From the Danger Room:
Grappling hooks attached to siphon electricity from low-hanging power lines. Computers mounted onto a commando’s chest plate. Communications gadgets small enough to fit into gear pouches worn around the waist. The Air Force is actually preparing its special operators to act (and outfit themselves) more like the Batman.

My Comment: What I find interesting (and amusing) about the Air Force logo, is that it looks very similar to the logo from Russia's GRU (military intelligence).

Top 10 Animal Recruits in War
From Live Science:
Humans have enlisted animals to help fight their battles since the dawn of war, and today's militaries use an even wider range of creatures for everything from bomb sniffing to coastline patrolling.
That may seem remarkable, considering that dogs, horses and other animals certainly did not evolve for the purpose of human conflict. Yet nature's designs have not only stood the test of time, but have also inspired human engineers to try to harness their power directly or through mechanical imitations.
Here we count down some of the creatures that have become unwitting recruits in both ancient and modern warfare.

A New IED Killer
'Blade' Of Water That Can Cut Through Steel To Be Used In Afghanistan To Destroy IEDs -- The Daily Mail
A device that shoots a blade of water capable of penetrating steel is to be used in Afghanistan to help soldiers disable improvised explosive devices, or IEDs.
The Stingray was developed by Sandia National Laboratories and 3,000 of the gadgets are heading out to U.S. soldiers in the region this year.
Stingrays are filled with water and an explosive material that - when detonated - creates a shockwave that travels through the water and speeds it up, creating a thin, powerful blade of water capable of penetrating steel.

Gadgets Give Soldiers In Afghanistan A Slice Of Home -- The Danger Room
The heat and the dust and the diesel fumes. The constant drone of the generators, of vehicles, of radio static. The same food everyday, the same meal in the same brown plastic bag. The constant danger and uncertainty. The confusion, wonder and consequences waiting for you outside the wire.

My Comment: I own a small and isolated chalet that is in the bush and north of Montreal. On weekdays, everyone leaves and the closest person is a few kilometers away. I never feel alone .... my gadgets, internet, and satellite TV gives me an environment that tells me that I am in civilization, and everyone that I know is only a short distance away.
Nothing can be further from the truth .... but it is an illusion that you only become sensitive to when you think about it. For the soldiers in Afghanistan they are probably in the same type of environment .... but when they go outside the wire .... a very different reality sets in.

US Navy Seeks 'Safer' Bomb
From New Scientist:
COULD a variable-yield bomb reduce the number of innocent people killed or injured during an air attack targeting enemy soldiers? That's the thinking behind a US navy plan to develop a "dial-a-blast" bomb.
The navy is seeking proposals from companies to create a bomb weighing 200 kilograms that can either be detonated at full or reduced power. The idea is that the device could be loaded onto planes before a target has been identified, and the explosive power set by the pilot once a target is known. If there is a risk of killing civilians, then the explosive power can be reduced to ensure a small blast radius. In an unpopulated area the bomb, currently known as the Selectable Output Weapon, could be set so that it has the same power as a regular bomb of the same size. Carrying a single bomb would make it easier and cheaper for the navy to arm its planes.

The U.S. Sniper's More Accurate, Quieter Rifle -- Popular Mechanics
Army Snipers in Afghanistan will receive an improved rifle this fall.
For snipers, every war is different. Recognizing the differences between conditions in Iraq and Afghanistan, the Army is now selecting a contractor to upgrade the 22-year-old Remington bolt-action rifle to become a more effective killing machine. The Army will pour about $5.6 million into upgrades to the M24, with the new gear expected to be delivered to troops by this fall. The M24's barrel is being modified to shoot heavier .300 Winchester Magnum rounds, instead of the 7.62mm NATO ammunition, which should extend the rifle's maximum effective range by hundreds of yards to a maximum of about 1400 yards. The suppressor will reduce the noise and flash of the gun so snipers can stay in their hiding positions much longer after they fire.

The Future Of Body Armor
Although it will be some time before the new germanium-based fabric has the same stopping power as this bulletproof vest, scientists are now exploring the possibility of using it to harness solar power. iStockphoto
'Tissue Paper' Could Stop Bullets, Harness Solar Energy -- Discovery News
Who wouldn't want a shirt that could stop a bullet and power your iPod? A new fabric can do just that.
A soft "tissue paper" made from normally brittle germanium and silicon contains individual fibers as strong as bulletproof Kevlar. Woven into traditional fabric or embedded in hard plastics, the new nanowires could stop bullets, harvest solar energy or perform dozens of other tasks.

The Army Wants To Smell Your Fear
Smelling Threats from a Distance Using people's unique scents to identify them before they get too close to troops could save soldiers' lives.
The Army Wants Olfactory Sensors That Can Smell Potential Perps At A Distance -- Popular Science
If something doesn’t smell right, the Army wants to know about it. But while the Pentagon has been angling for a biosensors that can smell fear or nervousness in a person’s bodily emanations for some years now, the Army wants something more: The ability to “uniquely identify an individual based on scent” from a distance or even days after the person has left the scene.

A Counter Argument That Our Obesity Epidemic Is Not A Threat To National Security
From Slate:
The obesity epidemic has nothing to do with national security.
"My name's Dewey Oxberger; my friends call me 'Ox'. You might've noticed I've got a slight weight problem," said John Candy to his fellow Army recruits in the 1981 film Stripes. "So I figured while I'm here, I'll lose a few pounds. I'm gonna walk out of here a lean, mean fightin' machine!"
In real life, the 6-foot-2, 300-pound Ox wouldn't have made it through the barracks door. The movie's release coincided with a new weight-control program in the U.S. military. Recruits were already screened for height and weight; now they'd be checked for body fat percentage, too. It's been 30 years since Stripes came out, and the rate of obesity among adults has doubled. A report out this week estimates that 27 percent of all Americans of recruitment age—that's 9 million young adults—are too fat to fight for their country. At a press conference Tuesday, Sen. Richard Lugar, Agriculture Secretary Tom Vilsack, and a group of retired generals and admirals warned that our poor diets and lack of exercise have now become a danger to homeland security.

Navy SEALs Recognize Anger More Quickly
From Live Science:
The brains of elite soldiers can respond faster to signs of anger than normal, which could help them detect threats and make the difference between life and death when under fire.
The differences in the brains of those who excel in extreme circumstances are poorly understood. Such research might help improve military performance, explained neuroscientist Alan Simmons at the University of California at San Diego.

Better Military Technology Does Not Lead to Shorter Wars, Analysis Reveals
From Science Daily:
ScienceDaily (Mar. 31, 2010) — It is generally assumed that military technology that is offensive rather than defensive in nature leads to shorter wars. Yet, a new doctoral thesis from the University of Gothenburg, Sweden, shows that this assumption is not correct.
For long, researchers have thought that offensive military technology, such as armoured cars and attack jets, makes it easier to shorten the duration of a war. It is also generally perceived that when the offensive technology is more effective than the defensive technology, it is more advantageous to start a war.

Mobile Nuclear Reactors Could Provide Power And Jet Fuel For Military, DARPA Says
Navy Aircraft Could nuclear-powered carriers use their reactors and seawater to provide jet fuel for their aircraft? U.S. Navy/Stephen Rowe
From Popular Science:
Making U.S. Navy carrier groups and Army bases more self-sufficient and energy-efficient could mean turning to mobile nuclear reactors. The Pentagon's DARPA scientists have put forth the modest proposal of deploying miniature reactors to convert hydrogen and carbon into military jet fuel, as well as providing power, The Register reports.

Oceanology: Tethered Antenna Keeps Subs In Touch
From New Scientist:
ROBOTIC submarines have always had trouble when it comes to picking up GPS signals and communicating with their operators. That's because radio signals do not travel far underwater. If the submarines do not surface regularly in order to check their position, they run the risk of drifting off-course.
This problem could now be solved, thanks to a wing-like antenna that piggybacks on small submarines. The antenna ascends to the surface on a tether as and when needed, enabling satellite communications, including GPS readings. It can even carry a camera to serve as a kind of periscope for the sub's controller.

Assault Breacher Vehicles Beat Bombs In Afghanistan
From Popular Mechanics:
Marine corps engineers in Afghanistan have a new beast of a vehicle to help them defeat explosive booby traps.
The civilian mechanics at Anniston Army Depot in Alabama usually only fix vehicles for the Army, not design them for the Marine Corps. But as Marines push into contested areas of Afghanistan, their engineers face a persistent threat from roadside bombs. The mechanics at Anniston saw they could build a safe ride for these military engineers by adding off-the-shelf equipment to an M1A1 Abrams battle tank. The result, called the Assault Breacher Vehicle (ABV), maximizes the depot staff’s experience at fixing the M1A1 and their ability to mount heavy engineering equipment, including a 12-foot plough, onto its hull. The Army donated excess tank parts from its inventory to create the ABV.

US Marines Embrace Web 2.0
In About-Face, Marines Embrace Web 2.0 -- The Danger Room
Last summer, the U.S. Marine Corps took a draconian approach to Web 2.0, issuing a sweeping ban on Twitter, Facebook, MySpace and other social media sites from its networks.
In an order issued yesterday, the service changed course, issuing guidelines to encourage “responsible and effective use” of social networking technology. “The Marine Corps embraces and strives to leverage the advances of internet-based capabilities,” the directive states. “Effective immediately, internet-based capabilities will be made available to all MCEN [Marine Corps Enterprise Network] users.”

Spy In The Sky That Sees Round Corners
From New Scientist:
WHY jump in a cab to "follow that car" when an airborne drone could do the job for you? The US Pentagon's Defense Advanced Research Projects Agency is developing a radar system which sees around corners and down into "urban canyons". DARPA hopes to be able to track vehicles across an entire city using just a few uncrewed aircraft.

Say Hello To The Astute, The Best Submarine In The World
Astute sits on the shiplift outside the Devonshire Dock Hall in Barrow-in-Furness, ready to be lowered into the dock. The three starboard torpedo tubes are visible on the front of the submarine
Defender Of The Realm: Britain's £1.2bn Submarine - And Typically, We Can't Afford It... -- The Daily Mail
This is the best submarine in the world. It is virtually undetectable, has reinvented the periscope and sonar, and doubles as a floating GCHQ. It also happens to be British. Its only weakness? At £1.2bn, we can't actually afford it
She could prowl the depths of the oceans without stopping for her entire 25-year lifespan, her sleek curves undetected. She generates her own oxygen and fresh water from the surrounding sea, never has to refuel and never needs to break the surface. Indeed, the only reasons for her to come up after 90 days on patrol are to restock with food and to help preserve the sanity of her crew.

My Comment: The Royal Navy ruled the oceans for a reason .... they developed and manufactured great ships and trained even better sailors. But in today's world money is more important than technology, well trained personnel, and having the best boat.

What's The Point Of Nuclear Weapons On Instant Alert?
From New Scientist:
IN THE next few weeks, President Barack Obama will publish his delayed Nuclear Posture Review (NPR), setting out the role nuclear weapons play in US defence. This is Obama's opportunity to end one of the most dangerous legacies of the cold war: the nuclear missiles the US and Russia keep ready to fly in minutes. The signs are that he is unlikely to take it.
This leaves the questions why does the US keep its nuclear weapons "on alert", and are they really needed?

NASA And U.S. Navy Pledge To Save Silicon Valley's Massive Airship Hangar
Hangar One An old airship home needs a reskin U.S. Navy
From Popular Science:
The landmark Hangar One needs a giant new Teflon skin to replace its toxic siding, but funding is an issue.
Hangar One's behemoth structure once housed airships such as the doomed U.S.S. Macon, and is so large that clouds can supposedly form and rain inside it. Now NASA and the U.S. Navy have promised to replace the hangar's toxic siding with a new Teflon-covered fiberglass fabric skin, The Register reports.
