This is my boom stick. Well, not mine, but General Atomics'. Known primarily for manufacturing the Predator drone, General Atomics has also moved into the weapons business, as demonstrated by this first ever successful test of their "Blitzer" rail gun.

Despite the vehicles' armor, rocket-propelled grenades (RPGs) can still take out Humvees and MRAP vehicles with ease. But a company wants to change that equation with airbags that neutralize incoming RPGs and prevent them from exploding.

It's often said that a soldier's greatest weapon is his head; now, the U.S. Army plans to sharpen that weapon, installing radar in troops' combat helmets, upgrading one of the oldest pieces of infantry armor into an effective tactical device.

The Helmet Mounted Radar Program aims to provide a near-360-degree field for Moving Target Indicator (MTI) radar sensors that is low-power and can detect a moving threat as far out as 25 meters. The sensor should be integrated into the combat helmet and weigh less than two-and-a-half pounds, with less than a pound mounted on the helmet itself.

Emergency medical care for soldiers wounded on the battlefield has come a long way since Hawkeye and Hot Lips. But for Special Forces troopers operating deep behind enemy lines, that care often remains out of reach. Blood loss in particular makes seconds count, and imperils commandos operating far away from friendly bases.

To help with the problem of blood loss from traumatic wounds, the military has started field-testing a device more Mandalorian than M.A.S.H.: a plasma knife.

Like most Army commanders, Lt. General Rick Lynch says that he needed more troops in Iraq, and that they would have saved the lives of men lost under his command. Unlike most commanders though, Lynch isn't demanding flesh and blood soldiers, but steel and rubber robotic infantrymen.

Blimps first soared above battlefields in 1794 to spy on Austrian and Dutch troops. Now the U.S. Army wants them as radar platforms for defense against cruise missiles. A Raytheon-designed blimp made its first flight yesterday at Elizabeth City, North Carolina.

Going green makes military sense to the U.S. Army. Self-sufficient vehicles and base camps require fewer supply convoy runs that stretch logistics lines thin across hostile territory. The Army's new "zero-footprint" concept for a camp includes a package of very cool technologies.

Soldiers could eventually obtain their drinking water from vehicle exhaust, based on water-purification technologies being developed by the U.S. Army's TARDEC and DARPA labs. Garbage and waste produced by camps could also become new sources of energy.

Each equipped with $48,000 worth of GPS components, electronic maps, and wearable computers, troops of the Army's 5th Brigade, 2nd Infantry Division are heading to Afghanistan as part of the resurrected Land Warrior program. The Army is hoping the revised, eight-pound set of gear will be more beneficial than when the $500 million program was canceled in 2006.
