>I'm convinced there will never be a day when the infantryman isn't carrying too much weight. There is a limit to how much weight a fit infantryman can carry and still be able to fight and they will always have us carrying stuff up to that limit.
That day will be when we have sustainable mechanized body armor. When the suit can carry more than the man wearing it, the man is no longer the bottleneck.
The question will be whether we just send drones at that point.
