Military personnel and security agents often face significant physical risks during conflict and engagement situations, particularly in urban operations. Ensuring the rapid and accurate communication of incidents involving injuries is crucial for the timely execution of rescue operations. This article presents research conducted under the scope of the Brazilian Navy's ``Soldier of the Future'' project, focusing on the development of a Casualty Detection System to identify injuries that could incapacitate a soldier and lead to severe blood loss. The study specifically addresses the detection of soldier falls, which may indicate critical injuries such as hypovolemic hemorrhagic shock. To generate the publicly available dataset, we used smartwatches and smartphones as wearable devices to collect inertial data from soldiers during various activities, including simulated falls. The data were used to train 1D Convolutional Neural Networks (CNN1D) with the objective of accurately classifying falls that could result from life-threatening injuries. We explored different sensor placements (on the wrists and near the center of mass) and various approaches to using inertial variables, including linear and angular accelerations. The neural network models were optimized using Bayesian techniques to enhance their performance. The best-performing model and its results, discussed in this article, contribute to the advancement of automated systems for monitoring soldier safety and improving response times in engagement scenarios.

Fox News State Department and foreign policy correspondent Gillian Turner has the latest on the Israel-Hamas war on'Special Report.' Two Nigerian military personnel will face a court martial over the killing of 85 villagers in a military drone attack in December in the West African nation's conflict-battered north, authorities said, prompting calls from a rights group Friday for more transparency and justice for victims. The two personnel will be subjected to military justice proceedings "for acts of omission or commission" after investigations found that the civilians killed by the strike "were mistaken for terrorists," Nigeria's Defense Headquarters spokesperson Maj. Gen. Edward Buba said in a statement Thursday without providing further details. Nigeria's military often conducts air raids as it fights the extremist violence and rebel attacks that have destabilized Nigeria's northern region for more than a decade, often leaving civilian casualties in its wake.

Warning: Some readers may find some of the scenes described in this article disturbing. Kyiv, Ukraine – Ivan Ukraintsev, a stern-faced insurance broker turned director of a wartime charity providing crucial aid to Ukraine's military forces, is on a mission: to help Ukraine win the drone war. He is a polite but no-nonsense character, and he is here to talk about drones. "If we [Ukraine] had enough drones, we could end this war in two months," he says firmly. Ivan, who heads up the charity Starlife, had recently returned from overseeing a drone delivery to Bakhmut, a city in eastern Ukraine that has become the focal point for months of bloody battles between Ukrainian and Russian forces. Trench warfare, pockmarked and corpse-ridden swathes of no man's land, and constant artillery bombardments have drawn comparisons to battlefield conditions during World War I.

A new academic program developed at MIT aims to teach U.S. Air and Space Forces personnel to understand and utilize artificial intelligence technologies. In a recent peer-reviewed study, the program researchers found that this approach was effective and well-received by employees with diverse backgrounds and professional roles. The project, which was funded by the Department of the Air Force–MIT Artificial Intelligence Accelerator, seeks to contribute to AI educational research, specifically regarding ways to maximize learning outcomes at scale for people from a variety of educational backgrounds. Experts in MIT Open Learning built a curriculum for three general types of military personnel -- leaders, developers, and users -- utilizing existing MIT educational materials and resources. They also created new, more experimental courses that were targeted at Air and Space Forces leaders.

A third Russian airfield is ablaze from a drone attack, a day after Ukraine demonstrated an apparent new ability to penetrate hundreds of kilometres deep into Russian airspace with attacks on two Russian air bases. A drone struck an airfield in the Russian region of Kursk bordering Ukraine, setting fire to an oil storage tank. Russia said three of its military personnel were killed in what it said were Ukrainian drone attacks on two Russian air bases hundreds of kilometres from the frontlines in Ukraine. Kyiv did not directly claim responsibility. Ukraine's military intelligence chief said Russia had enough high-precision missiles to conduct several more big air raids on Ukraine before it runs out of stock.

If you think of robots in the military, your mind may conjure dystopian images of science-fiction battlefields with AI-powered machines trading laser fire. But in a much more humane application, UK researchers are developing a potentially lifesaving medical system equivalent to a VR triage video call. University of Sheffield researchers are working on a telepresence system to treat military personnel during combat. The plan is for offsite medics to don virtual reality headsets and control a battlefield robot. The machine can take the patient's vitals with the same technology used in robotic surgery.

Fox News national security correspondent Jennifer Griffin provides insight on responding to drone attacks in Ukraine on "America Reports." The Paris-based dissident organization National Council of Resistance of Iran (NCRI) accused the Iranian regime of furnishing Russian strongman Vladimir Putin's army with more than 3,500 drones for his scorched-earth war against Ukraine. According to reports from the social network of the People's Mojahedin Organization of Iran (PMOI/MEK) inside the Islamic Republic, "Iran's UAV [unmanned aerial vehicle] sale contract to Russia includes various offensive drones, including Shahed-129, Mohajer-6 and suicide drones Shahed-136 and Shahed-131." MEK is part of the National Council of Resistance of Iran umbrella organization. The NCRI dossier states, "Tehran has sold more than 3,500 UAVs to Russia. Most of these were made at the factories of the Ministry of Defense, with others produced by the factories of the Iranian Aviation and Space Industries Association (IASIA)."

Congress is deciding whether to give $424.2 million to purchase more military-grade HoloLense headsets from Microsoft after more than 80 percent of soldiers testing the device experienced'mission-affecting physical impairments' in less than three hours of use. The US Army has been testing the augmented reality device since 2018, which claims to improve training and missions on the battlefield by projecting digital information on the screen while allowing users to interact with the physical world. The HoloLens, however, is causing headaches, eyestrain and nausea, and acceptance of the technology'remains low' - a finding that could pause the entire project. Microsoft received $480 million in 2018 to develop prototypes, but the technology is still'experiencing issues' that could force officials to pull their order of more than 100,000 unites. Microsoft received $480 million in 2018 to develop prototypes, but the technology is still'experiencing issues' and making soldiers testing it nauseas, along with giving them headaches In all, the contract is set to amount to up to $21.88 billion over the next decade, with a five-year base agreement that can be extended for another five years.

Greetings from Cupertino, California, where the temperature has cooled down to a far more reasonable 101 degrees. It's a nice change from the 109 degrees we hit here on Tuesday. There was no robotics news to speak of, but that's why we're coming to you a day late with Actuator. I'll try not to make a habit of it. We've got an interesting selection of robotics news this week. It's a testament, really, to how broad this field has become in recent decades.

Yesterday evening, the Washington Post broke the blockbuster news that FBI agents who searched former President Trump's Mar-a-Lago residence on Monday were looking for "nuclear documents," a phrase that immediately set off alarms inside national security circles. The nation's nuclear systems and plans are considered among the most sensitive and most narrowly known secrets. Trump denied the report, calling the "nuclear weapons issue" a "hoax." But assuming the Post's reporting is correct, what could such a vague phrase as "nuclear documents" mean, and what could we learn about such a category? Broadly speaking, the US intelligence and defense communities would possess four different categories of files that might be considered "nuclear documents": nuclear weapon science and design; other countries' nuclear plans, including the nuclear systems and command of allied nations (UK, France) and adversaries (Russia, China, North Korea, Iran), as well as countries whose nuclear programs exist in a more gray zone (Israel, India, Pakistan); details on the United States' own nuclear weapons and deployments; and details on US nuclear command & control procedures, known in Pentagon parlance as NC2.
