Ok, I'm going to let my fanboy out to play a minute.
Bruce would never be on a battlefield to need guns. His style is more like a ninja. He would lurk in the shadows and fight using stealth techniques. Also, he wouldn't waste time fighting foot soldiers unless they were guarding the "big boss". By taking the "boss" down (and delivering him to the proper authorities. lol) the whole operation crumbles.
I say eliminate the bat symbol on his chest and have what could be the makings of a pretty cool creator owned story and character.
Critique-- We should see more of the top of the left boot by the perspective of the
ground. Great detail and pose. Face looks great.
