My .02,
Well painted figs. The sunglasses work well!
Now to a highly subjective critique from a washed out film critic.... I don't like straight black in large areas. Maybe put on a grey striped camo pattern to break up the black a bit? Or perhaps green camo striping, and paint the padded area of the kneepads some other color (olive drab?), again to break up the solid black. My personal preference, is to work as many colors in as practical, but the colors can be muted to keep the "stealth" look you are after.
Even with my personal aversion to black, the figs do look good. Nice job on the various Stars and Bars motifs throughout. Even with their current black scheme, they would be a nice addition to any table.
...and remember. If you're going to have a war in the jungle, you might as well clash!
