LANCE

A lance is an Inner Sphere BattleMech combat group, usually consisting of four BattleMechs.

LASER

Laser is an acronym for "Light Amplification through Stimulated Emission of Radiation." When used as a weapon, the laser damages the target by concentrating extreme heat on a small area. BattleMech lasers are designated as small, medium, and large. Lasers are also available as shoulder-fired weapons operating from a portable backpack power unit. Certain range finders and targeting equipment also employ low-level lasers.

LRM

This is an abbreviation for long-range missile, an indirect-fire missile with a high-explosive warhead.

OMNIMECH

The Clans' military success against the Inner Sphere is mainly due to the OmniMech. Based on advanced Star League technology that the Star League Defense Forces took with them when they left the Inner Sphere, Clan scientists developed the OmniMech, a BattleMech whose modular weapons systems could be easily reconfigured to suit any mission. This innovation gave the Clans tremendous flexibility on the battlefield. Coupled with their vastly more efficient cooling and sensor systems and destructive firepower, the OmniMech made the Clans virtually invincible. Since encountering the OmniMech, Inner Sphere scientists have tried to incorporate Clan technology into Inner Sphere 'Mech designs.

PLATOON

A platoon is an Inner Sphere military unit typically consisting of approximately twenty-eight men, commanded by a lieutenant or a platoon sergeant. A platoon may be divided into two sections.

PPC

This abbreviation stands for particle projection cannon, a magnetic accelerator firing high-energy proton or ion bolts, causing damage through both impact and high temperature. PPCs are among the most effective weapons available to BattleMechs.

REGIMENT

A regiment is an Inner Sphere military unit consisting of two to four battalions, each consisting of three or four companies. A regiment is commanded by a colonel.

SRM

This abbreviation stands for short-range missiles, direct-trajectory missiles with high-explosive or armor-piercing explosive warheads. They have a range of less than 1 kilometer, and are accurate only at ranges of less than 300 meters. They are more powerful, however, than LRMs.
