The first Z-10 had extra composite-material armour panels attached to both sides just below cockpit windows.

There appear to be two people sitting in the cockpit of the first helicopter. Other helicopters might also have people in them. Meanwhile, the grass on the ground appears to be yellow. All the helicopters appear to be black in the image, which appears to have been taken during daytime. I believe those buildings in the background might be hangars and control towers, and they have what appear to be blue roofs. The structures might be made of reinforced concrete. Also note that all the helicopters feature rotors, and they appear to be hovering in the air. Speaking of air, even though you can't see it, but helicopters need air to operate.
I'm surprised you missed all these details. Let me know if you think I've missed anything.
