Holy smokes! The EXACTO guided ordinance program is pretty amazing.
This video by Dark Footage does an amazing job of explaining and demonstrating how a small-caliber guided bullet was developed and just how amazingly accurate it is. The weapon is so accurate and easy-to-use that evidently first time users can hit moving targets at distance. Oy vey.
Now watch some asshole sniping at Steve McQueen and Yul Brenner get what they has coming to them.
