One thing that stood out for me in that video right... long hair.

They all have very nice long hair.
Are male soldiers even allowed to have long hair?

Would that not be a potential liability in combat?
I know in a fight (like a regular street fight or whatever) long hair can spell doom for an opponent if it gets grabbed.

How about visibility?
If those ponytails come undone during an intense firefight and the soldier is supposed to be giving cover fire or something and at a crucial moment his/her visibility is obscured by hair?

It's a weird little detail I know, but it just struck me as I watched.

Any military folks got an opinion on that?

Am I talking shit here or what?
Is it irrelevant?
