JHMCS isn't that useful in such extreme off-axis situations. A missile taking a big turn requires it to expend a lot of energy and drastically hampers its probability to hit the target.

I mean for the Russian driver. And yes... bummer... but who can turn their neck that far? Don't forget eyeball gimbals don't count.

Maybe they'll start adding certain neck mobility requirements in the anthropometric screening? It's a brave new world...
