There are a few things to be optimistic about in terms of weight savings. The first is a slew of somewhat new materials such as Blue Force Gear's Helium Whisper, which is significantly lighter, stronger, and more abrasion resistant than standard 1000 weight cordua nylon. With Helium Whisper and similar materials, we are starting to see some plate carriers, chest rigs, pouches, etc with huge weight savings and much slimmer profiles over standard counterparts. It is understood that the vast majority of conventional units won't be rocking the latest breed of plate carriers anytime soon, but it is at least a positive indication of things to come. In the meantime, many conventional units are ok with their men shaving a few pounds with better pouches and web gear.

The second aspect to be somewhat optimistic about is ammo weight. More SOF units have become comfortable with a 4-magazine loadout for their m4's, mk18s, etc. The readably accessible AAR, "The Eagle Went Over the Mountain" has a good reference to this. Better training, better optics, more accurate ammo, and increasingly accurate weapons have led to more accurate target engagement. However, it will be interesting to see how, or even if, this plays out in conventional units in the future. Less training = more rounds spent, and more ammo required. Furthermore, with the USMC and the m27 IAR, many infantry squads are finding themselves carrying more magazines than ever in order to spread-load the weight/bulk.

Finally, improving load carriage techniques have begun to not necessarily lower the weight, but to improve mobility and performance. Wearing a plate carrier or full armor vest with double m4 pouches all in front makes shooting in the prone an art-form, not a comfort zone. All the weight on the shoulders sucks. The first generation of the USMC MTV's that came out were heavy as hell, but were supposed to transfer weight onto the hips more. Me and my men didn't notice much of that, but we did notice our hips being worn raw by the placement of the side SAPIs. That actually became a planning consideration for me as I alternated mounted and dismounted patrols for the squads of my platoon. In a "back to the future" move, you see more guys now slimming down what they put on the front of their vests, and putting more ammo and kit on padded warbelts. The new generation of packs such as the USMC Pack are finally designed from the ground up to integrate with armor. When significant weight savings are impractical, improved load carriage is everything.
