China’s mysterious hypersonic test may take a page from DARPA’s past

"Calling it 'breaking the laws of physics' does not lead to rational scrutiny," Secure World's Victoria Samson said of the recent Chinese hypersonic test.

    New England guardsmen test their skills in Cyber Yankee 2020

    Mark Pomerleau Members of the National Guard from New England states concluded a two-week cyber exercise that sought to test the cyber skills of guardsmen and critical infrastructure operators. Cyber Yankee 2020, which took place July 21-31 in New Hampshire, involved more than 200 National Guard members and their civilian counterparts from across New England states, along with some active-duty partners and participants from local, state and federal agencies. In its sixth year, there was less attendance than previous years due to the coronavirus pandemic, but several were able to participate remotely. “Cyber Yankee is primarily a hands-on keyboard cyber incident response exercise for National Guard soldiers and airmen in FEMA Region 1, which are the six New England states,” said Lt. Col. Woody Groton, a member of the New Hampshire National Guard and the director for Cyber Yankee, according to a Facebook post by the New Hampshire Air National Guard. Groton said in a video that the exercise is primarily focused on the electrical and water sector. The exercise is “a great training opportunity for us to work with those people who would actually own the network that we would potentially respond on and for our soldiers and airmen to get that experience and for the engineers from those various entities, they get the training in working with us,” he said. The Guard units within the various states are a critical resource to defend against cyberattacks when they overwhelm localities. “If a large-scale attack happened against a power company, water company, or any other critical department around the state, we would be able to get activated and help them mitigate the threat,” Capt. Frederick Bond, 103rd Air Control Squadron cyberspace operator and exercise Team 3 lead from the Connecticut National Guard, said in a release. “It's similar to when a storm comes and we help remove fallen trees or shovel snow from roofs to help get critical infrastructure going again.” The friendly blue team had to deal with simulated attacks from an opposing red team. Social media posts were used to simulate a real internet environment, where forces must sift through the noise and discern what information is needed to make decisions and identify threat actors. In one case, these actors defaced a public website. “We found some discrepancies including website, it looks like it may have been defaced. The team is digging into finding the source of that defacement and then making steps to correct it,” Master Sgt. Eric Lewis, a blue team member in the New Hampshire Air National Guard, said in a video. Other actions tested included protecting computer files from being stolen or manipulated. “We received intel that potential threat actors may be using a certain capability to transfer files,” said Senior Airman Stephen LaLuna, 103rd Communications Flight cyber systems operations specialist with the Connecticut National Guard. “We see the traffic that's using it, that sets off a flag on our end to look deeper into that. If we determine it is malicious, we send it up the chain with our findings and recommendations to block it.” Officials explained that one of the most critical aspects of these training events is the partnerships built between Guard units, critical infrastructure operators and government entities so that when a crisis breaks out, everyone is acquainted. “We have built enduring partnerships with state government and the critical infrastructure sector. Something that if we did have a major cyberattack against one of those, we would be ready to respond and already know each other,” Groton said.

    The Army and Marine Corps are looking at what troops will need to fight in megacities, underground

    By: Todd South A recent Army and Marine war game that included engineers, academics and other defense representatives evaluated how troops could use experimental technologies to fight in dense urban areas and underground. The U.S. Army Subterranean and Dense Urban Environment Materiel Developer Community of Practice is a working group that has conducted three prior workshops that set the challenges of fighting in those environments. “Fighting in dense urban environments and the unique challenges it presents is still not totally understood, and this study was the front-end look at identifying and defining those materiel challenges to drive where investments need to be for this operational environment,” said Bob Hesse, technical lead coordinator for the Community of Practice. The most recent “tabletop” exercise looked at the gear troops might need to get through those intense battle scenarios, according to an Army release. Soldiers and Marines worked as friendly and enemy forces during the exercise, evaluating 48 experimental future technologies. One such piece of tech would be using sensors that attach to the exterior building wall to help troops visualize the interior layout. And every advantage in these terrains can help. “Everything that Marine formations or Army formations have to do is more difficult when you take it into an urban environment,” explained Marine Corps Brig. Gen. Christian Wortman, commanding general of the Marine Corps Warfighting Laboratory, and vice chief of Naval Research. The Marines recently launched Project Metropolis II, a five-year effort to better prepare Marines for likely future urban battles. “Across the warfighting functions — whether it's intelligence, surveillance or reconnaissance, collections, maneuver, force protection, command and control, logistics and sustainment — all of those things are complicated and challenged by the compartmentalized terrain that's present in the urban environment and the three-dimensional nature of the urban environment,” Wortman said. And that multi-dimension challenge grows with the subterranean. For both above ground and underground, robotics will play a major role. The Squad X project by Defense Advanced Research Projects Agency, for example, is blending robots into dismounted formations. Soldiers with the 10th Mountain Division and 101st Airborne Division along with Marines at Camp Lejeune, North Carolina, are experimenting with four submissions for the Squad Multipurpose Equipment Transport gear mule that will carry fuel, water, ammunition and equipment for a squad through rough terrain over 60 miles on a 72-hour mission. Lt. Col. Calvin Kroeger, battalion commander for the 35th Engineering Battalion, ran one of the blue teams during the tabletop exercise. Participants ran scenarios such as a high-intensity fight, a traditional counter-insurgency and a security force-assisted mission, all under the conditions of a megacity. But the wargaming went beyond simply clearing buildings and attacking objectives. Teams countered enemy social media campaigns, communicated underground, and assessed the second- and third-order effects of engaging the enemy with lethal munitions, which could impact local power, gas and water networks. “How we employ our capabilities changes as you move from a high-rise platform to urban cannons,” Kroeger explained. “But you're also looking at everything under the ground as well, where you can't use a conventional means like a mortar system to shape the battlefield, so that the enemy doesn't shape it for you.” As team members fix on what materiel needs might best serve troops, Hesse said the subject matter experts will assess how well the tech will meet military goals. For example, if there is an aerial technology that might help troops locate enemy forces, even though the troops can't see them because of the skyline, his team would then analyze that technology and determine how well it meets Army standards and if it needs to be modified. “We will now transition from the workshop learning to live experiments and replicate the unique conditions in real venues. We're taking the materiel campaign of learning and now transforming that into action,” Hesse said. https://www.armytimes.com/news/your-army/2019/01/09/the-army-and-marine-corps-are-looking-at-what-troops-will-need-to-fight-in-megacities-underground/

    Thales développe un casque optimisé pour les hélicoptères militaires

    Thales va fournir à l'armée française une version optimisée du casque TopOwl, fabriqué à Mérignac (Gironde), afin d'aider les hélicoptères des forces spéciales à évoluer dans des conditions extrêmes (basse altitude, obscurité totale, atterrissage dans le brouillard...). Destiné aux hélicoptères NH90 de NHIndustries, le nouveau dispositif de réalité augmentée permettra aux pilotes d'avoir accès à la vision de nuit directement dans le viseur du casque, gr'ce à des amplificateurs de lumière, ce qui évitera l'emploi de jumelles de vision nocturne.
