there is a huge amount of politics regarding this armor and its adoption or rejection by any US service. its a local story around here, so i've taken some interest.
it appears to be a very effective armor that is unfortunately getting smeared by one rather ridiculous air force test involving weapons fire from calibers the tested set was not even rated for.
the competition took that and ran with it. pretty unfortunate, becasue i believe those attempting to discredit the product sell high quality, but previous generation tech to our soldiers, and are worried about losing a contract, as opposed to the safety of our soldiers.
