I understand what you're saying but and I agree but what I'm saying is they couldn't design this to look a lot better. I am not exactly one for looks but this to me just looks like sending a bunch of sick people to fight. I was hoping for something like this example. They don't even need to be high-tech or expensive, just less silly looking.
Yeah, but you can't go into combat not looking fashionable.
I don't deny that but a mask isn't that much more of a hindrance either.
I think I have the perfect compromise here: camo tubes. Paint the oxygen tubes with a camo pattern so the soldiers can look fresh and not like COVID respiratory patients.
Smart, It's can give the soldiers oxygen with the bonus of making the enemies die laughing. 2 birds one camo tube.
The only other countries which plan for combat at such altitudes are Pakistan and India. Maybe Bolivia and some of its neighbours.
