Hey Gradenko and/or DD, you were reading a book about artillery called something like "Fire Power". Was it "Field Artillery and Firepower by Maj. Gen. J.B.A. Bailey"?

I'm also taking a recommendation on US doctrine in WW2 compared to today. This is mentioned a lot but I'm not sure if there's a single book to read.

No, though Bailey's book is the gold standard for a technical history of the arm. Fire-Power is by Bidwell and Graham and is a much more enjoyable, approachable, read.

so, about that spending

first of all, there's the old problem of economic efficiency and efficacy - how much gets spent and how much does that spending addresses the material problem it is for. GDP by itself is meaningless with those considerations in mind. If the PLA represents a proportionally smaller budget slice than NATO's defense, but has all its concerns satisfied well enough, that means there is a positive economic relationship in terms of utilization of resources.

and to have efficiency and efficacy, an economy requires a certain level of aggregate development in order to provide those factors - concentration of productive forces can be directed unto themselves for them to be more efficient and efficacious. The result is that stuff gets not only cheaper to make, but also easier: a wider throughput is a good example of that. Less capacity is required to provide large amounts of supply. Expenditure becomes a much less reliable indicator in those circumstances without actual material numbers to be compared with.

as such, financial metrics that aim to provide a quality outlook have to be adjusted to actually account for that, which require a far more comprehensive analysis that considers supply, current production, capacity, etc. It's not merely about being cheaper, because those prices can be simply nominal for all intents and purposes (especially when there's central planning involved) and they can be way less. Then to gauge all of that into parity with some other economy? Depending on those structural differences, the numbers game can become ridiculous. What truly matters is the why of this type of analysis being done in the first place instead of a material comparison of productive forces.

I would wager good money the vast majority of the r+d is being handled by the chemistry and physics PhDs they churn out by the cartload. Where I personally see their top tier engineering brains working is in ship hull dynamics. Australia, Japan, South Korea, China and Iran are the people pushing forwards the development of frictional drag reduction on hulls. I haven't seen a single American paper on the topic despite it being one of the primary drivers for speed, noise and efficiency of ships.

The Canadian engineering experience was more like "everyone realizing a lot of high schools just did social passing/were grade inflating". Statics, physics, math, and circuits were the "our objective is to fail a third of the class minimum" classes

On the topic of boats FF I looked up the old naval engineering professors at my uni and her title is now something like:

Thread readers might remember Irving Shipbuilding as the company that doesn't want to keep skilled labour on because that's too expensive, tries to sue its own VP Engs when they leave if they're mean, can't actually build ships...

the Soviets signed the M-R Pact because Stalin was rebuffed by the Western Allies at every turn, and then signed their own deal-with-the-devil at Munich. As Zeppelin Insanity said, in some hypothetical where the West showed any kind of interest in working with the USSR, it's not unreasonable to assume that they would do so in a way that ends with the Soviets fighting Nazi Germany in 1939.

Czechoslovakia was partioned between Germany, Poland, Hungary and a newly formed Slovak Republic German vassal state.

At which point there is zero chance the war goes on as long as it did because the strategic depth of Poland + the SU means Germany is never going to be able to rotate its armies away from the East and mass enough troops in the West to launch Fall Gelb. Even Fall Weserebung becomes iffy. So either they go off half-cocked in the West and don't manage the strategic breakthrough near Sedan outmaneuvring the British and French, or they stay in a defensive posture with the token forces they had and concentrate on the East. Either way France doesn't get knocked out of the war and Britain remains on the continent, meaning Germany is just insanely outnumbered from the word go.

A significantly shorter war also means a lot of the Holocaust could have been prevented, as the industrial murder in the camps didn't get going until 1942, and the Holocaust by bullets required Germany occupying vast parts of Eastern Europe and the SU, which is also iffy without the minor Axis countries (Romania, Hungary, Italy) involved and with the pressure of a constant two front war. Even if they move up the timeline on the camps, they occupy significantly less territory and thus Jewish and Roma population.



Long story short, anyone blaming the Soviets for how WW2 went should cast at least three times as much blame on the Western Allies and also Poland.

https://www.npr.org/2024/05/02/1246636334/pentagon-military-healthcare

After downsizing health care for years, Pentagon says medical readiness was a casualty

quote:

...Now Rasmussen and other veteran medical officers warn that
U.S. military health care again needs a course correction. After a decade of downsizing, Defense Department officials also admit they need to rebuild the medical force and the general health of active duty troops. But restoring medical readiness to where it was during the last war, much less where is needs to be for the next one, is a by all accounts a herculean task.

[....]

Rasmussen deployed six times between 2005 and 2012. On his first tour to Iraq, he worked in tents and saw medics improvising — using cargo straps as tourniquets. On his last tour, in Afghanistan, he operated in a fully equipped hospital with new concrete floors and access to MRI and CT scans. Then the wars wound down. And Rasmussen felt some of the progress slide back.

"There were efforts to outsource ... beneficiary care from the military treatment facilities to civilian institutions, which emptied out and hollowed out storied military medical centers like Walter Reed," he says.

Even before the wars ended the Pentagon activated a plan to tame massive health care costs by pushing military medical care into the private sector, especially for family members.

The result was a sort of spiral. Military hospitals lost the minimum numbers of patients they needed to keep doctors in practice. The quality of military care suffered, and many clinicians left. Even more resigned during the pandemic, and Pentagon planners realized that the private health care sector they had hoped to lean on actually needed help itself, from the military. But the cuts kept going, says Rasmussen.

Pentagon officials even floated an idea to close the Uniform Services University, the military's medical school, which trains up military doctors and preserves medical advances, like those made during the wars in Iraq and Afghanistan. "I mean, why do we need a military medical academy?" Rasmussen jokes.

"They achieved the highest rate of survival from battlefield wounds in the history of warfare. They were able to save people that would have died in any prior conflict," says Dr. Art Kellerman, who served as dean of the Uniform Services University of the Health Sciences during the threats to shut it down.

Kellerman frames it as a national security priority. He says as much as a helmet or flak jacket, the success of U.S. military medicine gave troops confidence to rush into a firefight, knowing they would probably survive. U.S. allies joined the fight knowing a U.S. medevac would fly to the rescue within 30 minutes if they got blown up. What's more, Kellerman says, those in the fight believed they'd not just survive, but live well.

"They dramatically improved their ability to rehabilitate wounded warriors after being injured. And many of them were able to return to duty and others were able to return home to be with their families and to function for the rest of their careers. Some of them today are members of Congress," he says.

Kellerman says America needs that same ready medical force for any future conflict.

And the Pentagon now seems to agree.

A Defense Department internal memo obtained by NPR concluded that outsourcing didn't actually save money but did hurt readiness. The so-called "stabilization memo" directs the Pentagon to reverse course, to bring more medical care back to its hospitals on base and increase medical staff, both to keep America's standing army fit for duty and to make sure enough military doctors and nurses are trained up for a possible future war.

Military strategists caution that generals often try to refight their last war, but America's next war may be different. In Iraq and Afghanistan, the golden hour was possible because the U.S. had air superiority; the enemy had no planes or helicopters.

"Sooner or later, somewhere, we're not going to have air superiority. And I don't care if we think we are, we should plan for not having it,"
says Dr. Sean Murphy, who served 44 years and retired in 2021 as Air Force deputy surgeon general.

Murphy points to Ukraine, where two conventional armies suffer massive casualties being evacuated by ground.

Or even more extreme: a possible conflict with China around Taiwan.

"What we've realized when we start looking at a theater like the Pacific, and the distances and a peer-to-peer fight, there is no way we're going to get to the golden hour. So if we're not going to be able to get a surgeon or somebody to the golden hour, then what we have to do is ... to make everybody a medic," he says.

To do that he says, the Pentagon needs, urgently, to build back its ready medical force.

"The most important fighting system we have is the human system. It's not a plane or a ship or a tank," says Rasmussen. He says he saw that again and again when he served.

"And that human system is only optimized and cared for if there is a robust and expert military health system," he says. "I think degrading that risks our national security."

how it really works is that when you first pick a door you have a 1/3 chance of being right and a 2/3 chance of being wrong, and then monty hall has to open a door with a goat behind it

this means that if you picked a door with a goat behind it then monty has no choice but to open the other door with a goat behind it, which means that in the 2/3 of cases where you picked wrong switching doors will guarantee that you get the car

Exclusive: Russian troops enter base housing US military in Niger, US official says

quote:

WASHINGTON, May 2 (Reuters) - Russian military personnel have entered an air base in Niger that is hosting U.S. troops, a senior U.S. defense official told Reuters, a move that follows a decision by Niger's junta to expel U.S. forces from the country.

The military officers ruling the West African nation have told the U.S. to withdraw its nearly 1,000 military personnel from the country, which until a coup last year had been a key partner for Washington's fight against insurgents who have killed thousands of people and displaced millions more.

A senior U.S. defense official, speaking on condition of anonymity, said Russian forces were not mingling with U.S. troops but were using a separate hanger at Airbase 101, which is next to Diori Hamani International Airport in Niamey, Niger's capital.

US forces now (unwilling) sharing the base with Russians.
