Never lose a soldier again with the Army's new boot-mounted personnel tracker

Army commanders may never have to worry about losing a lieutenant ever again.


The Army last week awarded a $16.5 million contract to Maryland-based defense contractor Robotic Research for boot-mounted trackers so dismounted soldiers can keep tabs on one another in environments where GPS-based systems are ineffective.

The "warfighter localization sensor unit," known as WarLoc, is designed to operate in GPS-degraded and -denied environments such as underground facilities or dense urban terrain. It also resembles a court-ordered ankle bracelet.

"WarLoc's small-form factor and state-of-the-art capability to provide highly accurate localization and positional information in GPS-denied environments make this device a perfect fit for America's forces tasked with defending our freedoms on the front lines," Robotic Research president Alberto Lacaze said in a statement.

WarLoc will be fielded to four deployed brigade combat teams "in various locations" in the near future according to the company.

As the Pentagon reorients from 18 years of counterterrorism operations in the Middle East to "great power competition" with Russia and China, the Army is increasingly focused on locator devices capable of functioning in contested environments where GPS may prove either unreliable or jammed outright.

"Imagine soldiers going inside of a very large building and getting lost or turned around in an underground facility, and someone else is jamming GPS, or blue force tracker stops working," Lacaze told Defense News. "This allows you to continue that capability, even when GPS is jammed either because of natural causes like being underground or because someone's purposefully doing it."

According to the company, the first batch of WarLocs have already been delivered to the service. No word yet on whether or not the WarLoc will be available to soldiers for land nav portion of their Expert Soldier Badge test.

Roughly a dozen U.S. troops showing concussion-related symptoms are being medically evacuated from Al-Asad Air Base in Iraq to Landstuhl Regional Medical Center in Germany, a defense official told Task & Purpose on Tuesday.

In a Galaxy — err, I mean, on a military base far, far away, soldiers are standing in solidarity with galactic freedom fighters.

Sitting at the top of an Army press release from March 2019, regarding the East Africa Response Force's deployment to Gabon, the photo seems, at first glance, just like any other: Soldiers on the move.

But if you look closer at the top right, you'll find something spectacular: A Rebel Alliance flag.

Another 300 lawsuits against 3M flooded federal courts this month as more military veterans accuse the behemoth manufacturer of knowingly making defective earplugs that caused vets to lose hearing during combat in Iraq or Afghanistan or while training on U.S. military bases.

On another front, 3M also is fighting lawsuits related to a class of chemicals known as PFAS, with the state of Michigan filing a lawsuit last week against the Maplewood-based company.

To date, nearly 2,000 U.S. veterans from Minnesota to California and Texas have filed more than 1,000 lawsuits.

GENEVA (Reuters) - North Korea said on Tuesday it was no longer bound by commitments to halt nuclear and missile testing, blaming the United States' failure to meet a year-end deadline for nuclear talks and "brutal and inhumane" U.S. sanctions.

North Korean leader Kim Jong Un set an end-December deadline for denuclearization talks with the United States and White House national security adviser Robert O'Brien said at the time the United States had opened channels of communication.

O'Brien said then he hoped Kim would follow through on denuclearization commitments he made at summits with U.S. President Donald Trump.
