This is my banner for my Badab Crusade Army carried by a Mantis Warrior Space Marine. Its big, its cool, and contains a bunch of interesting iconography. See if you can figure any of it out. The pole is made out of a long tube of brass, topped by an Aquila. The banner is flanked by litanies of purity, honor, achievements, and crimes of the Badab traitors.
Shown above is a side view of the Mantis Warrior. I used Dark Eldar jaggedy bits behind the forearms to carry the Mantis claw arm theme from the dreadnought onto the rest of my Mantis Warriors. I'm pleased with the result.
