I’m taking Richard’s advise and renting a Wolverine before I buy.
If someone could build a .308 that weighs 7 lbs, has manageable recoil (for the average soldier—I used to shoot a .300 Win Mag) and 30 rd mags, I think that is a solution. I think though whatever solution they come up with, they have to reduce the pack weight. Adding body armor to every soldier is where we’re headed and that is nontrivial. Adding 15 lbs to weight already carried is asking a lot. We need to make it up somewhere. BTW, I have backpacked thousands of miles of wilderness with an 80lbs pack over decades. I know all about what is possible. Adding 15 lbs is a very serious issue.
And let me digress a moment to SC.
I’m a proponent of “light builds” in fps combat, meaning keeping your weight below 15 kgs when you drop your pack. This is really hard to do, but it yields 100% movement rate which none of the NPCs can hit and only very few PCs can hit. If you follow Star Marine, ALL of the top players are “dex tanks”, or very high mobility shooters, who normally sprint and fire from the hip. The new Palatino Digital Helmet actually helps you aim from the hip and the Lumin V is the meta for doing this.
In order to go below 15 kgs total carried, you can wear any helmet (they all weigh 2kgs) and a medium torso (they all weigh 5 kgs), and no other armor. If you carry a light SMG like the Lumin, a Multitool as you want in the PU, and 3 grenades, and 6 batteries, you are already overweight. That’s how hard it is to get 100% movement. Sometimes you’ll leave a grenade or battery behind, which is irksome. Sometimes leave your Multitool in your pack, which hinders healing, but if you don’t get hit that doesn’t matter. (BTW, the Multitool gives a tiny fraction of overdose compared to the healing pistol. It’s a much better solution until you assign a medic who heals at range.). Some choose light torso.
We’re pioneering some new techniques. Odd as it may seem, dropping the Lumin for an Arc Light and light arms protection is a viable option. Knife takedowns become much more appealing when you move that fast. People are planning to optimize dex tanks around use of the Vanduul Plasma Lance. All manner of options are presenting themselves.
The point is, light makes might. Speed kills. First to Target with their weapon is much, much more important than Time to Kill, because opponents can’t shoot while they’re being shot. So light weapons on lightly armored PCs, running at 100% and firing from the hip is often the way to go; which means every kg matters.
