their Outpost Castles allowed for a thorough understanding of these fortifications and lead to the deaths of many SLDF troopers during the Amaris Civil War.<ref name=JHST201/><ref name=SL132/>

*Port Castles
*:These complex variations on the traditional Castle Brian had a small spaceport built into a highly-protected position, allowing the forces within to more easily be relieved during battle.  No matter how well-defended these spaceports were they still represented a serious vulnerability in the fortress' defenses; consequently few Port Castles were built.<ref name=JHST201/><ref name=SL132/>

*Mini-Castles
*:Mini-Castles were Castles Brian on a much smaller scale, with fewer entrances and the capacity to hold only one [[regiment]].  Often a Castle Brian would have a ring of Mini-Castles built around it to serve as a first line of defense.<ref name=JHST201/><ref name=SL132/>

==Castle Brian Structures==
*[[Anti-Aerospace Bunker]]
*[[Castle Brian Aerospace Hanger]]
*[[Castle Brian Automated Anti-Personnel Turret]]
*[[Castle Brian Gun Emplacement]]
*[[Command and Control Bunker]]
*[[Fortified Brian Wall]]
*[[Large Portal (Mobile Structure)]]
*[[Reinforced Weapons Bunker]]

==Brian Caches==
The term [[Brian Cache]], describing a [[Clan]] equipment store (typically one established during the demobilization process [[Aleksandr Kerensky|Kerensky]] created upon arriving in the [[Pentagon Worlds]]), is derived from the Castle Brian fortresses.
