Yes, you can tell Alex Ross is a genius because he's managed to do something even Jack Kirby never could.
Namely, rip off The Shield
That's what I thought of too, except I couldn't remember the character's name, having only seen him in a compendium of Golden Age covers I have. I can't help thinking that Ross is also rehashing his character design for The Silver Agent in Astro City, what with the guns and all.
I suppose the guns are also a result of the gung-ho, hawkish trend that seems to be pervading many U.S. comics (especially Marvel), which probably reflects of ongoing conflicts; it's almost as if Captain America is returning to his original WW2 roots.
