Army shows more than one way to look under a car

Manning security checkpoints is hazardous duty, but vehicles still must be checked. So the U.S. Army is helping develop products that will allow soldiers to do their job, preferably from a distance.

Researchers and scientists at the U.S. Army Tank Automotive Research, Development and Engineering Center (aka TARDEC) have focused on semi-autonomous robotic systems capable of remotely inspecting a vehicle's undercarriage for explosives or roam the line looking for suspicious activity.

TARDEC will showcase a couple of its favorite autonomous robotic systems this week at the Michigan Security Network Market Leadership Conference. Both units were developed for … Read more

Defense Department issues new open-source guidance

The U.S. military is no laggard when it comes to open-source software adoption, but apparently thinks it can do better. The U.S. Department of Defense on Tuesday issued new guidelines designed to remove roadblocks to open-source adoption, arguing that open source can help the Defense Department "anticipate new threats and respond to continuously changing requirements."

And to think open-source software like Linux used to be considered a threat to secure Defense Department systems.

While Department of Defense CIO David Wennergren's revised guidance (PDF) is not intended to create new policy, it does provide clarity that … Read more

Defense Department to partially lift flash drive ban

The U.S. Department of Defense ban on USB thumb drives instated nearly a year ago will eventually be partially lifted to allow authorized people to use official flash drives for mission-critical functions, according to a top military official.

"In the future, we expect that a government-owned and procured USB flash media, that is uniquely and electronically identifiable for use in support of mission-essential functions on DoD networks, will be permitted for use by authorized individuals," Robert Carey, chief information officer for the Department of the Navy, wrote in his blog recently.

"We are working on upgraded … Read more

Firing up the newest Tasers

DUBLIN, Calif.--Don't tase me, bro. Really.

CNET News took a trip to the Alameda County Sheriff's Office Regional Training Center on Friday to have a look at some of the newest equipment from Taser, which was among the companies showing off weaponry at the UrbanShield 2009 training event. The electric-shock gadgets are controversial and have drummed up some bad press over the years for causing the occasional serious injury or even fatality. But the company has maintained its insistence that they are significantly safer than the alternative (i.e. guns).

We didn't get to tase anybody. … Read more

Five awesome iPhone tower defense games

If there's a bigger game genre for the iPhone than Tower Defense clones, I haven't found it. A quick search of the App Store reveals well over 100 titles matching that description.

No surprise there: the iPhone's touch screen lends itself perfectly to this kind of game (which, for the uninitiated, requires strategic placement of defensive armaments to ward off increasingly powerful attackers).

OK, but which TD titles are worth your time--and cash? Here's a roundup of my five favorites. It's by no means a definitive list, but I think fans of the genre will enjoy them all.

Bloons Tower Defense Balloons. Monkeys. Darts. Nearly everything from the beloved Web-based classic appears in the iPhone version. The controls are a little finicky, but if you want to introduce young kids to the world of tower defense, this $2.99 game is the one to get. Navy Patrol: Coastal Defense Though the learning curve is a bit steep and the onscreen action can get a little cluttered, this naval-themed, open-path TD exercise offers some of the most in-depth and challenging gameplay I've found. And the $1.99 purchase price includes new maps as they get added to the game.… Read more

Defend Mars from attack

Sentinel: Mars Defense is a visually rich, science-fiction-flavored, fixed-path tower-defense game, the less interesting--but also less expensive--predecessor to Sentinel 2: Earth Defense. You command the dropship Sentinel, tasked with defending a colony on Mars from seemingly endless waves of remorseless aliens.

Following a traditional fixed-path format, aliens advance up a single (sometimes forking) route, as you use your limited resources to marshal an array of upgradeable towers to stop them across four different maps, making strategic decisions on which towers to buy, where to place them on a grid, and whether to sell or upgrade units. The enemies are largely … Read more

Pentagon ships new M-ATVs to Afghanistan

U.S. troops in Afghanistan are now starting to receive the first of thousands of a new vehicle intended for treacherous mountain roads and tight urban lanes.

The Defense Department said Wednesday that it had loaded seven M-ATVs (for "mine-resistant, ambush-protected all-terrain vehicles") onto a pair of aircraft for deployment to Afghanistan. Over the course of the next year, the military expects to field more than 6,600 of the vehicles (Click for a PDF of the M-ATV's brochure).

The M-ATV fits into a middle ground between up-armored Humvees, which it will be replacing in Afghanistan, and … Read more

Defend the dungeon against greedy adventurers!

Dungeon Defense is a promising game with ample swords-and-sorcery ambiance and an innovative take on the traditional tower-defense format. You have to protect a dangerous dungeon, commanding an evil army of skeletons as it fights off heroic (or maybe just greedy?) adventurer types. But the "towers" in this tower-defense game are your skeleton warriors, and the skeletons--being skeletons--they move.

The interface mimics many other tower-defense games: you pick from three skeleton types (light, heavy, and archer), you choose where you want to place them on certain locations on the map, and then you can sell, upgrade, and heal … Read more

Missile-tracking satellites launched on demo flight

A United Launch Alliance Delta 2 rocket roared to life and thundered away from the Cape Canaveral Air Force Station Friday, successfully boosting a pair of experimental missile-tracking satellites into orbit for the U.S. Missile Defense Agency.

With its roots in the old "Star Wars" program, the goal of the $1.5 billion Space Tracking and Surveillance System mission is to demonstrate the ability to detect and track enemy missiles from launch, through the so-called mid-course phase of flight to atmospheric entry, providing more accurate targeting data for interceptors.

"The purpose of these satellites is to … Read more
