The answer to your question is become we simply do not have the funding to create such armor systems as of late. The technology that which is featured in this armor does exist, however. The problem with these technologies being that they are still not perfected and/or fine tuned for the applications that which this armor is supposedly capable of. Though hopefully this armor will be available for our military, I know that I'd much rather have this gear on than what he have now.
Exactly. 2000 dollars. To outfit the entirety of the US Military's infantry with that kind of armour would be far too costly. At best, it'd be armour for special units. Not only that, that armour would be quite cumbersome, so mobility would be a problem as well.
I don't know how much money US Infantry armour costs, but I doubt it's that much.
Actually our standard issue rifleman kit adds up to about 2,500 to 3000 dollars with all the equipment costs added up.. that's not including soft body armor with SAPI plates inside the vest, or weapons costs. They spend quite a bit on us.
