Hi guys, I'm the Spanish Garrison GML and got a doubt I hope you can solve... This can sound "stupid", I know, but I've been asked if a sandtrooper costume must be weathered or not to enter in the 501st... (some even told me it's NOT necessary). I personally think it's a must, but I'd need to know the official point about this, as I Cannot find the 501st standards about Sandtroopers. No more, thanks for the help. Ben.
