does this help at all? UNSC logo. I dont know i did a google search to try and help. Hope it helps you. copy it in to word and make the back ground black and then it might work.
What color do you want the logo foreground to be, and.... do you want it to say 405th or UNSCDF?
Here's what I did to 405th's logo in photoshop (and I made it blue). I can either tell you how, or just do it again based on your criteria. So.... what are you looking for?
