Interesting you mentioned exoskeletons. The US is 5 to 10 years away of getting them on a battlefield. They're commercially available in Japan for medical use. (I'm not making a value judgement on that, except to the extent that "You could actually buy this" is superior to not being able to buy it.)
Actually that's a very good point, and a fascinating demonstration of the differences in commercial funding for a technology vs military funding and the similar but completely different kind of tech that comes out of that.
