From my personal-who-knows-when-it'll-ever-come-out-espionage-epic "Off the Grid"
United States Marines as they appear in the story, circa 2017.
Since the end result may be animated, the camo pattern may be dropped, but I chose woodland MARPAT simply because I like it better than the desert one and at present, it's the only truly green uniform left in the US forces.
Gun design is based off the Mk 16 and Mk 17 SCAR. Traditionally Marines are rifleman by doctrine, but I drew a carbine just because it tickles my fancy. They're all tan right now, I figure green versions will come around eventually. At this point, I think mixmatched equipment colors due to supply problems are a trademark of the US soldier 'look', so I thought I'd echo that in the modular components of the weapon.
I went with a hard visor instead of clear plastic mostly because I think the next big advancement in soldier equipment will mostly be advanced optics and an emphasis on awareness. The user would actually be looking at the combined images of several cameras mounted both on the helmet and weapon system for a wider degree of vision than normally possible for the human eye. Not to mention as gun camera technology progresses shooting from behind cover or from the hip will become all too easy.
Yes, I've put too much thought into it. Photoshop cs 2 and intuos 3 as always.
