US deploys 'game-changer' weapon to Afghanistan

WASHINGTON (AFP) – It looks and acts like something best left in the hands of Sylvester Stallone's "Rambo," but this latest dream weapon is real -- and the US Army sees it becoming the Taliban's worst nightmare.
The Pentagon has rolled out prototypes of its first-ever programmable "smart" grenade launcher, a shoulder-fired weapon that uses microchipped ammunition to target and kill the enemy, even when the enemy is hidden behind walls or other cover.

After years of development, the XM25 Counter Defilade Target Engagement System, about the size of a regular rifle, has now been deployed to US units on the battlefields of Afghanistan, where the Army expects it to be a "game-changer" in its counterinsurgency operations. "For well over a week, it's been actively on patrols, and in various combat outposts in areas that are hot," said Lieutenant Colonel Chris Lehner, program manager for the XM25.
The gun's stats are formidable: it fires 25mm air-bursting shells up to 2,300 feet (700 meters), well past the range of most rifles used by today's soldiers, and programs them to explode at a precise distance, allowing troops to neutralize insurgents hiding behind walls, rocks or trenches or inside buildings.

"This is the first time we're putting smart technology into the hands of the individual soldier," Lehner told AFP in a telephone interview.
"It's giving them the edge," he said, in the harsh Afghan landscape where Islamist extremists have vexed US troops using centuries-old techniques of popping up from behind cover to engage.
"You get behind something when someone is shooting at you, and that sort of cover has protected people for thousands of years," Lehner said.
"Now we're taking that away from the enemy forever."
PEO Soldier says studies show the XM25 is 300 percent more effective than current weapons at the squad level.
The revolutionary advance involves an array of sights, sensors and lasers that reads the distance to the target, assesses elements such as air pressure, temperature, and ballistics and then sends that data to the microchip embedded in the XM25 shell before it is launched.
Previous grenade launchers needed to arc their shells over cover and land near the target to be effective.

"It takes out a lot of the variables that soldiers have to contemplate and even guess at," Lehner said.
If, for example, an enemy combatant pops up from behind a wall to fire at US troops and then ducks behind it, an XM25 gunner can aim the laser range finder at the top of the wall, then program the shell to detonate one meter beyond it, showering lethal fragmentation where the insurgent is seeking cover.
Use of the XM25 can slash civilian deaths and damage, the Army argues, because its pinpointed firepower offers far less risk than larger mortars or air strikes.
The result, the Army says, is "very limited collateral damage."
The Pentagon plans to purchase at least 12,500 of the guns -- at a price tag of 25,000 to 30,000 dollars each -- beginning next year, enough for one in each Infantry squad and Special Forces team.
Lehner said the XM25 was special in that it requires comparatively little training, because the high-powered technology does so much of the work.
"This system is turning soldiers with average shooting skills into those with phenomenal shooting skills," he said.

What If Hugh Jackman Had Been Jack Sparrow?

We're trying to picture him with a bandanna. Michael Loccisano/Getty Images for Worldwide Orphans Foundation There was a time when Johnny Depp wasn't a superstar. He's been a star and a respected actor for quite some time, but it wasn't until he donned a bandanna and put on eyeliner to play the colorful Captain Jack Sparrow in "Pirates of the Caribbean: The Curse of the Black Pearl" in 2003 that he graduated to the level of a Will Smith or Tom Cruise. Well, it turns out that if things had worked out differently, Depp would never have gotten the opportunity. If one of the film's writers had had his way, the part would have gone to Hugh Jackman.

Speaking at the Advance Lounge Chair series this week, Stuart Beattie (who is credited as one of the "Story By" writers for "Black Pearl") said, "I initially wrote that character with Hugh Jackman in mind." Just how committed was he to the idea of casting Jackman? He named the character Jack in his honor. But according to Beattie, Disney didn't think Jackman was a big enough star, eventually going with Depp, who at the point had only had one $100 million movie to his credit: "Sleepy Hollow."

Whenever a film becomes enormously successful and launches a lucrative franchise, there will be that inevitable moment down the road when we learn who was originally meant to play the characters we've come to know and love. (Honestly, how many paragraphs into Tom Selleck's obituary will it take before they mention that he was almost Indiana Jones?) Usually, people tend to favor the actor who ended up getting the part because that person is so ingrained in our consciousness as that character. But in the case of Jackman, we actually think it could have worked with him in the role. As he's demonstrated in the "X-Men" series, he has the right combination of brawn, swagger and humor that would have served him well as Captain Jack.
But whereas in earlier cases of an actor getting passed over for a big role -- like Eric Stoltz in "Back to the Future" -- we don't need to feel sad for Jackman or lament the glorious career he could have had. Jackman's doing just fine: He's busy currently working on "Wolverine" with "Black Swan" director Darren Aronofsky and is a Tony-winning Broadway actor. (Ironically, one of his biggest duds was "Australia," which was co-written by Beattie.)

As for Depp, Captain Jack will probably end up being his signature role, for better or worse. Genuinely funny and compellingly larger-than-life in a way that movie stars rarely are anymore in blockbuster films, Depp helped make the first "Pirates of the Caribbean" as supremely entertaining as it was. (Amazingly, it was that role that finally earned him his first Oscar nomination after a decade of underappreciated work in everything from "Ed Wood" to "Donnie Brasco." Not bad for a performance that Depp recently said the Disney bigwigs initially hated, insisting he was "ruining the movie.") At a time when most A-list stars weren't actually great actors, it was really satisfying to see Johnny Depp become part of Hollywood's upper echelon. Sadly, the subsequent "Pirates" sequels got progressively lamer, and Depp's hammy shtick grew tiresome. In the end, though, both actors arrived at the same place: Depp will forever be linked with Captain Jack, and Jackman shall always be Wolverine. It's the trade-off you have to make to become a superstar. And, really, isn't that better than ending up a cinematic footnote like Tom Selleck?
