DropShip
Because JumpShips generally remain at a considerable distance from a star system's inhabited worlds, DropShips were developed for interplanetary travel. A DropShip attaches to hard points on the JumpShip, and will later be dropped from the parent vessel after entry into a system. DropShips are highly maneuverable, well-armed, and sufficiently aerodynamic to take off from and land on a planetary surface.
LRM
LRM is an abbreviation for "Long-Range Missile," an indirect-fire missile with a high-explosive warhead.
NEW AVALON INSTITUTE OF SCIENCE (NAIS)
In 3015, Prince Hanse Davion decreed the construction of a new university on New Avalon, planetary capitol of the Federated Suns. Known as the New Avalon Institute of Science (NAIS), its purpose is to recover the lost technologies and knowledge of the past. Both House Kurita and House Marik have followed with their own universities, but neither is as well bankrolled or staffed as the NAIS.
PPC
PPC is the abbreviation for "Particle Projection Cannon," a magnetic accelerator firing high-energy proton or ion bolts, causing damage both through impact and high temperature. PPCs are among the most effective weapons available to BattleMechs.
SRM
SRM is the abbreviation for "Short-Range Missiles," direct trajectory missiles with high-explosive or armorpiercing explosive warheads.
STAR LEAGUE
In 2571, the Star League was formed in an attempt to peacefully ally the major star systems inhabited by the human race after it had taken to the stars. The League continued and prospered for almost 200 years, until the Succession Wars broke out in the late 28th century. The League was eventually destroyed when the ruling body known as the High Council disbanded in the midst of a struggle for power. Each of the Council Lords then declared himself First Lord of the Star League, and within months, war had engulfed the Inner Sphere. These centuries of continuous war are now known simply as the Succession Wars, and continue to the present day. As a result, much of the technology that had brought mankind to its highest level of advancement has been destroyed, lost, or forgotten.
SUCCESSOR LORDS
Each of the five Successor States is ruled by a family descended from one of the original Council Lords of the old Star League. All five royal House Lords claim the title of First Lord, and they have been at each other's throats since the beginning of the Succession Wars in the late 28th century. Their battleground is the vast Inner Sphere, which is composed of all the star systems once occupied by the Star League member-states.
