Steel Fist
Mercenary unit in tanks and tank operations. Served as part of the Returners Expeditionary Force in the Leviathan War; also played a role in the New Wraith conflict. Since then, they've kicked around the Web's various 'small wars' in Ticondera and elsewhere. They have a pretty good reputation, as far as mercenary units go.
Equipped mostly with Kuat Steel Lynx tanks these days, though some of the group's more dedicated Zipperheads have custom jobs.
