If my eyes (and screen) aren't deceiving me, I'd say that your basic shade OG 107 is what you got on them right now.. The body armor color's right too, although you may want to stain/fade them a bit here & there... Although you might wanna work on those seams a bit more..
Aircrew boots are all black, but a number of them wore jungle boots anyway...
Here's yer basic Jungle Boot... These are newer issue, circa 1990s, but that don't matter in 1/35th scale..
