  Army to Receive 7.62mm Squad Marksman Rifles as Early as Next Year

  By Matthew Cox Heckler & Koch Defense Inc. will soon begin delivering thousands of 7.62mm squad-designated marksman rifles to the Army to give infantry and other close-combat units a better chance of penetrating enemy body armor. H&K will deliver "between 5,000 and 6,000" variants of the G28 rifle, which the Army plans to issue as its new squad designated marksman rifle (SDMR), according to a July 12 H&K news release. Under the agreement, the rifles will be manufactured by H&K in Oberndorf, Germany, and will begin to arrive in the H&K-USA facility in Columbus, Georgia, early next year, according to the release. Once there, H&K-USA workers will install scopes and mounts purchased by the Army under a separate agreement. "This is a significant achievement for Heckler & Koch," H&K-USA's chief operating officer, Michael Holley, said in the release. "The HK SDMR system will add much-needed capabilities to virtually every squad in the Army. We are honored by this opportunity." The new SDMRs are part of an interim effort to make squads more lethal ahead of the Army's fielding of the Next-Generation Squad Weapon system sometime in 2022, service officials have said. In May 2017, Army Chief of Staff Gen. Mark Milley told Senate Armed Services Committee members that the service's current M855A1 Enhanced Performance Round will not defeat enemy body armor plates similar to the U.S. military-issue rifle plates such as the Enhanced Small Arms Protective Insert, or ESAPI. As a short-term fix, the Army selected the G28 as its M110A1 Compact Semi-Automatic Sniper System in 2016, to be used with the service's new 7.62mm enhanced performance round to give squads more penetrating power. In the past, the Army relied on the Enhanced Battle Rifle, or EBR, 14 -- a modernized M14 equipped with an adjustable aluminum stock with pistol grip, scope and bipod legs -- to fill the growing need by infantry squads operating in Afghanistan to engage enemy fighters at longer ranges. But the EBR is heavy, weighing just under 15 pounds unloaded. The M110A1 weighs about 11 pounds. In the long term, the Army is working with gunmakers to develop the new Next Generation Squad Weapon (NGSW) that is slated to fire a special, government-produced 6.8mm projectile that promises higher velocities at greater ranges, service officials say. The program is being designed to produce an automatic rifle version to replace the M249 squad automatic weapon and a carbine version to replace the M4 carbine. Army officials said recently that they expect to begin receiving prototypes of the NGSW in July and August and that the weapon could be fielded to units beginning in late fiscal 2020. https://www.military.com/daily-news/2019/07/12/army-receive-762mm-squad-marksman-rifles-early-next-year.html

  DARPA: With Insights from Integration Exercise, SubT Challenge Competitors Prepare for Tunnel Circuit

  Nine teams hailing from four continents gathered in Idaho Springs, Colorado, the week of April 5-11, 2019, to test autonomous air and ground systems for navigating the dark, dangerous, dirty, and unpredictable underground domain. The SubT Integration Exercise, known as STIX, took place at the Colorado School of Mines' Edgar Experimental Mine. The event provided a shakeout opportunity for competitors in advance of the Tunnel Circuit in August, the first of three subdomains that teams will tackle in DARPA's Subterranean Challenge. The teams were divided into three groups. Each group had one day to experiment with their various systems during multiple runs in the mine, followed by a second day in which each team attempted a one-hour mock, scored run. Teams could earn points by accurately locating, identifying, and reporting artifacts placed within the tunnels. Artifacts included thermal manikins, backpacks, fire extinguishers, cell phones, and cordless drills – all inspired by objects an end user such as a warfighter or first responder might encounter. The mine environment presented teams with low light, high dust, metal rails, and irregular terrain. The DARPA team added to the complexity with a theatrical smoke machine, which mimicked real smoke a warfighter or first responder could contend with in an emergency response scenario, for example. “It was amazing to see the progression from day one into day two for each team as they explored the tunnels of the mine and began to understand just how complex and unknown these underground environments can be,” said Timothy Chung, program manager for the Subterranean Challenge in DARPA's Tactical Technology Office. “It's not just about testing whether there's enough light or if robots can drive a few meters. It's about how all that has to come together in a difficult environment and the teams are experiencing the challenge of integration in addition to technology development.” The competitors at STIX included a mix of DARPA-funded and self-funded teams: CERBERUS University of Nevada, Reno ETH Zurich, Switzerland Sierra Nevada Corporation University of California, Berkeley Flyability, Switzerland CoStar: Collaborative SubTerranean Autonomous Resilient Robots Jet Propulsion Laboratory California Institute of Technology Massachusetts Institute of Technology KAIST, South Korea CRETISE: Collaborative Robot Exploration and Teaming In Subterranean Environments Endeavor Robotics Neya Systems CSIRO Data 61 Commonwealth Scientific and Industrial Research Organisation, Australia Emesent, Australia Georgia Institute of Technology CTU-CRAS Czech Technical University in Prague, Czech Republic Université Laval, Canada Explorer Carnegie Mellon University Oregon State University MARBLE: Multi-agent Autonomy with Radar-Based Localization for Exploration University of Colorado, Boulder University of Colorado, Denver Scientific Systems Company, Inc. PLUTO: Pennsylvania Laboratory for Underground Tunnel Operations University of Pennsylvania Exyn Technologies Ghost Robotics Robotika Robotika.cz, Czech Republic Czech University of Life Science, Czech Republic Following the Tunnel Circuit, teams will compete in the Urban Circuit, which will focus on underground urban environments such as mass transit and municipal infrastructure; and the Cave Circuit, which will focus on naturally occurring cave networks. Locations for the circuit events have not been announced. Qualification is ongoing for the circuit events. Requirements can be found in the SubT Qualification Guide available on the Resources Page. Teams interested in joining either the virtual or systems tracks can still register and are encouraged to join the SubT Community Forum to exchange ideas, explore teaming opportunities, and receive updates on the Challenge.
