Top Marine wants to lighten the weight carried by grunts

I was on a jump with a reserve SF team in '87 at Pine Bluff Arsenal in Arkansas. It was part of a holiday demonstration, and they showed off all sorts of new things, including caseless ammo. I wonder what ever happened to that R&D project. Is it like our much-promised flying cars?

Great! Lighten the load to make room for more ammo and MREs.

Outstanding idea!
