Very well done. I’m not too concerned about the helmet band. Soldiers tend to do whatever suits them once they’re away from the flagpole.
The arrangement of the kit - some things are less egregious than others. I’ve seen some pretty whack shyte myself. I wore a thigh rig in Afghanistan. But never on the rare occasions I was actually inside a vehicle.
The thing that makes this slightly less than a perfect figure for me is the painted on chevrons. Right or wrong (Hell, they wore them on Aliens) they need to have a bit of thickness to them - paper, putty, lead foil or whatever you choose.
