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.

Speaking at the Association for Unmanned Vehicle Systems International conference, Lynch said that robot systems already in place could have saved 122 of the 155 men who died during his time in Iraq.

In a recent test at the White Sands Missile Range, a specially equipped C-130 plane fried a parked truck with a powerful laser. And while we still haven't seen evidence of the laser "defeating" a ground target, as Boeing puts it, a video of it scorching a direct hit on the hood of a truck is still pretty amazing.

At the first Robotics Rodeo, hosted this week by the U.S. Army and the Fort Hood III Corps in Texas, war machines replaced bulls and horses. Soldiers and civilian contractors used the opportunity, starting on Wednesday, to inspect a lineup of robots that could potentially find a place on the battlefield.

We at PopSci appreciate new weapons. And lasers. And laser weapons. Which is why we're excited to tell you that the Navy and the Marines have given a company called Applied Electronics about a million dollars to attach lasers onto planes. The weapons would be ultra-short-pulse (USP) lasers, which shoot beams of frequent-pulse light that create a path through the air, via which bolts of electricity can travel toward a target.

Taser has been breathlessly fanning the hype flames for their newest "less lethal" weapon, the X3. Now, they've sent us the first video of it in action, striking three unlucky Taser staffers who (I can only assume) volunteered for the inglorious task of being guinea pigs.

Thinking of going for a swim? Keep an eye out for the Reusable Unambiguous Swimmer Warning Vehicle, a torpedo that can hunt down any swimmer who poses a threat to U.S. waters. It circles around its victim, relays the exact GPS coordinates of the prey, and sounds an alarm.

The Army wants to modernize -- and Defense Secretary Robert Gates isn't sure he wants to pay. Among the budget cuts he announced yesterday was a major hit to the Army's most ambitious new weapons program, Future Combat Systems (FCS). Under Gates's proposed budget, a set of FCS fighting vehicles that was supposed to provided light-brigade speed with heavy-brigade punch will be axed entirely. And you know what? Maybe that's okay. The core of what makes FCS futuristic is its ambitious wireless network, which will connect soldiers, surveillance drones and sensors, giving everyone more and better information than ever before.

Author James Vlahos explains how it's all supposed to work in this article, from our May issue.

Wall-E went to Iraq.

The small robot rolled out of the desert scrub into a village, paused between two houses, and then approached the closer one. His square head swiveled around, unblinking camera eyes surveying the structure. The sound of shuffling boots filled the air as six U.S. Army soldiers rushed in behind him, assault rifles drawn. Reaching the building he'd scoped, they took cover inside. The robot, meanwhile, whirred on tank treads to investigate the second house. The building had no door, and he rolled inside easily. The soldiers followed. Bang, bang! Gunfire erupted, and moments later the Americans emerged unscathed. The two insurgents inside the house weren't as lucky.

PackBots roam the streets of Iraq defusing bombs. Remote-controlled SWORDS robots shoot rifles and rocket launchers with deadly accuracy. Predator drones piloted by soldiers in Nevada drop missiles on Iraq and Afghanistan. The Wasp robot flies over neighborhoods full of insurgents, recording what's below with a camera as small as a peanut.

If this sounds like a futuristic science fiction story, it's not. As of today, over 12,000 robots are working in Iraq, up from zero five years ago.

Truck-mounted IED-destroying lasers have already been tested in Iraq, but firing lasers from an airplane is a more difficult proposition. The first successful test of a plane-mounted laser gun came on August 7, when Boeing’s 18-ton chemical laser fired a beam from a C-130H aircraft and destroyed a three-by-three-foot target on the ground.
