Army R&D delivers 'greatest inventions' (photos)

M320 grenade launcher

Every year, the U.S. Army recognizes the ingenuity of its soldiers and support staff with a list of what it calls its top 10 inventions for the preceding calendar year. And every year, that list seems to come later and later--when we first started tracking the achievements in 2007, it was June, then that turned into September, and for the latest list, November. So without any further delay, we present to you the U.S. Army Greatest Inventions of 2009.

We'll start with the 40mm M320 grenade launcher, fielded in June 2009. It's the chunky piece of gear attached below the barrel of what looks to be an M4 carbine (it also attaches to the similar M16 rifle); the 82nd Airborne soldier is holding its pistol grip with his left hand. LINK
