Reported recently by Popular Mechanics (a surprisingly good source of reliable military information) is a new technique introduced by the US forces in Afghanistan. This is the GPS-guided or "smart" parachute – known as the Joint Precision Airdrop System (JPADS).

It can be used by high-flying transport aircraft to make precision drops of supplies to isolated outposts, reducing the need to use ambush-prone vehicle convoys and avoiding the hazards involved in helicopter re-supply. So successful has been the technique that the USAF delivered 313,824 pounds of supplies between August 2006, when the programme began, to September 2007 – keeping an estimated 500+ convoys off the roads.
First time I've heard of it but as it is a few years old I assume most of you will know about it?! It mentions here the supply of outposts but would this system work for supplying small patrols? Even from helicopters at altitude. What say you......
