If using Vallejo, I'd go with a base color of 120 for the light khaki, and then splotch 77 (bright green) over it.
74 would be another alternative, but looks to be slightly darker.
Both of those will get you in the ballpark, I think.
Always a bit hard to tell, since the Vallejo paints sometimes don't match up with their paint chips too well.
The color you want is a flat, bright, olive green color, based upon the uniform I've saved a sample pic of, on my PC.
Note – the guy is also wearing a facemask with the same camo, to match, which should certainly make your life easier.
I think this is an airborne, and/or other special forces uniform, e.g. Border Guards, Spetznaz, etc..
