I have no photo's of this type of marking. I would think that white would stand out too much ..... but why not, as it is your model! I have checked closely the images from the fight going on right now over there (the town begins with an "F", but I can't get the correct spelling of the name at the moment!!) ..... nothing new. I have noticed though that some of the Arbams tanks are starting to show the NATO camo coming though the sand coloured paint. Looks like the tanks are getting 'sand-blasted' or used alot and the original camo is now showing up.
P.S. If you can get to the CBC evening news show at 10 PM each night, for the last week they have shown lots of feed from the area above. More than the American networks I have seen. It lasts (the news show) for about 90 minutes each night. Lots of great action shots of Abrams and Humvees, and Bradley's, etc!
