Looks pretty nice. I doesn't have to be sand. They are also in NATO camo.
You are not incorrect in overall green either. They have been seen in Europe recently on Operation Atlantic Resolve rotations in overall green. It is a temporary paint used to cover sand vehicles in a more Europe-friendly camo quickly.
As to hipshoots, yes they are still practiced. They are much easier with the Paladin though since each gun has GPS onboard and knows exactly where it is at any given time. Simply receive the mission digitally, stop, load, hit the lay button and the gun slews into firing position (both deflection and quadrant), and fire.
