Can you imagine moving long distances or fighting for your life on uneven terrain with all of that stuff dangling off of you and weighing you down? Also notice that the soldiers behind him have full cargo pockets on their pants.
It's interesting to notice the interplay of how new technology enables the soldier to carry more gadgets and tools, but simultaneously makes the old gadgets lighter.
A typical soldier has more in his first aid pouch (one of those dangling tan things with a zipper) than the platoon medic did in WWII. His rifle is lighter, but it also has an advanced optic and a laser visible through his NVG's. He's carrying a vest with a "bullet proof" plate (very heavy) but under it is a shirt made of light durable technical fabric that wicks moisture away from his skin.
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.
