A Fanon clone- and Stormtrooper- legion Created by Harrison Kenney, led by Commander Reno(http://swfanon.wikia.com/wiki/Reno), and nearly unknown because of it's being in the shadow of the 501st and their prestiguous honors.
I'll tell you about the background of the 747th. They are Fanon, made by me. There is full information about the Commander, Reno, on the site linked to on the group home page. The Legion's colors are purple and blue, in many designs. The designs indicate rank. The helmets do NOT have the trademark fin. They are equipped with DC-15Ss, DC-s,Z-6 Rotary Blaster Cannons, PLX-1 plex rifles, and the rare occasion of a trooper with a DC-17 Interchangeable Weapons System. They have no Jedi commander, and are basically loose cannon until the Chancellor gives them a new order. The amount of independence led to many desertions to Mandalore during the Great Jedi Purge. Reno himself deserted in 1 BBY.
Would you participate in a contest for 747th ODL members, if one was held?
