I have seen pics on Fox News of Humvees with a 2-tone sand scheme in Iraq as well.
Also, there is a Humvee overhall factory in ME (stateside) that takes older, battle damaged Humvees, and rebuilds them to new standards, and sends them back to Iraq and Afghanistan.
The show I was watching showed newly painted Humvees painted in a 2-tone sand scheme similar to this M1A1 Abrams.
I agree, a very interesting scheme for a US vehicle.
Thanks for posting the pic
Cheers !!
