ABERDEEN PROVING GROUND, Md. — As the Army looks to shrink its battlefield footprint, its researchers and engineers are finding ways to make the nerve center of the battle — command posts — lighter, more capable and easier to set up and tear down.
A recently concluded three-year program aimed to do just that, with everything from the shelter devices used to house a command post's gear, to refitting old and new vehicles, to moving an entirely vehicle-mounted communications system off the truck and into the ruck, cutting its weight by two-thirds in the process.
These are some of the ways that experts with the U.S. Army Research, Development and Engineering Command's Communications–Electronics Center are finding to make command posts more mobile, resilient and effective against enemies that can quickly target and destroy massed formations.
Some of the advancements include the Expeditionary Command Post shelter, a 20-foot box with integrated power outlets, air conditioning, network cabling and video distribution system. It's containerized so that it can be hauled on a truck or sling loaded under a helicopter.
A four-soldier team can set up the structure within 30 minutes as the remaining command personnel hook up the computers, radios and other devices inside of the structure.
Jim Bell, operations expert with RDECOM, told Army Times that soldiers with the 1st Armored Division's 2nd Brigade Combat Team set up the shelter in those time frames during field exercises. And during an experiment at Fort Hood, Texas, soldiers moved the shelter with a CH-47 Chinook helicopter.
An even more mobile option that researchers have put together is the Light-Mobile Command Post, a pull-out table and tent combination that is installed in the back of a Humvee. It includes fixed TV monitors, built-in radio networks, cabling and computers.
The system was designed primarily for light infantry units, but a similar configuration has also been installed on tracked command vehicles for armor units.
This post can be voice comm and position location tracking operational within 15 minutes and fully operational in 30 minutes.
Another Humvee-based answer to mobile command is a reconfigured command and control vehicle dubbed the Command Post Platform–Improved. It has a built-in power and cooling system and spots for two cases containing the capacity for six computer servers, enough to run a brigade's worth of data.
The setup includes seven radio nets, HF, UHF, VHF and SATCOM, and links for fiber optic, standard and secret lines of communication.
A small but important feature allows the user to power the systems from either vehicle or external power. The system also has a 15-minute power backup so that the servers can continue to run as power is switched.
Beyond a structure or tent solution, researchers have also outfitted small and mid-size all-terrain vehicles, specifically the Polaris MRZR. The focus of these is to provide airborne or air assault operations with a full-fledged command post in a smaller package.
The smaller MRZR uses a modular system that can be pulled and reinstalled quickly into another vehicle, should the ATV be disabled.
And it has an extra-powerful alternator that can produce 120 amps, double the amperage of a Humvee alternator.
It also includes a first-ever all-around handset that can plug in and communicate whether the speaker is using radio, Voice over Internet Protocol or VOIP, and other computer-based voice applications.
On top of all these advancements, the Army also is working on reducing what was 60 pounds worth of gear that previously was only used during mounted operations into a much lighter, man-portable package.
“They were ripping stuff off of vehicles and coming up with a power source,” said Brad McNeilly-Anta, command post consultant for RDECOM. “That wound up with a 60-pound item, and they were jumping with it at the 82nd Airborne.”
Not the most convenient package to haul to the ground.
The expeditionary Joint Battle Command Platform is a line of sight, two-way transmission that includes a tablet, battery, peripherals and a new fueled power source that allows it to run for more than 24 hours of continuous operations.
Adjustments and replacements to the ruggedized computer, power source, transceiver and encryption device have trimmed the weight down to 23 pounds.
Experimenters adapted a 1 L methanol power source to run the system but have also successfully experimented with windshield wiper fluid to run the system, McNeilly-Anta said.

By: Todd South Army researchers are speeding up development on key conventional munitions, from field artillery to long-range missiles, and making them more deadly when they land. At a panel hosted by Defense News at the annual Association of the United States Army annual meeting, commanders with the Army's Research, Development and Engineering Command, Program Executive Office-Ammunition and the Long-Range Precision Fires Cross-Functional Team gave a few updates on those efforts. Brig. Gen. Alfred Abramson III, head of PEO Ammo and Picatinny Arsenal, New Jersey, told audience members that his researchers are finding the quickest ways to go after extending ranges, saying that the XM1113 round will be “critical” for the conventional artillery in the Extended Range Cannon Artillery program, a centerpiece of artillery modernization. Abramson noted that the existing M795 High Explosive artillery round, the base of the 155mm munition portfolio, includes about 614,000 rounds in the nation's stockpile. But those rounds only reach out to about 30 kilometers. The problem developers face in pushing the ranges of conventional rounds is keeping them both accurate and having a real effect when they strike, he said. “You want to push it out to 70 kilometers and ensure it's not just a long-range paintball,” Abramson said. The XM1128 pushes those ranges to about 40 kilometers currently. But work with “lithographic fragmentation technology,” Abramson said, makes the round more lethal on target. Col. John Rafferty, director of the LRPF CFT, said that recent testing has gotten 155mm artillery rounds to the 60-kilometer range at the Yuma, Arizona, testing facility. Abramson said that his organization has seen a significant spike of about $2.5 billion for fiscal years 2017 to 2022 funding for ammunition and armament systems products. Another $1.5 billion has been allotted to update the aging ammunition manufacturing plants across the Army, he said. Recent Overseas Contingency Operations funding for 2019 was marked at about $4.1 billion simply to replenish munitions consumed during combat. What's being done to advance the science? Maj. Gen. Cedric Wins, commanding general of U.S. Army Research, Development and Engineering Command, said that over the past year, $900 million was realigned for science and technology development for the LRPF initiatives, and another $500 million was also realigned for the Air Missile Defense CFT. His organization just completed a six-month study of energetics propulsion that included a detailed study of adversary capabilities and advancements over the past two decades. It also looked at how those advances were achieved and what gaps exist in the United States' armaments, he said. While the study has not yet been released to the public, he said two non-technical gaps that the United States must correct are in their ability to collaborate with global partners and science, chemistry and energy experts within government. Further down the development pipeline he said was a shortfall in transitioning the research to the PEOs for development and fielding. One tech challenge is the existing stockpiles. As the developers push the capacities of conventional rounds and their systems they must also maintain “backwards compatibility” with the substantial munition stockpiles, he said. https://www.armytimes.com/news/your-army/2018/10/08/army-leans-on-scientists-to-push-the-boundaries-of-munitions-range-precision-lethality
