Analog Cold-Chain Transport: CRO 2U Blood Transport Container

Thursday, February 19th, 2026

CRO has developed a two-unit (2U) whole blood transport container designed to accept multiple Commercial Off-the-Shelf evaporative cooling engines. The system is intended to sustain up to 42 hours of low-titer O whole blood (LTOWB) cooling within transport temperature parameters (10°C), depending on configuration and operating conditions.

This solution reduces EM signature, provides indefinite non-powered cooling with appropriate consumable resupply, and addresses delayed MEDEVAC during LSCO.

Background

Contemporary large-scale combat indicates that the increased use of unmanned aircraft systems has expanded persistent ISR (intelligence, surveillance, and reconnaissance) coverage and reduced freedom of maneuver across the battlespace. In LSCO (Large-Scale Combat Operations), units should expect extended disruption to communication, increased sustainment friction, and periods of constrained movement due to persistent aerial observation and strike risk.

These conditions intensify requirements for distributed small-unit operations and longer-duration self-sustainment. Contested airspace and massed fires increase the likelihood of delayed evacuation and degraded medical evacuation times. As evacuation timelines extend, casualty outcomes become increasingly dependent on Prolonged Field Care to include reliable cold-chain sustainment for blood products in austere conditions.

Commanders and medical planners should consider cold-chain solutions that reduce reliance on powered systems and provide resilient, low-complexity backup options consistent with DDIL (Denied, Degraded, Intermittent, and Limited) operating conditions.

Indefinite Cooling with Resupply

Commercially available evaporative cooling systems can provide a non-electric (“analog”) cooling method that reduces reliance on batteries and powered refrigeration in constrained environments. Chemical heat sources can drive phase-change and evaporation processes that transfer cooling to a cold plate without active electrical power, enabling extended cooling duration with appropriate consumable resupply.

Approach 

Figure 1: Concepting a 2U container with evaporative cooling engines
To integrate evaporative cooling into whole blood transport, we addressed two problems in parallel. First, no Commercial Off-the-Shelf (COTS) blood transport container uses evaporative cooling engines, so we had to develop the container architecture from the ground up. Second, the required form factor is not achievable by simply stripping down two single-unit containers and placing them side-by-side, and legacy GWOT-era medical bags were not designed to carry blood at all. Prior solutions largely relied on retrofitting existing equipment. Our approach was to design the 2U container first, then design a bag purpose-built to accept and retain it. This effort resulted in the CRO DCR 26L– a larger, more capable POI medical bag engineered to integrate the 2U Blood Transport Container (BTC).

Production 

Figure 2: Production Design and foam integration
Design for Manufacturing (DFM) began by establishing baseline dimensions using layered foam prototypes. After completing the initial CAD, we evaluated expanding-foam insulation options and refined the flange geometry to prevent foam spillover during assembly. Once the container profile was finalized, we integrated the evaporative cooling engine retention features into the production design.

Other Considerations

EM Signature Reduction

In a contested electromagnetic spectrum, electromagnetic signature management is an increasingly relevant survivability consideration. Common medical and support equipment can produce detectable electromagnetic (EM) emissions through electromagnetic interference and unintentional radiators, even when the equipment is not intended to transmit. Distributed small units should account for these emissions and, where practical, mitigate leakage and reduce reliance on powered systems, while recognizing that many battlefield sensor payloads remain primarily electro-optical/infrared (EO/IR).

Targeting Medical Personnel

Medical personnel have faced an elevated risk of engagement in contemporary conflicts, including documented allegations of targeting by the Armed Forces of the Russian Federation. When only medics carry distinctive medical loadouts, visible differentiation can increase exposure to observation and engagement. By selecting and distributing common carriage systems across the element, units can reduce target indicators that single out medical personnel, as multiple personnel will carry similar bags and mixed-use equipment. Preventing medic casualties preserves morale, maintains continuity of care, and sustains overall unit effectiveness.

Fort Benning Integrates Virtual Drone Training into OSUT Program of Instruction

Thursday, February 19th, 2026

FORT BENNING, Ga. — As small unmanned aircraft systems, sUAS, become a defining feature of the modern battlefield, the Maneuver Center of Excellence is ensuring every new Soldier has a high-tech edge.

One-Station Unit Training trainees are now undergoing a 10-hour sUAS familiarization course integrated into their formal program of instruction. Using Virtual Battle Space 4 software and the Virtual Drone Collective Trainer plug-in, Infantry and Armor trainees master flight mechanics before stepping onto a live flight line.

The 12-lane curriculum, modeled after the 75th Ranger Regiment’s Ranger Robotics Lethality Course, is designed to take a Soldier from basic “buttonology” — learning the controller interface — to advanced tactical reconnaissance and lethal kinetic strikes.

“The Army has always used simulation-based training to reduce noise, training costs, and wear and tear on equipment and resources,” said Jayson D. Karch, a training specialist with the Maneuver Center of Excellence Directorate of Training and Doctrine. “This enables Soldiers from across the Army to receive immersive, life-like, low-cost training on equipment they have minimal experience operating, without risk of damage to equipment, personnel, or resources.”

The move toward simulation-based training addresses the logistical challenge of training thousands of Soldiers annually. By using the Virtual Drone Collective Trainer software plug-in, developed by the Combined Arms Center-Training Innovation Facility at Fort Leavenworth, Kansas, the Army can provide immersive training at scale.

“While live flight is an important and vital portion of certifying an sUAS operator, new operators use simulations to build basic skills without all the resources required for live flight,” said Rory O’Brien, an MCoE simulation specialist. “Given the number of Soldiers trained in Infantry and Armor OSUT, there aren’t enough resources to allow every Soldier to fly a live sUAS, so virtual simulations allow us to train the skills at scale using less resources.”

The training is divided into three distinct phases: flight training, basic tactical training and a culminating assessment. During the tactical phase, trainees use night vision, thermal, and infrared cameras to identify enemy personnel and vehicles before conducting simulated drone strikes.

The Army’s goal is not to turn every Soldier into a certified pilot, but to ensure every Soldier is familiar with a combat enabler they will encounter in future formations. The simulation also serves as a talent-scouting tool; trainees who demonstrate above-average proficiency are considered for the formal sUAS Operators Course following graduation.

The MCoE plans to publish these training lanes on the milGaming website, allowing units across the force to download and utilize the same scenarios for home-station training.

The integration of sUAS training into OSUT represents a fundamental shift in how the Army prepares for the modern, transparent battlefield. By prioritizing digital literacy and technological proficiency from day one, the MCoE is ensuring that the next generation of Infantry and Armor Soldiers is not just keeping pace with change but driving it. As these Soldiers transition to the operational force, they provide a ready, lethal, and tech-capable backbone for the multidomain formations of tomorrow.

Visit Mystery Ranch at Enforce Tac at the Mehler Stand

Wednesday, February 18th, 2026

Mystery Ranch will be exhibiting at next week’s Enforce Tac in Nürnberg, Germany at the Mehler stand. This will be my friend and MR International Sales Manager E-van’s first trip to Enforce Tac so stop by and catch up.

Sean Evangelista, known throughout the industry as “E-van”, is the new International Military Sales Manager for Mystery Ranch. He spent nearly 20 years in U.S. Navy Special Operations and later founded the apparel brand Thirty Seconds Out, which he successfully exited in 2024.

Before joining Mystery Ranch, Sean worked full-time as a mountain guide for four years, leading clients through mountaineering, backcountry skiing, ice climbing, rock climbing, alpine routes, and hut-to-hut treks. His guiding experience spans both Alaska and Colorado.

He began using Mystery Ranch packs during his time in Special Operations and continued relying on them throughout his guiding career — from expeditions to the summit of Denali to demanding backcountry ski and ice-climbing missions across Colorado. The packs became a constant in environments where reliability wasn’t optional.

Sean said, “I’ve used Mystery Ranch packs for years, long before working here was even on my radar, because they’re comfortable and they don’t fail you. That really matters when the terrain and the mission are high-consequence. With other brands, I’ve blown out stitching, bent aluminum frames, and torn more packs than I can count. That’s the last thing you want to deal with, especially on dangerous objectives. Mystery Ranch has never failed me.”

Sean will be at the EnforceTac tradeshow in Nuremberg, Germany, 23–25 February 2026, taking meetings at Mehler/Lindnerhof, Hall 7A, Booth 7A-333.

To schedule a meeting, he can be reached at:

Project Manager Soldier Lethality Relinquishment of Charter

Wednesday, February 18th, 2026

Fort Belvoir, Va

PICATINNY ARSENAL, N.J. –?After three years of dedicated leadership, Colonel Jason Bohannon relinquished his charter as the Project Manager for Soldier Lethality (PM SL) during a ceremony on February 6, 2026.?The traditional military ceremony marked the formal transfer of responsibility for the organization, which is tasked with ensuring Soldiers have overmatch capabilities in individual and crew-served weapons.

Brigadier General Troy Denomy, Capability Program Executive Ground, presided over the event and presented Col. Bohannon with the Legion of Merit. The award recognized Bohannon’s diligent leadership and oversight of a portfolio critical to the nation’s warfighters. Bohannon’s superior initiative, outstanding leadership, and personal courage are a testament to both the organization and the U.S. Army.

Upon assuming command in August 2023, Bohannon stated his goal was to “field the most lethal small arms that ground forces have ever seen.”

His three years as Project Manager were marked by a steadfast commitment to that vision, overseeing the continuous improvement and fielding of systems that enhance both the survivability and lethality of the American Soldier.

Assisting in the ceremony was the Senior Enlisted Advisor for Project Manager Soldier Lethality, Master Sgt. Daniel Saucedo. The event was narrated by Maj. Jonathan DiBianca, and the invocation was provided by Lt. Col. Micah Rue, former Product Manager for Soldier Weapons.

SEAM: Modern Gear Management Personalized for You

Tuesday, February 17th, 2026

DETROIT ARSENAL, Mich. — A Soldier’s strength is built on more than courage and rigorous training — it’s also in the gear worn on their bodies, stowed in their rucksacks and carried into conflict.

Diligent equipment management has always been a cornerstone of readiness. As the nature of warfare rapidly evolves, the U.S. Army is launching a powerful tool that will transform how today’s forces prepare for tomorrow’s fight, delivering the accuracy, agility and speed needed to succeed on the modern battlefield.

The Soldier Equipping and Asset Management System, or SEAM, represents a groundbreaking new era of organizational clothing and individual equipment, OCIE, management.

“SEAM puts OCIE control right where it belongs — in your hands,” said Command Sgt. Maj. Kofie B. Primus of the U.S. Army Tank-automotive and Armaments Command. “From managing [central issue facility] appointments to tracking OCIE to stay mission-ready, SEAM gives you an intuitive, tech-powered way to own every step of your equipment journey.”

The next generation of OCIE management

Militaries worldwide have long struggled with a universal challenge: how to track millions of items — from uniforms and helmets to weapons — assigned to thousands of soldiers, across thousands of sites, in constant motion.

SEAM offers a next-generation logistics solution. The digital, cloud-based platform centralizes and streamlines OCIE management across echelons in real-time, tracking individual pieces of equipment all the way down to the user level.

As the Army pursues greater lethality and readiness, SEAM supports informed decision-making, curtails waste and enhances both convenience and clarity — with the warfighter squarely in the driver’s seat.

Soldiers will be able to easily order and monitor their gear through SEAM’s common access card-enabled online portal. The site is similar to many popular online shopping platforms, with the ability to search for items, view item details, add items to a shopping cart, submit orders and view order status.

It even has photos of each piece of OCIE, so Soldiers can visually confirm their inventory.

Records in SEAM will remain accurate and up-to-date as Soldiers move between units and assignments. Legacy and end-of-life items that the Army has determined have no economic value can be automatically removed, and duplicate items flagged.

The SEAM portal also has a mechanism that lets Soldiers schedule appointments at central issue facilities, or CIFs.

“SEAM brings OCIE management into the digital age, giving Soldiers the power to browse, schedule and equip with confidence and control,” Primus said.

SEAM was designed specifically to enhance Soldiers’ OCIE experience. But perhaps its most impactful feature is what it offers commanders and other decision-makers: real-time readiness insight.

The platform is being integrated with existing Army information technology systems and incorporates data from human resources, logistics, training and readiness domains, providing the first truly holistic view of the Army’s vast OCIE enterprise. Leaders and logisticians will be better able to forecast future needs based on force demands.

TACOM, as the central manager of the OCIE enterprise, is leading the SEAM initiative.

When SEAM rolls out across the Army on Feb. 17, it will be accessible anytime, anywhere, through government-approved devices — even cell phones.

Why is SEAM revolutionary?

SEAM is replacing Installation Support Module-Central Issue Facility, ISM-CIF, the Army’s primary legacy system for OCIE management.

In use for the better part of two decades, ISM-CIF lacks modern OCIE direct ordering and asset-fielding capabilities. Its reliance on local records and non-integrated databases can lead to lapses in accountability.

SEAM was designed to eliminate those gaps at every stage, from the day OCIE is issued through end-of-lifecycle turn-in.

Unit leaders will be able to instantly see whether every Soldier is properly equipped. Soldiers will notice a smoother process for signing and validating records.

Under SEAM, OCIE guesswork evaporates.

“Every time a Soldier is issued gear, turns in gear, or has a change to the clothing record, he or she will be notified to validate the record,” said Chief Warrant Officer 4 Allen Flagg, CIF accountable property officer, Massachusetts Army National Guard.

Flagg noted a greatly improved process for dealing with obsolete items.

“If there is a recalled item, such as if an eye pro has been removed from the [Authorized Protective Eyewear] list, SEAM will notify the Soldier that the item should be disposed of, and a new request put into SEAM for an updated eye pro,” he said.

SEAM has a host of other advantages. It will enable the proactive fielding of equipment, ensure resources are positioned efficiently and simplify access to information about shortages and trends.

Unlike ISM-CIF, SEAM doesn’t use technical language that can be difficult to understand, said Ross Pursifull, SEAM mission lead at TACOM’s Integrated Logistics Support Center. Pursifull’s integral role in building SEAM included business process reengineering, user interface design and cataloging more than 7,000 photos of OCIE.

“All the strange codes that I had to decipher on my old OCIE record are gone,” he said. “Now, it’s pictures and plain English.”

The Army is launching SEAM amid a sweeping, force-wide transformation that promotes the use of emerging technologies and data and analytics.

“As the Army moves more toward leveraging data to inform decisions, SEAM is the modern-day method to ensure Soldiers have the right equipment they need to perform their tactical missions,” said recently retired Command Sgt. Maj. Jimmy Sellers of U.S. Army Materiel Command.

Soldiers can learn more about SEAM by reading the knowledge articles on the site. Training is underway for online direct ordering managers,supply sergeants, CIF and regional logistics support center personnel.

ISM-CIF will sunset by the end of 2026.

Modernization, readiness drive SEAM’s creation

SEAM grew out of the realization that as the Army modernizes its equipment and weapons, it needed a cutting-edge OCIE system to match.

Army officials have aggressively pushed in recent years to update the equipping enterprise to better serve Soldiers and units. A 2023 executive order directed CIF reform and the implementation of OCIE online direct ordering.

That order was a catalyst behind SEAM’s creation, said Adam Charczenko, SEAM portfolio manager and TACOM CIO/G6.

Platform development began in mid-2024. TACOM worked with several partners on the complex, highly collaborative effort, said Robert Ignozzi, branch chief for OCIE, TACOM Integrated Logistics Support Center.

“We now have better asset visibility, an improved, modern ordering experience and a much more stable platform,” he said.

TACOM is a subordinate command of AMC. Its partners in the project included Headquarters Department of the Army G-4; Forces Command, now part of Western Hemisphere Command; Training and Doctrine Command, now T2COM; U.S. Army Europe and Africa; U.S. Army Pacific; Army National Guard; U.S. Army Reserves Command; U.S. Army Cadet Command; Army Sustainment Command, Program Executive Office Soldier; and the Office of the Chief Information Officer.

No group played a more important role in SEAM than Soldiers. Their critical insight and feedback literally shaped how the system looks and works.

“The goal here was to put the power in Soldiers’ hands,” Charczenko said.

In May 2025, Lt. Gen. Heidi J. Hoyle, then-deputy chief of staff, G-4, issued a memo announcing the initial implementation of SEAM as the Army’s new system of record for OCIE.

As SEAM expands in capability and reach, officials expect it will revolutionize tasks for warehouses, issuing facilities and elsewhere. The system is absorbing the capabilities of the Standard Management Asset Readiness Tool, Mobility Inventory Control and Accountability System, Automated Personal Clothing Request system and the systems for ordering heraldry and veterans’ medals.

“As we continue to implement enhancements and integrate new systems, SEAM will become an even better system for the mission,” Michael Santos, SEAM IT project manager, TACOM CIO/G6, said.

Looking ahead

SEAM isn’t just a software upgrade. It represents a foundational shift in how the Army supports and equips the entire fighting force.

By uniting all facets of OCIE management into one data-centric system, SEAM will enable warfighters to operate quickly and with greater precision. That directly translates to increased lethality and readiness — core priorities of U.S. Secretary of War Pete Hegseth.

In a rapidly shifting global landscape, SEAM underscores the Army’s broader push toward a more modern, digitally focused sustainment system. It enhances readiness and operational effectiveness at speed and scale, promising a future where equipping is faster, easier and more dependable, from the strategic level all the way to the tactical edge.

101st Airborne Division (Air Assault) Conducts UAS Competition Tryouts, Showcasing Innovation and Readiness

Tuesday, February 17th, 2026

FORT CAMPBELL, KY – The 101st Airborne Division (Air Assault) conducted competitive tryouts for its UAS team on Jan. 12, 2026, here, identifying Soldiers who will represent the division in an upcoming Army UAS competition while reinforcing the unit’s commitment to innovation, readiness and modernization across the force.

Held at Fort Campbell, the tryouts brought together Soldiers from across the formation who demonstrated technical skill, adaptability and problem-solving abilities while operating unmanned aerial systems.

“The Army has sent a very clear demand signal to identify and employ the best drone teams and best drone operators, ” said Chief Warrant Officer 2 Page Frazier, a member of the Robotics and Autonomous Integration Directorate. “And here at the 101st Airborne Division we are prepared to answer that call.”

Soldiers across the formation were evaluated on their physical endurance through the Air Assault obstacle course, techniques on how to employ a UAS, and how to navigate a drone system in a confined area. These attributes that were being evaluated reflected how emerging technologies are increasingly integrated into modern battlefield operations.

“The most challenging part about the tryouts so far is the air assault course, mixed with running to the nets, and then flying around, ” said Spc. Markus Sund, a participant in the drone tryouts.

This event directly supports the Army’s broader modernization strategy, and places emphasis on the importance of unmanned systems in future conflicts which is evolving the modern-day battlefield. Division leadership within the 101st Airborne Division hones in on the concept that innovation is a critical component of lethality and readiness.

As the Army continues to integrate advanced technologies into training and operations, the division sets forth to remain the trailblazers of that transformation. Through events like the UAS competition tryouts, the division is ensuring its Soldiers are equipped, empowered and prepared to meet tomorrow’s challenges head-on.

The selected team will continue training in preparation for the upcoming Army drone competition, representing the division’s commitment to excellence, adaptability and innovation across the force.

Picatinny – How It Really Works!

Monday, February 16th, 2026

This was shared by Spuhr on Instagram.

When the Picatinny rail (MIL-STD-1913) was originally designed, it was intended to use only the 45-degree angled surfaces for clamping and reference (highlighted in green on the drawing). The tolerance to the top flat surface was deliberately made very large.

Advantages of the original design (green surfaces):

• A QD mount can be attached and detached on a huge variety of rails with extremely tight control — total width tolerance is only about 0.1 mm!

• This makes the system very forgiving of manufacturing variations between different rails.

Disadvantages:

• The mount will always sit slightly canted depending on the exact width of the rail.

• For most practical purposes, this doesn’t matter at all… but it drives people with OCD absolutely crazy…

NATO’s recommendation since 2009 (STANAG 4694): Use three surfaces instead (highlighted in red): the two 45-degree sides plus the top flat as the primary reference.

Advantages:

• The mount will always sit perfectly straight and level

Disadvantages:

• In addition to the ~0.1 mm width tolerance, you now also add 0.25 mm tolerance to the top flat.

• That adds up to a cumulative tolerance of up to ~0.6 mm (0.024”).

• This works fine for screw-fixed mounts, but it’s a disaster for QD mounts — they become much harder to get consistently straight and repeatable across different rails.

What we do at Spuhr:

• Fixed mounts: We follow the NATO/STANAG recommendation (red surfaces) for maximum straightness and repeatability.

• QD mounts: We stick to the original Picatinny design (green surfaces only) to keep tolerance stack as low as possible and ensure compatibility with as many rails as possible.

The last picture shows one of our custom inspection fixtures for QD mounts — we use it to verify that they sit reasonably straight despite rail variations.

NATO really missed an opportunity by not tightening up that loose 0.25 mm top-flat tolerance — it would have made QD systems so much better!
