Yeah, this was strongly influenced by Ryan Stebbins's work, as a matter of fact, I hate to say this, the face ski mask is actually the one from the site, just resized. Credit for the face to Ryan Stebbins. Please review!
About this creation
Yeah, I was trying to get my Ghost decals to upload, but they wouldn't. So you're just stuck with the regular special forces uniforms.
Problem solved!

Quoting Who needs a first name? Or a last name?
If I print this on normal paper, how do I attach it? Do I use glue or something? If not, what type of paper?
I print my decals on Avery sticker paper. You can get it at an office store (label paper also works, just get the proper template).
I'm not sure I understand your question properly, but you should try just loading them in MS Paint, Word, or whatever program of your choice and print it. I made these so one wouldn't need to resize them.
