I see a split chin on that bar. Even at low speeds, I have seenlenty of people go over the front. I would not think it needs to be nearly that high. Just above the bars would work.
The bar is pretty dumb. I've rolled a lot of ATVs in my life and I don't see how that bar would do anything but get tangled in brush all the time.
But not wearing a full face helmet is almost as dumb. I've broken the jaw on a couple different helmets, one time just from smacking the handlebars. Had a friend lose both front teeth from the handlebars too, another friend got a server concussion and put a dent in the back of his helmet the size of your thumb, he would obviously not have lived without the helmet. And my GPS tells me my average moving speed is consistently 7mph...I'm no speed demon.
Can't say I care for all the speed holes in the plating, although the armor looks intelligently laid out. For my uses, holes like that would just grab muskeg and snow and be an annoyance. My current machine has some lightweight framework that I put on there that supports some 1/2" UHMWPE that runs from the bash plate to the rear swingarm. You can take the claw of a framing hammer and hit the plastic as hard as you can and not do more than a small scuff mark. Probably only weighs 10 lbs and it slides smoothly over all surfaces.
The areas that take the worst beating when I roll are the corners of the rear rack. They're never supported well and there's a lot of leverage on them. My handlebars have never gotten beat up because I carry two 2.5 gal gas cans and an action packer on the front rack. They are about the same height as the handlebars, but don't interfere with my hands when turning, so they spread a lot of the force out when I roll. The weight on the front tires helps a lot to reduce the frequency of rolls too haha.
As for the Polaris, I wouldn't own another if you paid me. The magnetic hubs will engage without warning when the craptastic electronics act up. Going down a hill in 2 wheel and having one hub engage spontaneously is a great way to test the handlebar durability during a rollover. Not to mention how awful CVTs are for technical wheeling where you need off-idle torque. And god forbid you ever drive the thing in 12" of water or more and the belt looses all its friction. Belts belong on snowmachines, gears belong in ATV trannys.
edit: NM, didn't think about airdrop uses. I've done a lot of stuff with ATVs, but parachutes were never involved lol
