Type 15 Light Tank...what did they blur out in the background?

Click on the above pic to enlarge but you might be able to make it out without even bothering to do that.

Do you see the blurred sections?  The Chinese usually don't do that on released pics.  I imagine its pretty easy to ensure that you don't have classified items/sites in the background.

This time they didn't.

What don't they want us to see?  Utah Bob talks about their version of our National Training Center (been digging into that too...the Chinese are getting real real real big on maneuver warfare!) but I can't imagine that they're trying to block buildings to monitor exercises.

Any guesses?
