Good news for (some) soldiers

David Pugliese reports on the US Army’s work on a new, significantly lighter, Squad Automatic Weapon:

“We are using cased telescoped ammunition which uses a strong plastic case instead of a traditional brass case,” said Kori Phillips, a systems management engineer with ARDEC.

Weight reduction for the weapon was achieved by designing the new weapon platform using the latest materials technologies as well as modeling and simulation to achieve minimal weight without compromising performance.

With a basic load of 1,000 rounds, the LSAT light machine gun and its cased telescoped ammunition is 20.4 pounds lighter than a traditional SAW with the same amount of standard, brass-cased ammunition.

[. . .]

“The cased telescoped ammo still provides the same muzzle velocity, range and accuracy as the brass-cased ammo,” Phillips said. “We’re not sacrificing lethality for weight. The plastic case does the same job.”

In addition to significant weight savings, the LSAT is designed to provide other advantages over the current SAW. With a rotating chamber design, the cased telescoped light machine gun improves reliability.

“We’ve avoided the common problem of failure to feed and failure to eject,” Phillips said. “In the current SAW system, that’s one of the places where you primarily have failures and malfunctions.”

Of course, if the new ammunition works well for the SAW, it’ll certainly be adapted for other small arms (in a hot combat zone, you never have “too much” ammunition available, but you often have “too little”).

Logic puzzle

Tim Harford has been retweeting this little puzzle as part of a discussion with @paullewismoney:

Reminds me of an old riddle, Paul. Which weighs more, a pound of gold or a pound of feathers? You will know the answer…

Thanks all tweets re: @paullewismoney and whether a pound of gold weighs more than a pound of feathers. Most of you are wrong…

…but @adam_j666 @andrew_F_smith and @cleverwithmoney have it right. Congrats. And I’m sure @paullewismoney had it right.

It won’t hurt just the “rich”

Michael Boskin illustrates just what the current levels of US government spending will mean when translated into personal tax rates:

Many Democrats demand no changes to Social Security and Medicare spending. But these programs are projected to run ever-growing deficits totaling tens of trillions of dollars in coming decades, primarily from rising real benefits per beneficiary. To cover these projected deficits would require continually higher income and payroll taxes for Social Security and Medicare on all taxpayers that would drive the combined marginal tax rate on labor income to more than 70% by 2035 and 80% by 2050. And that’s before accounting for the Laffer effect, likely future interest costs, state deficits and the rising ratio of voters receiving government payments to those paying income taxes.

It would be a huge mistake to imagine that the cumulative, cascading burden of many tax rates on the same income will leave the middle class untouched. Take a teacher in California earning $60,000. A current federal rate of 25%, a 9.5% California rate, and 15.3% payroll tax yield a combined income tax rate of 45%. The income tax increases to cover the CBO’s projected federal deficit in 2016 raises that to 52%. Covering future Social Security and Medicare deficits brings the combined marginal tax rate on that middle-income taxpayer to an astounding 71%. That teacher working a summer job would keep just 29% of her wages. At the margin, virtually everyone would be working primarily for the government, reduced to a minority partner in their own labor.

Nobody — rich, middle-income or poor — can afford to have the economy so burdened. Higher tax rates are the major reason why European per-capita income, according to the Organization for Economic Cooperation and Development, is about 30% lower than in the United States — a permanent difference many times the temporary decline in the recent recession and anemic recovery.

While policy makers may shrug off the impact of higher tax rates, it has a significant effect on individual choices when it comes to part-time jobs, overtime, and even raises. Even if in reality working a few hours of overtime won’t make a difference, psychologically, the higher tax burden can act as a deterrent: “why put in the effort if the government gets more out of my effort than I do?”

“We used to talk to career criminals all the time. They were our sources”

A look inside the News of the World newsroom before the closure:

“It was the kind of place you get out of and you never want to go back again.” That’s how one former reporter describes the News of the World newsroom under editor Rebekah Brooks, the ferociously ambitious titian-haired executive who ran Britain’s top-selling Sunday tabloid from 2000 to 2003.

Journalists who worked there in that period describe an industrialized operation of dubious information-gathering, reporters under intense pressure attempting to land exclusive stories by whatever means necessary, and a culture of fear, cynicism, gallows humor and fierce internal competition.

“We used to talk to career criminals all the time. They were our sources,” says another former reporter from the paper who also worked for Murdoch’s daily tabloid, the Sun. “It was a macho thing: ‘My contact is scummier than your contact.’ It was a case of: ‘Mine’s a murderer!’ On the plus side, we always had a resident pet nutter around in case anything went wrong.”

Moral outrage is a bad source of legislative impetus

Filed under: Law, Media, USA — Tags: , , — Nicholas @ 09:53

Steve Chapman attempts to explain why the multiple “Caylee’s Law” proposals in many state legislatures are uniformly bad ideas that will become bad laws:

It was once suggested, as a general rule of staying alive, never to fly on an airline named after a state or the owner. As a general rule of sound government, it’s also a good idea never to enact a law named after a person. Personalizing criminal law usually stems from fruitless outrage at a freakish event.

Plenty of legislators are ignoring that risk. Their proposals, all going by the name “Caylee’s Law,” are an understandable response to the acquittal of Casey Anthony of killing her 2-year-old daughter. Swearing when you stub your toe is also understandable, which doesn’t mean it will do your toe the slightest good.

[. . .]

Targeting parents who fail to report missing kids on a government-approved schedule will probably accomplish nothing useful. Conscientious adults with grounds for concern already call the cops. But the change would burden police with trivial cases that would soon resolve themselves.

Already kids are reported missing at the rate of more than half a million a year, usually because they run away or neglect to tell parents where they are. A 2002 Justice Department study noted that “all but a very small percentage are recovered fairly quickly.”

But a mother whose son has a habit of absconding and reappearing could go to prison for exercising sensible patience. A divorced dad whose ex-wife gets angry when he’s tardy returning the kids from a weekend outing could give new meaning to “custodial parent.”

Soviet tank battles

I just picked up a copy of The Battle of Kursk by David M. Glantz and Jonathan M. House, based on a recommendation by Jim Dunnigan in his World War II Bookshelf. While any attempt to pick the top books about the Second World War is doomed to perpetual nit-picking by second-guessers and Monday Morning Quarterbacks, I’ve generally found the works he recommended to be worth reading.

Although I’ve read much about World War II, I haven’t read much about arguably the most critical part of the entire war: the gargantuan battles pitting the Soviet Red Army against Hitler’s Wehrmacht. Some of that is just sheer pig-headedness: I used to work for the biggest wargame store in Toronto, back when wargames meant cardboard counters, vast paper hexagonal maps, and charts and tables galore. The hardest of the hard-core gamers seemed to be either Napoleonic grognards (down to the secret stash of sabres and shakos in the gaming room) or even more dedicated junkies of the “Great Patriotic War”/”Operation Barbarossa”. Some of the latter were genuinely crazy, right down to the barely contained hints that “Hitler was just misunderstood”.

On the assumption that certain forms of craziness are contagious, I avoided most of the latter as much as I could, consistent with my duty to sell them the latest and greatest game involving their particular passion.

One day, perhaps in a fit of weakness, I allowed myself to get lectured by one of the fanatics about the details of the Battle of Kursk. The fan who felt the need to bend my ear was eager to impart information about some “famous battle” that turned out to have been a serious tactical miscalculation by a Soviet officer. The story, as he told it, had a very large formation of Soviet tanks “taking a shortcut” through a major minefield, resulting in many disabled/destroyed tanks and wounded or dead men. In the telling, this kind of thing could not be admitted as having happened without some enemy contact, so it was propagandized as being a major tank battle involving significant formations of German panzer troops and/or SS units (of whom, of course, the glorious defenders of the Motherland took a greater toll than they suffered themselves).

I’d heard a couple of variations of this story by this point, but none of them could name the general who led the formation, the location of the event, or the “battle” that was supposedly re-written for propaganda purposes.

Does this story ring a bell for anyone? I’d imagine if it had really happened in a way close to the way it was told to me, it would have been documented in great detail (especially after the fall of the Soviet Union, in that brief period that both the Soviet and the Nazi records were available to western researchers without direct censorship).
