Soldier-Centered Approach Helping Lead Ground Modernization Efforts

March 23rd, 2020

WASHINGTON — Nearly two years into its largest modernization overhaul in four decades, the Army looks to continue its momentum of developing new ground systems centered on input from Soldiers.

Testifying before the House Armed Services Committee’s tactical air and land forces subcommittee, the Army’s acquisition chief told lawmakers Thursday that adequate funding is needed to build on those efforts.

“The Army’s modernization program takes time and money,” said Bruce Jette, assistant secretary of the Army for acquisition, logistics and technology. “We are working to achieve efficiency wherever possible and we need sufficient, predictable, sustained and timely funding to ensure a successful outcome.”

REALIGNING FUNDS

In its fiscal year 2021 budget request, the Army has realigned $9 billion to fund its six modernization priorities over the next five fiscal years.

In total, there is now $63 billion over that period aligned against those priorities: long-range precision fires, next-generation combat vehicle, future vertical lift, the network, air and missile defense, and Soldier lethality.

The realigned funds come after senior leaders carried out extensive “night court” sessions that led to the elimination or reduction of 80 programs across the Army.

In the latest budget request, the top program being canceled is about $122 million for the Advanced Precision Kill Weapon System, a guidance kit for helicopter-launched rockets. The largest program reduction is $222 million for upgrades to Bradley Fighting Vehicles.

The Army intends to replace the Bradley with the Optionally Manned Fighting Vehicle. In January, the Army halted its solicitation for a rapid prototype and now plans to solicit it again to gain more interest from industry.

“We’ve made it clear OMFV is continuing,” Jette told lawmakers. “The objective we were pursuing is unchanged. It’s the methodology by which we’re trying to get there.”

Jette also thanked Congress for granting the Army new authorities to strengthen its acquisition process.

As a result of the middle-tier acquisition authority, the Army has been able to rapidly prototype and accelerate select modernization efforts. Currently, there are 11 rapid prototyping efforts and one rapid fielding effort, he said.

In addition, the other transaction authority, or OTA, has allowed the Army to attract small companies and nontraditional businesses. In fiscal 2019, the Army awarded 830 agreements valued at roughly $5 billion, he said.

Jette also credited the unique relationship between his office and Army Futures Command for bringing system concepts and designs to life.

“Together they are aligning requirements, development and acquisition expertise with representatives from testing, logistics, science and technology, and other important Army communities,” he said.

The collaboration has quickly delivered equipment to Soldiers, such as the Enhanced Night Vision Goggle-Binocular and the Command Post Computing Environment, a software system that supports mission command.

“And, in both cases, statement of need to delivering those capabilities was less than 18 months,” Gen. John Murray, the AFC commander, said during the hearing.

The general also noted successful test shots of the Precision Strike Missile and the Extended-Range Cannon Artillery, which both aim to greatly extend the range of two key long-range precision fire delivery systems.

SOLDIER-CENTERED APPROACH

The Army has also relied on Soldiers to play a larger role in developing new equipment.

“In all of our efforts we are leveraging a Soldier-centered design approach to delivering capability, putting Soldiers at the center of our production,” Murray said.

Before, Soldiers typically did not see a new piece of equipment until a limited user test.

“And it usually didn’t fare well because we didn’t have Soldiers involved from the front,” he said. “So that has become a standard principle for everything.”

Soldiers, he said, have been heavily involved with the next-generation squad weapon, as companies vie to replace the M4 carbine and M249 squad automatic weapon.

The Integrated Visual Augmentation System, or IVAS, has been another success of Soldier feedback. Murray said there has already been over 6,000 hours of Soldier touchpoints that have helped engineers make modifications to the system.

“Within this approach, we are committed to learning early and learning often,” he said. “This means focusing on characteristics and working with industry and our Soldiers to make sure that when we do write requirements, we get them right the first time.”

SCUBAPRO Sunday – US Riverine Forces

March 22nd, 2020

The U.S. Navy Riverine Force go back to the beginning of the U.S. Navy. The hay day for Riverine force was during the Vietnam War. The Brown Water Navy had the highest volunteer and retention rate of any unit in the U.S. military. They are also one of the highest decorated units during that time frame. The Riverine Force concept in Vietnam was based on tactics first used in the Revolutionary and Civil War. But they were quickly adapted for the Mekong delta.

During the Indochina War, the French Navy successfully utilized riverine assault craft against Viet Minh forces between 1946 and 1954. In 1955 with the departure of the French, the U.S. Navy sent in a hand full of advisers to help the South patrol the inland waterway. When the U.S. Mobile Riverine Force arrived in 1967, many of the older French craft were still being used by the South Vietnamese Naval Forces. By 1965 the Brown Water Navy was patrolling the over 26,000 square miles of the Mekong delta. The Navy was not the only service working on the waters of Vietnam, the Army, Coast Guard, Air Force, and USMC all worked together.  Below is a link to help you better understand the scope of the River force in Vietnam, and you can also read the book “Brown Water, Black Beret.” It’s a great book to read during quarantine.

US Army Rolls Out New Medical-Training Mannequins

March 22nd, 2020

CAMP BUEHRING, Kuwait — The U.S. Army is rolling out a new program for certified medical-personnel to borrow state-of-the-art medical-training equipment from the Training Aids Service Center on post, scheduled to be fully implemented by this summer.

The medical-simulation unit is a mannequin that emulates many aspects of battlefield casualties to help commanders train their soldiers more effectively in Tactical Combat Casualty Care, in compliance with Department of Defense Initiative 1322.24: Medical Readiness Training (MRT).

“The purpose of this device is for the commanders to employ collective training where a casualty is incurred, and the squad is supposed to react,” said Dr. Jerry P. Higman, Deputy Product Manager of Medical Simulation, U.S. Army Program Executive Office for Simulation, Training, and Instrumentation. “At present we have instruction to field 77 systems across 41 sites.”

The mannequin, named the Tactical Combat Casualty Care Exportable, or TC3X, simulates the three main causes of death on the battlefield: airway obstruction, tension pneumothorax and blood hemorrhage, commonly referred to as the “ABC’s” — airway, breathing, and circulation. The TC3X is fully animatronic and effectively simulates the ABC’s through a heavily-monitored internal system, giving feedback to the soldiers through physical movements and vocalizations.

The movements and vocalizations can be set and controlled by an operator before the training takes place. The controller has a variety of scenarios built in with spaces for custom scenarios. Scenarios range from bullet wounds and shrapnel damage to head trauma and full amputations, requiring soldiers to act accordly in real time.

“You should definitely treat it like you would treat a human,” said Lt. Col. Rickardo Christopher, Product Manager of Medical Simulation, U.S. Army Program Executive Office for Simulation, Training, and Instrumentation. “If you don’t apply correct pressure to the wound, it’ll keep bleeding just like a real human being.”

The mannequin is built to withstand dust, dirt, mild moisture and variations in temperature, necessary for field-operations training.

“You’re working with a high fidelity mannequin, but it is robust,” said Higman. “Do not be afraid to work with the mannequin, in terms of deploying it or taking it to the field. We do not want the medics to have any inhibitions on checking it out.”

“You have to use what you have to get better,” said Christopher. “This mannequin sets the condition for soldiers to increase their overall medical readiness.”

To check out a TC3X for use in training, see the TASC on post to see if and when they are available.

Army Scientists Create Innovative Quantum Sensor – Covers Entire RF Spectrum

March 21st, 2020

ADELPHI, Md. — A quantum sensor could give Soldiers a way to detect communication signals over the entire radio frequency spectrum, from 0 to 100 GHz, said researchers from the Army.

Such wide spectral coverage by a single antenna is impossible with a traditional receiver system, and would require multiple systems of individual antennas, amplifiers and other components.

In 2018, Army scientists were the first in the world to create a quantum receiver that uses highly excited, super-sensitive atoms–known as Rydberg atoms–to detect communications signals, said David Meyer, a scientist at the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory. The researchers calculated the receiver’s channel capacity, or rate of data transmission, based on fundamental principles, and then achieved that performance experimentally in their lab–improving on other groups’ results by orders of magnitude, Meyer said.

“These new sensors can be very small and virtually undetectable, giving Soldiers a disruptive advantage,” Meyer said. “Rydberg-atom based sensors have only recently been considered for general electric field sensing applications, including as a communications receiver. While Rydberg atoms are known to be broadly sensitive, a quantitative description of the sensitivity over the entire operational range has never been done.”

To assess potential applications, Army scientists conducted an analysis of the Rydberg sensor’s sensitivity to oscillating electric fields over an enormous range of frequencies–from 0 to 10^12 Hertz. The results show that the Rydberg sensor can reliably detect signals over the entire spectrum and compare favorably with other established electric field sensor technologies, such as electro-optic crystals and dipole antenna-coupled passive electronics.

“Quantum mechanics allows us to know the sensor calibration and ultimate performance to a very high degree, and it’s identical for every sensor,” Meyer said. “This result is an important step in determining how this system could be used in the field.”This work supports the Army’s modernization priorities in next-generation computer networks and assured position, navigation and timing, as it could potentially influence novel communications concepts or approaches to detection of RF signals for geolocation.

In the future, Army scientists will investigate methods to continue to improve the sensitivity to detect even weaker signals and expand detection protocols for more complicated waveforms.

The Journal of Physics B published the research, “Assessment of Rydberg atoms for wideband electric field sensing,” in its special issue on interacting Rydberg atoms. Army scientists David H. Meyer, Kevin C. Cox and Paul D. Kunz led this research, as well as Zachary A. Castillo from the University of Maryland. This work was supported by the Defense Advanced Research Projects Agency.
