Perhaps you have some clear evidence to counter the articles I provided?
The weight is not going to go down.
The one from the GAO talks about how the minimal equipment is about 120 pounds. And that is just the basics, including body armor, weapon and ammunition, and food and water. You just can't get it any lighter, period.
Just the body armor alone is around 50 pounds. And that is up significantly from the PAGSAT system we used in the 1980s and 1990s. The amount of water has also increased significantly. Up from around 4 pounds of water to the current which is over 10 pounds of water. I can go on and on, but I doubt you will care.
I first joined in 1983, and just recently retired from the military. I have seen the weights increase over the decades, and most of it was for damned good reasons. And absolutely nothing seems to be happening to decrease that, but instead will make the wrights even more. I have absolutely never seen military gear other than radios and other electronics like night visions, LASER designators or GPS get smaller. Absolutely everything from backpacks and sleeping systems to tents and everything else has always gotten larger and heavier.
At my last units, they always laughed when we were doing a "conditioning march", and instead of the MOLLE pack I elected to use my own ALICE (large) as it was simply a superior pack that was better than the MOLLE is.
I think the biggest problem is you are believing things you are reading on the Internet, and not actually applying actual real world or personal experience at all. Everything had gotten heavier, and will continue to get heavier.
And a "Forced March" is not a "walk". It is far closer to "speed walking" than what you would do just strolling through a park. On average a 6 mph pace, 100 steps per minute. Covering about 5 miles in an hour, then taking a 10 minute break before you rinse and repeat for another hour.
And the above is just a "conditioning hike", that is not even under the full combat load. No body armor, no weapons, no helmet. Probably just doing 5 miles or so from the barracks and back.
And the above weights? That is the lightest you will find, those are for the "Rifleman".
If you are in the "Weapons Platoon" or "Weapons Company", it only goes up from there. If you are the crew of an M224 60mm mortar, add from 10-15 more pounds each plus. Each member in the 3 man team is going to have all of that above, and add those weights for the various parts of the mortar. Or if heavy mortars (81mm), grab your sack. That is an additional 90 pounds, split among the three man team. The worst being the 35 pound mortar tube. Plus ammo weight, from 3 pounds for the 60mm to 10 pounds for the 81mm. And that is per round, each member will be lugging from 3-6 rounds each in addition to everything else.
8 grenades each, that is about 8 pounds.
I was a Combat Lifesaver, add another 6 pounds or so.
