Middle-range strike drones are much cheaper than JDAMs (smaller payload, but you don't care about that against trucks), longer range, and let you operate in fully contested airspace or even when the enemy has air superiority.

Aerial bombs are for entirely different purposes; they're for destroying fortified positions. Whether the aircraft should be manned or not is an entirely separate question, but one thing is unambiguous, it needs to be big enough to carry said bomb (aerial bombs are very heavy).

But again, complete overkill for a transport vehicle.

Re, the terrain of Donbas: compare, at the same zoom level:

Donbas

To a stereotypically flat place in the US, like, say:

Kansas

Unless you mean the "Smoky Hills" of Kansas:

Smoky Hills

Though their relief is only about 2/3rds that of that in Donbas. Donbas's relief is more like that of the Piedmont Province (the area west of the Appalachians), the dissected till-plains of southern Iowa / northern Missouri, the Tennessee / Kentucky western highland rim, or the low glaciated plateaus of the northeastern US (NE. Pennsylvania to southern NY).

It's not as forested as it used to be, but still has sizable patches left, such as along the Siversky Donetsk, mainly pine. Maybe the area east of the Appalachians would be a good reference for the mix of farmland with residual forest patches (well more than midwest states like e.g. Kansas). Defensive lines are commonly built in the forested areas, for greater cover.

Oh, and also (re: NERA) worth noting that there would be a brief boost in energy transfer to the generated gas from cell discharge. You wouldn't come close to fully discharging a cell (that requires lithium diffusion), but it can effectively instantaneously discharge the double-layer capacitance at the electrode-electrolyte interfaces, and very rapidly oxidize lithium at the anode surface (such as the SEI) / reduce species at the cathode. So in a way, not an entirely non-reactive armour, and somewhat reminiscent of the reactive-but-not-explosive NERA variants where they mix nitrate salts into the elastomer to make the reaction more energetic and gas-generating.

It seems that the most effective "drone defense" thusfar has been "moving in small groups or individually, at night or in bad weather, and then hiding in a basement until there's enough people / supplies to push further".

It's clear that armoured vehicle design needs to change. But hangar/turtle tanks hardly seem a durable approach either (even in Ukraine their use has fallen off). I'm still very much a believer in hybrid armoured vehicles, where you have a battery pack with several dozen km of range, and one or more generators powering it.

From a direct survivability perspective, if you use a non-flammable li-ion chemistry (there are plenty, it just means sacrificing some energy density - still requires managed venting / air control systems, however) and have cells in parallel connected by multiple busses, spread out across the vehicle's footprint, it becomes almost impossible to take out the entire power supply, just individual cells. Likewise, since electric motors are compact, you can have 1-2 motors on each axle, and again it becomes almost impossible for a drone to get a mobility kill that way (reducing approaches only to trying to disable the tracks themselves). If they take out the generator/generators, the vehicle still has its electric power to fall back on, and while it's not going to be making some deep push anymore, it can still keep fighting, and retreat when needed.

From an indirect survivability perspective, you have the ability to advance silently when needed (no engine noise, greatly reduced thermal signature), and since modern batteries have so much power density, you have the ability to have a higher top speed, which has proven critical for safety in drone-dense environments. You also have a lot of electrical power, for drone-detecting radars, drone jammers, anti-drone weaponry (lasers, microwave, etc), and so forth.

The mass and volume of the battery pack (we're talking maybe ~250kWh for a rugged heavy armoured offroad tracked vehicle, ~60kWh that for a lighter-armoured road-optimized vehicle) isn't wasted. Cell cans are steel, and between the inner plate and outer armour you're basically forming a honeycomb structure (good for dissipating shocks and spray) with a lot of thermal capacity (cells are organics, e.g. generally high specific heats). With a proper design, you might even be able to get it to function as non-explosive reactive armour. Specifically, contrary to misconceptions that NERA requires elasticity, NERA works instead by a vapor pressure-bulging effect: the interlayer vaporizes and expands violently outward, causing bending of the metal plates it's sandwiched between, so the incoming metal jet is constantly hitting a different location as the bending progresses. NERA normally uses, but does not in any way require, elastomers for this role, simply because they're easiest to package between metal layers, but a properly engineered battery pack should be able to serve the same role. In NERA, you want as much gas pressure generated as rapidly as possible; the copper plasma jet effectively instantly converts e.g. ethylene carbonate, graphite, etc to gaseous CO2, H2O, etc (plus vaporized metals along with the vaporized steel). The keys that matters are that cells that (A) cells that are in parallel are distributed throughout the footprint of the vehicle (not concentrated in a single location), (B) shared buses create multiple distinct parallel paths between the cells within a given parallel group, and to the next series group; and (C) (required for any NERA) that generated gases are properly vented / handled.

A number of next-generation armoured vehicle designs are pursuing hybrid propulsion.

. I believe the record for most FPV drone hits survived by a single tank in Ukraine is now thirty-two,

The value of 32 small FPV drones is way less than the value of one tank. And in general you're likely to be talking about "hangar tanks" / "turtle tanks" when talking about things like that, but these take on *massive* disadvantages, including being extremely visible and easily targeted by larger drones or artillery (as well as bogging down easily, difficulty getting through confined areas, poor or no gun maneuverability, etc).

it's mostly flat and open.

Donbas is mostly rolling hills, much of it forested. And much of the combat has been in urban environments, which is about as complex terrain as you can get.

cheap FPV drones don't work if the other guy is on the far side the hill you're hiding behind, for example.

Uh, yes they do? They literally fly.

Small drones are munitions, and need to be thought of as that. Even non-FPV drones generally have quite short lifespans - for the smallest categories, just a few missions before they're shot down, jammed, or otherwise crash. They need to be stockpiled the same way you'd stockpile grenades or artillery shells (with the caveat that you'll have a much faster upgrade cycle on the electronics, and need to enable that). It also means short-cycle-life secondary cells, or even primary cells, as the power supply. E.g., with current tech, lithium metal or lithium sulfur are good candidates.

Middle-range strikes are increasingly proving invaluable as well in Ukraine this year. The ability to affordably take out a fuel or ammunition truck dozens of kilometers behind the front line is key.

It doesn't have to be the way it is, guys. You genuinely can just fix all of the things that are wrong in your system. But the first step is understanding that said things can be a lot better, and are elsewhere.

And I want to be clear, this isn't an "everything in or about the US is wrong" post**. This is about "US infrastructure in general" - the focus being on digital infrastructure, but arguably, it applies to physical infrastructure as well (the US is a laggard on high-speed internet, its electrical grid is famously unreliable, US high speed rail projects have been one disaster after the next, etc etc).

** If you want me to sandwich in a "US thing done right" as a counterpoint: the EU is politically dysfunctional, with any one state being able to veto collective action, allowing rivals to pick us apart one at a time. We have no common defense. Also, each state sets its own contrasting economic policies, yet all are on the same currency, so each one can drag the other down. I want to be clear, this isn't an "everything is perfect in the EU and everything is wrong in the US" post, the EU very much has its own problems! This is a post very specifically about US infrastructure compared to the rest of the world - and it's not simply a problem of funding. It's a problem of the US just running off with incompatible siloed system with hack patches tying them together and never putting forth any meaningful effort to fix things, with most people not even aware that you can do things better, and that most countries do.

US prescriptions are still sent to individual pharmacies. There is no nationwide system where any pharmacy can just look up the prescription of anyone who just walks in, right when they walk in, instantly after the person walks out of the doctor's office

And there is absolutely no need for "24 hours". The medications are all on shelves in the back. All they have to do is grab them and put them in a bag. We're not talking about compounding pharmacies here.

Also, we're not a "homogeneous population", you can stop with your pro-racism stereotypes. Immigrants are 20% of our population.

Being big is an advantage, not a disadvantage. It means that the costs to develop a system are spread across a much larger population. Everything we have had to be developed on a comparably minuscule budget.

I've actually programmed quantum computers, and I have to admit this is correct. We have access to more qubits now than we can effectively use because of the rapid accumulation of noise and decoherence in quantum processing. No one seems to have achieved much with Quantum Error Correction, and schemes to get it to work better (like Cat qubits) remain theoretical.

There might be a breakthrough someday, and when it happens everyone will know quickly, but there is still a lot of work to do to get there. Or there may never be a breakthrough.

I just asked Google in AI mode "qiskit bell state" and it gave me the code.

from qiskit import QuantumCircuit
from qiskit.quantum_info import Statevector
from qiskit.visualization import plot_histogram

# 1. Create a quantum circuit with 2 qubits and 2 classical bits
qc = QuantumCircuit(2, 2)

# 2. Apply a Hadamard gate to qubit 0 to create a superposition
qc.h(0)

# 3. Apply a CNOT gate with qubit 0 as control and qubit 1 as target
qc.cx(0, 1)

# 4. (Optional) View the ideal quantum statevector before measurement
state = Statevector.from_instruction(qc)
print("Statevector:\n", state)

# 5. Measure both qubits into the classical bits
qc.measure([0, 1], [0, 1])

# 6. Draw the circuit text representation
print("\nCircuit Diagram:")
print(qc.draw(output="text"))

You can go run it on IBM Quantum Platform or AWS Braket

And I want to be clear in the above: I fully acknowledge the irony, in that the US tech industry has been a powerhouse. There seems to be a massive disconnect in the US between tech innovation and tech infrastructure. The US is a world-leader in the former. It's consistently a deep laggard on the latter. The reasons why the US has so much trouble getting its act together on infrastructure and systems are complex, but it is remarkable to see, as someone who has spent their life in a mix of the US and Iceland. And it's not just Iceland that has it's act together on these sort of things - it's most of the developed world, and even surprising amounts of the developing world.

, with the most sophisticated banking system

Any American who believes this should try living overseas for a year or two. The US banking system is insanely backwards. Numerous aspects of the US medical and government systems as well. It's hard to explain it to you unless you experience it.

Checks are just one symptom (in Iceland, 15 years ago bank tellers would look at you weird and have to get the manager if you had a personal check, and 10 years ago, stopped taking them altogether). For like 15-20 years, we've had free instant bank-to-bank money transfers (no third party involved), everyone on the same service, to the point that if someone is collecting money for a gift for a coworker's birthday, it's always been, they just send an email with their bank details, instead of going around and collecting cash. All your bills - all of them - just show up in your bank's inbox. On and on.

I mentioned the medical system. Let me give a random example. In the US, you go to a doctor and they determine you need a prescription. They or their receptionist have to ask what pharmacy you want it at. It gets routed through SecureScripts (before that, it was all phone based!), and depending, you may also need to also call into the pharmacy before you go there - and if you need it "transferred", it's a multihour process. Here? The doctor just jots it into their computer, that's it. You can literally just walk out of the doctor's office into the pharmacy next door (or any other pharmacy), tell them your name, and they go grab your order.

Everything is connected. Everything is interoperable. All keyed to your kennitala (ID number) . And the kennitala is only a key, not a password. The fact that a SSN in the US is treated as both a key and a password is insane, from a security standpoint; by contrast, you can just post your kennitala online, it's fine. We have multiple actual authentication methods. The most convenient is the Auðkenni system. Our SIM cards store credentials in a separate cryptographic chip. When we need 2FA, for any business or government agency (all on the same system), it sends a special SMS that the phone routes to the SIM card to process, and then (at the OS level) pops up an authentication dialogue, so we have universal 2FA, linked to our kennitala, in all of our phones. It's been this way for like 15+ years.

Or let's talk taxes. You all know what it's like in America, so let's explain what it's like in Iceland. I get an email letting me know it's tax time. I go to the tax office website. I get 2FA login via my phone. My tax forms are right there. They're already filled out, with all of the information already collected. For like 90% of the population, it's just click through, verify it's correct, and submit. Some people may have some things that weren't logged, such as overseas investments or whatnot, but for most people, it's like a five minute process.

On and on. It's been so weird seeing America getting things 1-2 decades after us and acting like, "wow, we're leading in banking technology!", etc. No, you're an aged dinosaur, way behind the rest of the world because none of your systems work together and you're so slow to adapt to change.

Sigh. Ontogeny is NOT evolution. It is not the same thing as having a low MHC diversity due to a genetic bottleneck as well as lacking tens of thousands of years of evolution to a pathogen. Not the same at all. It's silly to even suggest that. Epigenetic shifts in an individual do not create new HLA genes.

Consider COVID. Novel bat coronavirus, nobody had preexisting immunity. Did everybody die? No. Because we had high HLA/MHC diversity, making it easier to target SARS-COV-2 epitopes. Native Americans lacked this diversity. It left them ill prepared for novel pathogens.

Also, you seem to believe that any disease you've never encountered before is fundamentally dangerous to an adult. That's simply not the case. Rhinovirus is intrinsically mild. It's an upper respiratory infection; it's not adapted to lower respiratory or systemic infection. It's not ebola. It's not going to become like ebola just because you've never caught it before. If a rhinovirus strain was reintroduced after 200 years after having been eradicated, we'd all get a cold, but by and large, we'd be fine.

And what would happen if Yamagata reappeared? We'd just add it back to our flu vaccines. Furthermore, the reintroduction of Yamagata wouldn't be catastrophic without that. You do not have to catch every Influenza B lineage at all, let alone every year. If you had been infected with B/Victoria and you were exposed to B/Yamagata, you'd have little sterilizing immunity against it - you'd very likely catch it. But your past exposure to B/Victoria is still greatly protective against hospitalization and death; B and T immunity against NA and the HA stem and stalk are conserved.

And this is about whether or not to catch every lineage. Well guess what, even with air filtration, that's still going to happen. Air filtration only has a meaningful impact for people at a distance, not people close together. It's about protecting the person across the room, not the person you're standing 50 centimetres away from. What it does change is how often you catch them. And if lineages or whole viruses go extinct, that's great. Worrying about some sort of reintroduction 200 years later is just inventing your own unrealistic misery when we have actual pandemic threats to worry about.
