For one that "face mask" you speak of is already in the game (just look at the pic at the top of the page between the TC:E task bar... what's that guy wearing over his face?).
For another, English is my first and only language, and I don't beleive any of your pics are in any way an inspiration.
The specop pic you displayed is that of (I do beleive) an Army soldier in desert camo. The Army has a different look than a Special-Operations unit.
Special-Operations.... you know... like SWAT. They are not going to have the same equippment, and they are not going to have (strongly) similar uniforms. Specops are decked out with urban-assault gear and uniforms.... the guy in the pic you showed is decked out in a desert-assault type uniform, and has corresponding gear.
Oh yeah, and as if the terrorists really need to look like that
... all I see is some chick in a back track-suit, no bullet protection, and a freaking beanie (and all her equippment is hung over her back).
Oh and for the record, you aren't the most imaginative and creative person in the world, I easily out-rank you in that department.
