AS7-S Atlas
Insignia:
The Thumpers’ insignia is a white fist on a purple background; originally a right hand on a blue field, at some point the insignia made a mysterious change to a left fist on purple. For acts of selfless heroism that save Thumper lives, individuals are allowed to display the logo with the fist pointing downward. Per FM: Mercenaries Supplemental, page 63.
