A

 * Aerospace Fighter : This is a form of trans-atmospheric combat vehicle, which can fly in a planet's atmosphere on in space. It powered by fusion power planet can achieve great speeds. Like all combat vehicles with fusion reactors they, have can be equipped with array of weapons and need heatsinks to regulate the heat generated by these powerful systems.


 * Age of War : This was designation for early time period (sub-era of Star League Era) where mass colonization and formation of early interstellar nations formed and fell with rapid uncheck warfare which razed many wars. During this time period, BattleMechs were introduced changing warfare. This unrest time period would end when the Terran Hegemony mediated treaty to lessen the harshness of the war and eventually lead to formation of the massive interstellar nation known as the Star League.


 * Air Mech Mode : This is a state where a Land-Air Mech is reconfigures/transforms/changes into a hybrid of Aerospace fighter & still retains arms and legs of a BattleMech. While not fastest form, of the three configurations it can changed into, it allow maximum movement on ground and above it. Giving it unmatched maneuverability and speed.

B

 * Battalion : A medium size formation found in Battletech, this is usually consists of 3 companies worth of combat units (BattleMechs/Combat Vehicles) where, infantry and other traditional troops number may vary. Typically this formation is commanded by an officer rank as Major, usually requires three Union-Class Dropships to transports (if combat vehicles/Mechs are used.)


 * BattleMech : This is a Robotic Combat Vehicle, which is typically piloted by a pilot known as a MechWarrior. Considered to be ultimate combat machine, it can have range forms from human like two legged machine, strange three legs, or have four legs not unlike a horse/dog. It comes with array of weaponry and typically is powered by Fusion Reactor. They can weigh from 20 tons to 200 tons. This is primary unit used in the BattleTech Universe.


 * BattleTech : Name of the Tabletop franchise started in 1984. Originally of a box set, this has spun array of various games, fiction and more. BattleTech can also refer to (in game) as technology of Battle.


 * Battle Armor : This is a form of personal infantry Armor that is mechanically enhanced with added strength, protection, and firepower so to better counter large threats such as BattleMechs. Originally created by the Star League for it's Special Operations teams, the concept would be better refined by descents of the SLDF, the Clans. Later after the Clan invasion in 3049, new Battle Armor is created by the Inner Sphere powers.

 * Clans : They are a descents of the Star League Defense Force (SLDF) which left the Inner Sphere in wake of Civil War that essentially destroyed the Star League. These descendants became a Warrior Culture, which was shaped by the son of the last commander of the SLDF.

 * Clan Tech : This a technology developed by the Clans of Kerensky during the 28th Century to 31st. Technological improvement grow vastly more with the Clans verse the Inner Sphere which lost considerable technology during the Succession Wars Era. Typically Clan Tech is sought out due to the increase damage and weight savings of compariable weapons used by the Inner Sphere and technology developed by the Star League. Only the Clans were able to produce this technology. It would not be further available to Inner Sphere powers by the 32nd Century.


 * ComStar : This is was organization that was originally created by the Star League Counsel after the Star League Civil War as caretakers of the massive interstellar communication arrays known as HyperPulse Generators. The HPG Network allows communications between the stars. As centuries past, in effort to sustain itself from unslaught of the violent Succession Wars, ComStar turned to a religious dogma in order to prevent secrets of its technology to leak out and provide integity to the organization with hidden goal restoring the Star League under it's direct control. The organization began in 2785 and ended 3150 after its bankruptcy when a Hyperpulse Generator Network was sabotaged causing communication blackout through out the Inner Sphere, better known as Gray Monday. ComStar's slow demised over few decades would ushering new age of conflict known as the the Dark Age.


 * Combat Vehicle : Combat Vehicles are more traditional ground vehicles used for combat in the Battletech universe. They evolved from normal combat vehicles used since the 20th Century on Earth. Like BattleMechs, they can equipped with array weapons and armor. They were sidelined as leading combat vehicle when BattleMechs were invented, however they continue to support and be used in battle. These are family vehicles broken down to sub types based on their propulsion system. A Combat Vehicle must be under certain weight class for Combat types.


 * Circinus Federation : In canon is a Periphery nation which is situated on "western" part of the Inner Sphere's borders of the Lyran Commonwealth and Free Worlds League.

By 3067, the FedCom Civil War was over, with both nation states with new leaders and FedCom dissolved.


 * Ferro Fibrous : Ferro Fibrous (Abbreviated as FF Armor) is a type combat armor used on various type of ground and aerospace vehicles. While not stronger than Standard Armor, it is lighter. This allows for additional heavier equipment to placed in a unit which has it.

Typically these machines are powered by Internal Combustion Engines (ICE) and usually are fitted with industrial grade armor which isn't as strong as standard armor found on BattleMechs. However, they can be armed in desperate situations. Mechs modified in this fashion are designated with MOD (if their formerly civilian models), signifying it's a armed IndustrialMech. However, planetary militias do field what term as purpose built MilitiaMechs, which are low-tech combat mechs, which use heavy industrial armor and added military grade equipment which are more survivable than IndustrialMechs retrofitted with weapons.


 * Inner Sphere : This is given name of the BattleTech universe's setting in side the Milkyway Galaxy. Not consisting of entire galaxy, however, a massive part of it.

J

 * JumpShip : A form of Starship used by Human civilization in the BattleTech Universe. The ship final component of a 2 segment transportation system. They can not move quickly in normal space, require stay in area without any gravitational influences. These ships use massive amount power which they need to leap between measurement of distance to reach their destination instantly. However, they must use massive solar sails to recharge their batteries. In some cases special batteries can be added to allow a double jump. JumpShips since destructive Era of the Succession Wars, JumpShips are fairly rare, near taboo to destroy due to loss of means building them in large numbers.

OmniMechs themselves, have fix amount of weight of Podded equipment they can carry based on their size and allotted room. Equipment that cannot bemoved, that is permenant to the OmniMech is usually referred to fixed equipment. OmniMechs are knowns to require more maintenance than normal BattleMechs (this was game mechanic to balance out differences between OmniMechs and standard BattleMechs.)

 * Star League : This largest interstellar nation created by mankind. Fusion of alliances between the major Inner Sphere nations lead by Terran Hegemony. The nation waged war against minor nations outside the Inner Sphere, known as the Periphery States. The war was used to fuse the early shaky alliance of Inner Sphere nations into more fused nation. However, after successful conquest, centuries would past and discontent would rise among the League's member states. Betrayal of a leader of the Periphery State, kill the Star Lord of the League, taking throne in a coupe for himself.

 * Succession War, First : This was first war of the Succession War era, where all five remaining Star League member state, at the peak of the their military build up and technology unleash total warfare against each other. This would the conflict where brutal strikes each other left millions dead from worlds being annihilated from devastating planetary bombardments and use of nuclear weapons. By the end of the conflict a considerable amount of factories are destroyed and technology levels of all the combatants begins to slide downwards, with countless millions dead on all side, what was former Terran Hegemony lay in ruins as mass land grab among other moves.


 * Succession War, Second : Mere decades after the First Succession War, the Second would begin. The remaining forces with enough military strength and consternation Star League level technology is thrown in to final throws of battle for domination in effort try make gains before the mighty nation is expended. This is era where Star League technology levels would go extinct, where last of the Inner Sphere's WarShips would be lost in efforts hold one another off from tipping tables to the other winning a conflict before troops make their land fall.


 * Succession War, Third : This is war which lasts centuries, however, it is time period where Inner Sphere's Succession States as they would become to be known as would only periodically muster enough BattleMechs and troops to casual raids for resources and rarely launch massive invasion troops mustering beyond a Regiment (105 BattleMechs).


 * Succession War, Fourth : The final Succession War in name and the shortest one, with war being fought from 3028 to 3030. This would be war where Federated Suns and Lyran Commonwealth would commit to alliance to merge their states into nation not seen since the fall of the Star league. Where they would Federated Suns conduct massive invasion into the Capellan Confederation and Lyran Commonwealth would move towards Terra cutting into the Draconis Combine and Free Worlds League where they would secure the borders between the two nations. The three other Succession States having formed an written document forming alliance known as the Kapteyn Accords, failed to work together to prevent Federated Commonwealth from forming, resulting Capellan Confederation being cut in half, leaving the Free Worlds League in chaos.


 * Squadron : Typically as Squadron is formation of 6 aerospace or conventional fighters or even VTOLs combat units.

These guides, are published names are traditionally use game year or Era its representing. Example "Technical Readout: 3025" or "Technical Readout: Succession Wars". Some specialty publications of this kind do not use year/era reference as part of their name, but by what focus of the publication. Such as "Technical Readout: Vehicle Annex" which specialized on civilian type vehicles or secondary vehicles on frontline combat units.


 * Terra Alliance : The Terran Alliance was 1st interstellar nation formed by Human kind. Center on Terra, the democracy lead nation would usher age discovery with invention of the K-F Jump Drive, creating countless worlds across space. However, as humans colonized space, old political unrest continued on Terra, created divisions among it's political standings, eventually leading to isolationist taking over the leadership of the Alliance and cutting off most it's colonies encircling Terra. As Terra turned on itself ending in a Civil War, it's own military would turn it's guns against the unstable democracy in a coupe lead by Admiral James McKenna. This coupe would form a new nation with limited elections called the Terra Hegemony.


 * Terra : This is name used for Earth in the BattleTech universe. It is center of all human culture and once the seat of power for Terran Hegemony, later the Star League, ComStar, and Republic of the Sphere.

In later eras, Terra would be again the capital of the Republic of the Sphere and ilClan's version of the Star League.


 * Terra Hegemony : This was the 2nd interstellar nation to form centered on around world of Terra. Lead by the Director-General, the nation was quasi-Monarch (Director-General) and mix regional governors and elected Hegemony Congress.

 * This is type of Combat Vehicle which is basically a type Helicopter, however vertical Launch able can Aircraft be also designated under this type of designation.

W

 * WarShip : This is a rare type of JumpShip, which can move between planets unlike normal JumpShips. Armed with array of massive weaponry, that can destroy anything they encounter smaller than themselves. Incredibly costly to make and maintain, technology know how to build them is fleeting (due to the focus of the tabletop game on ground combat and BattleMechs).


 * Word of Blake : This is religious political organization first formed within the ranks of ComStar, the maintainers of the Inner Sphere's interstellar communication. Known for their fanical devotion to the teachings of its founder Jermony Blake, the WoB would evolve into force of it's own once ComStar faced the Clans in 3051, when in 3054 the WoB itself and it's sub-political components would divorce itself from ComStar due to its change of becoming non-political identity. It would eventually retake Terra for itself, and lead charge reform the Star League at the cost massive war when the quasi 2nd Star League collapsed in 3067. Ultimately leading to it's demise in 3081 and it's members hunted down by the Inner Sphere and Clans a like.
