=== Canon vs Not ===

The Fluff is rephrased Canon, but the RPG Stats are derivative using the IPCR for the Damage Stats, and doing a formulaic extrapolation from 180 meters at Short Range to the MechWarrior, Third Edition ranges incorporating the +1 modifier that a "Regular" MechWarrior Starts at in the RPG in addition to the +2 bonus that Combat Vehicles and BattleMechs get because they automaticly carry the equivelent of an Advanced Fire Control system.
