FIELD NOTES: When engineers designed the Thor, they borrowed concepts from other ’Mechs such as the Warhammer, Marauder, and Victor. The result was an OmniMech with excellent versatility. It has an advantage over other heavy ’Mechs in that it has a good blend of maneuverability and heavy firepower, with the ability to strike from all ranges. The Thor is well suited as a backup to heavier ’Mechs on the battlefield and is a favorite among the Jade Falcons.
