The lack of HUD strikes me as unusual. No real snags as all the info can be projected onto the helmet visor but that thing is going to end up weighing a ton under 'g'. It's okay for the Apache boys to have a helmet with lots of added extras but that F35 helmet weighing around 4 kgs at rest suddenly becomes 36 kgs while you're pulling 9 'g' around the circle, chasing after the bad guys. There's going to be some really big necks in the Flying Watches Bar.
PS: You'd think someone could have painted it all one colour, without all the zig-zaggy bits, wouldn't you?
