This is what "classes" exist so far in the White Legion. This will be updated whenever a new class appears in the comic (or, more likely, just before).
About this creation
First, The generic soldier, with his double-barreled hand gun and black visor for the back of his helmet
The pilot, his handgun, and his light blue visor
The sniper, with his sniper rifle and his green visor
The rocket trooper with his jetpack, flamethrower and dark blue (will be changed to red) visor
And finally the Heavy Weapons Guy, with his yellow visor and Atmospheric Energy Redirection Cannon (AERC)
Just one today
All White Legion weapons are powered by the alien element "Sapherium (may be subject to change), which the rebellion has very limited access. The AERC works by redirecting the huge amount of energy left in the atmosphere from the Great Mech War through an energy conduit and into a small forcefield projected by a weakly constructed prejector designed to shatter on impact, releasing a petawatt of energy into the surrounding area, causing huge destruction as well as destroying organic tissue and frying machinery.
